I am trying to use Tomcat 6.0 as a web development server within SpringSource Tool Suite 2.7.1. I create a runtime, download tomcat, create a server, etc as per these instructions http://www.ibm.com/developerworks/opensource/library/os-eclipse-tomcat/index.html#N10148
When I try to run a web app on the server though I get the following error:
The archive: /Servers/Tomcat/bin/bootstrap.jar which is referenced
by the classpath, does not exist.
I know this bootstrap.jar file does exist in the exact place it says it should be yet it still causes an error. Any ideas?
You might want to check/manually edit your path by going into server properities:
In Servers view,
1) double-click on Tomcat server.
2) Then click on Overview of Tomcat settings appears.
3) "Open launch configuration" then Classpath
4) Edit User Entries here
The trick here was that the location of the jar was inside the Eclipse/STS project directory. STS stores its server configurations inside the /Servers folder and I had decided to store the tomcat runtimes here as well for neatness. Placing the runtimes elsewhere and trying again solves this issue.
None of the above answers provide proper concrete solution.
I faced exactly same issue and i figured out a very simple solution.
Open Eclipse and remove all entries of Apache server
Delete Servers from explorer tab, delete Tomcat from server explorer window, delete server from Window > Preferences > Server > Apache tomcat, delete it, also delete servers folder inside EclipseProjects.
Place Apache tomcat folder outside the project folder anywhere you wish to, you can place in Eclipse_Projects folder but not inside EclipseProjects/projectxyz/.
Now add server in eclipse the usual way and give path of this new location.
This should work!
I had similar issue. This is what worked for me:
When the path begins with slash like: "/Servers/Tomcat/bin/bootstrap.jar" it means that the local project is refered. In the picture - I had 'pivotal-tc-server-developer-3.2.8.RELEASE' as the name of the project.
Open the project ('Servers' in your case or 'pivotal-tc-server-developer-3.2.8.RELEASE') so it is accessible to Eclipse.
The jar should be now visible.
Alternatively go into Run Configurations; delete jars, and add it as an external jar.
Or you may delete the servers configuration, and configure the server again. This works when you may have changed the directory of the server.
I googled my way here on the search terms, "the specified tomcat directory does not exist". (I had moved it from one directory to another.)
For others here for that reason, my solution was to go into Window -> Preferences -> Server -> Runtime Environments and update it there. Then to update the JARs, as in Marcin Wasiluk's answer.
I was also facing same issue and solved it as follows :
My conclusions :
1) In my case issue was coming as I shifted the location of the Tomcat.
Solution :
2) double clicked on the server configured in the eclipse.
3) Click on Open Launch configuration.
4) Change the classpath under classpath tab to the new location.
Hope this would help.
I have faced the same problem.
Solution: In Project Explorer--> Servers(right click) --> Run As --> Run Configurations(click) --> (Select "Tomcat v7.0 Server at localhost") --> Arguments(tab) --> Working directory(bottom of window) --> others : (click workspace) --> select the "boostraps.jar" from -->Server.
Eg., My workspace.MY path is:
Project Explorer --> Servers(right click) --> Run As --> Run Configurations(click) --> (Select "Tomcat v7.0 Server at localhost") --> Arguments(tab) --> Working directory(bottom of window) --> others : (click workspace) --> /home/ciprus//Servers --> click apply.
this could happen if you probably used previous tomcat server in eclipse, so deleting server and its configuration and creating another one will make it work .
You can try as below steps:
Open Window -> Preferences -> Server -> Runtime Environments
Click add button, choose the what's kind of server you use.
Click next button, give a name to your runtime server and the path of tomcat.
New a new server with the new created runtime server
same problem in my case also i solved::
just remove your older tomacat server and add tomcat 8.0 version only
If you have unzipped downloaded Tomcat archive into Eclipse Servers folder, User Entries in classpath have relative path (e.g. /Servers/....) of bootstrap.jar and tomcat-juli.jar which path I guess is not accessible as a relative path.
Once I removed Tomcat installation directory (with files) outside Eclipse's Servers folder, delete the old configuration and re-add Tomcat, everything worked as expected.
I hope this helps narrow down the cause.

I'm using Tomcat 7 on Eclipse Juno. I use workspace metadata as server location (Please see my tomcat configurations below).
Also I got a Server project in eclipse [please see the image below] with separate server.xml and other configuration files.
Normally it works fine. The issue came across after I changed the server.xml (in eclipse project) for SSL configurations.
Configurations are working fine. But each time I run the project (Run-->Run on Server) server.xml get modified to the default version. My customized SSL changes are missing.
Also I tried to change server.xml in tomcat installation location (C:\apache-tomcat-7.0.35\conf), but it didn't pick from eclipse.
Can anyone please help me on this?
Thanks
In {workspace}/Servers you will find a folder for every Tomcat configuration, containing several configuration files, including the server.xml. There you then can edit the file directly.
To get changes taken into account restart Eclipse. That is imho better than removing and adding the configuration back all the time. Tested using Eclipse Mars and Tomcat 7.
(the solution is from: Eclipse with tomcat - eclipse modifies server.xml)
I found an applicable solution but not a perfect one.
What I have done is;
1.Changed server.xml file in installation location (In my case C:\apache-tomcat-7.0.35\conf)
2.Remove tomcat server from eclipse server panel (please see the image below)
3.Create a new server in eclipse server panel.
4.Then Server project will be generated new server.xml with my customized changes.
5.The trick is, initially eclipse picks server.xml from installation location when create a new server in panel.
Thanks
Make sure you are editing the files right beneath the tomcat server folder, not the ones beneath the config folder. Check the attached screenshot for the files I'm referring to.
I had this problem too, and the solution worked (I don't have enough reputation points to vote up the answer).
On a similar note, I had to make configuration changes to a port number and that also required me to delete and re-add my tomcat instance from STS (spring tool suite).
On Eclipse, double click on Server to view properties.
check "publish module contexts to separate XML files", and save it.
Run Tomcat server.
Eclipse will be create conf/[enginename]/[hostname]/[appname].xml without touching server.xml
Make sure that the path in the server.xml is same as in the Web project Settings.
To see the Web Project Settings: Right click on the project >> Properties >> Web Project Settings.
Always give the project path over here. The path in server.xml will automatically updated.
Clean Tomcat Work Directory & Republish the project.
I integrated Tomcat 7 in Eclipse. When I start it using Eclipse, it shows that Tomcat is up and running, but when I go to http://localhost:8080 in my browser, it gives me following error:
HTTP Status 404 - /
type Status report
message /
description The requested resource (/) is not available.
Apache Tomcat/7.0.23
I tried changing the port in server.xml just in case if 8080 is used by another service, but it didn't work either. How can I solve it?
What are you expecting? The default Tomcat homepage? If so, you'll need to configure Eclipse to take control over from Tomcat.
Doubleclick the Tomcat server entry in the Servers tab, you'll get the server configuration. At the left column, under Server Locations, select Use Tomcat installation (note, when it is grayed out, read the section leading text! ;) ). This way Eclipse will take full control over Tomcat, this way you'll also be able to access the default Tomcat homepage with the Tomcat Manager when running from inside Eclipse. I only don't see how that's useful while developing using Eclipse.
The port number is not the problem. You would otherwise have gotten an exception in Tomcat's startup log and the browser would show a browser-specific "Connection timed out" error page (and thus not a Tomcat-specific error page which would impossibly be served when Tomcat was not up and running!)
Following steps helped me solve the issue.
In the eclipse right click on server and click on properties.
If Location is set workspace/metadata click on switch location and
so that it refers to /servers/tomcatv7server at localhost.server
Save and close
Next double click on server
Under server locations mostly it would be selected as
use workspace metadata Instead, select use tomcat installation
Save changes
Restart server and verify localhost:8080 works.
Copy the ROOT (Default) Web App into Eclipse.
Eclipse forgets to copy the default apps (ROOT, examples, etc.) when it creates a Tomcat folder inside the Eclipse workspace.
Go to C:\apache-tomcat-7.0.27\webapps, R-click on the ROOT folder and copy it.
Then go to your Eclipse workspace, go to the .metadata folder, and search for "wtpwebapps". You should find something like your-eclipse-workspace.metadata.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps (or .../tmp1/wtpwebapps if you already had another server registered in Eclipse).
Go to the wtpwebapps folder, right-click, and paste ROOT (say "yes" if asked if you want to merge/replace folders/files).
Then reload localhost:8080 to see the Tomcat welcome page.
I did what BalusC said but it was not enough for me, I had to clean the Tomcat workdirectory : ( Click right on right on Tomcat in the Servers Tab -> Clean Tomcat Work Directory )
Please check in your server specification again, if you have changed your port number to something else.
And change the port number in your link whatever new port number it is.
Also check whether your server is running properly before you try accessing your localhost.
If you are new in JSP/Tomcat don't modify tomcat's xml files.
I assume you have already deployed web application. But to be sure, try these steps:
- right click on your web application
- select Run As / Run on Server, choose your Tomcat 7
These steps will deploy and run in the browser your application. Another idea to check if your Tomcat works correctly is to find path where tomcat exists (in eclipse plugin), and copy some working WAR file to webapps (not to wtpwebapps), and then try to run the app.
If options under Server Locations are grayed out, note the message in the section title: "Server must be published with no modules present". To publish the server, right click the name of the server in the Server window and select "Publish".
Sometimes cleaning the server works. It worked for me many times.This is only applicable if the program worked earlier but suddenly it stops working.
Steps:
" Right click on Tomcat Server -> Clean. Then restart the server."
I had the same problem with my localhost project using Eclipse Luna, Maven and Tomcat - the Tomcat homepage would appear fine, however my project would get the 404 error.
After trying many suggested solutions (updating spring .jar file, changing properties of the Tomcat server, add/remove project, change JRE from 1.6 to 7 etc) which did not fix the issue, what worked for me was to just Refresh my project. It seems Eclipse does not automatically refresh the project after a (Maven) build. In Eclipse 3.3.1 there was a 'Refresh Automatically' option under Preferences > General > Workspace however that option doesn't look to be in Luna.
Maven clean-install on the project.
** Right-click the project and select 'Refresh'. **
Right-click the Eclipse Tomcat server and select 'Clean'.
Right-click > Publish and then start the Tomcat server.
In my case, I've had to click on my project, then go to File > Properties > *servlet name* and click Restart servlet.
For me, my Eclipse installation was hosed - I think because I'd installed struts. After trying a dozen remedies for this error, I re-installed Eclipse, made a new workspace and it was OK. Using Kepler-64-Windows, Tomcat 7, Windows 7.
This worked for me:
Project > Build Automatically (Make sure it's turned on)
Project > Clean ...
Right click Tomcat > Properties > General Tab > Switch Location (switch from workspace metadata to Server at localhost.server)
Restart Eclipse
Run Project As Server
Apache Tomcat/7.0.23 service is not loaded or enabled. Pls check the service status and other app which is using 8080 port currently. To check this use netstat command and observe whether another app is occupying the port 8080!
This is the error that I got when I created my first Axis2 web service using Eclipse. After I wrote the class, I created the web service with Apache Axis2. When I click the start server button in eclipse it gives an error message:
Could not publish server configuration for Tomcat v6.0 Server at
localhost.
Multiple contexts have a path of "/FirstApache".
FirstApache is the dynamic web project that I created before. I selected the correct web project from the configuration part in the web service wizard.
How can I fix this?
Search for the server.xml file and check your <Context> tags, probably there are multiple definitions for the same path. Remove the duplicates and it should work for you.
Check out the answer here.
Auto-format the xml file (control + shift + f) since the second <Context> tag may be on the same line, but outside the viewport and really far away from the visible one.
In STS/Eclipse go to "project explorer" or "package explorer" and
there is a folder called "server." Open it and you will find server.xml file. Inside this file at the bottom you find a definition like
<Context docBase="myproject" path="/myproject" reloadable="true"
source="org.eclipse.jst.jee.server:myproject"/>
You might find duplicates of the same definition that you would need to remove.
In Eclipse, go to the Servers project. Open the tree for the Tomcat version you are using. Open file server.xml and verify your Context tags.
In your eclipse IDE on project explorer acess the server.xml like in:
And remove context tags with duplicates references for your project:
Go to server.xml and Search for "Context" tag with a property name "docBase".
Remove the duplicate lines here. Then try to restart the server.
Go to the Servers project in eclipse, under your runtime server configuration(in my case Tomcat v7.0 Server at localhost-config) go to server.xml file then search for <context> tag,
normally you will find more than one context tag, delete them and run your application in the appropriate server that will work now.
in my case i have found duplicate Context tag :
<Context docBase="my-project" path="/my-project" reloadable="true" source="org.eclipse.jst.jee.server:my-project"/><Context docBase="my-project" path="/smartphone-selfcare" reloadable="true" source="org.eclipse.jst.jee.server:my-project"/></Host>
In eclipse using tomcat you just open this server.xml file and find Context tag and here you see your context name is more then one you just delete useless contexts and restart your server it will working....
In your project's Properties, choose "Web Project Settings".
Change "Context root".
Clean your server
now you can restart your server
Eclipse >> project explorer >> servers >> server.xml >> tag >> remove duplicate tag of your project
Try to delete the existing tomcat server in the server console. If you don't have the console then you can go to "Show view ->server", delete the server by right clicking on it, then add a new server.
If you are using Tomcat 7 and Eclipse, click on the Tomcat server and then goto the modules tab. There you will find the duplicate entry. Remove both the entry and redeploy the application. You are good to go now.
On a related note, if you have copied a project or in anycase, have the same context path for 2 'active' projects, you have to change the context path of one of them, then clean the tomcat server settings, then republish the servers
see this in-more detailed answer
Simply remove the server in Eclipse and add tomcat server again. than shutdown the tomcat in tomcat/bin/shutdown.bat file and start the server in eclipse.
I had that problem before. I just solved it by expanding the tomcat tree and delete the folder that is causing the clash. in your case is /FirstApache. after you delete it. then you rerun it, you should be able to run. If it happens again, delete it and try again.
This error occurs when you copy a project than past it, and then you change the name of that project.
in such a case, follow the following steps.
Step-1: you need to edit your web.xml file.
remove servlet and servlet-mapping of the previous projects.
Step-2: got to SERVER--> server.xml--> find context
Example :- Context docBase="JSPandServletDemo" path="/JSPandServletDemo" reloadable="true" source="org.eclipse.jst.jee.server:JSPandServletDemo"/>
now you just need to change the pathname to your current project name.
Good Luck
Happy Coding :)
Remove the space or empty line in server.xml or context.xml at the beginning of your code
In my case I found duplicate paths in Servers/Tomcat5.5 at localhost-config/server.xml under tag. Removing the duplicates solved the problem.
Delete org.eclipse.wst.server.core and org.eclipse.wst.server.ui from .metadata/.plugins of wrokspace
delete the server from eclipse then reconfig the server in eclipse.
Go to servers
Click right at Tomcat
click at Add and remove
then click at remove all
It is pretty easy to do for me. If you created the server and you know the path of the directory where the server files are located then one can simply open the server.xml file which is right inside the server's folder.
Just edit the file to remove repeated <Context...> tag for the specific project which on running threw the error previously.
In Eclipse, in Servers, expand Apache Tomcat
Delete all the "Contexts"
In Eclipse
Right click on the project
click on properties and it opens the properties window
select web project settings from the properties window
change the context root
If you are using STS and your server is Pivotal Just double click on the server and go to >Modules tab >display Configure the Web Modules on this server.>you can just remove modules and run once again.
//Trying to do more than one thing to the object in the same context,
//the solution is to work on single context objects
public class SingletonContext<TContext>
where TContext: DbContext,new()
{
private static TContext _context;

{
}
public static TContext GetInstance()
{
if (_context == null)
{
_context = new TContext();
}
return _context;
}

Im using Eclipse Galileo, and have configured it for Apache Tomcat . I have added Apache Tomcat 6.0 to Windows->Server->Runtime Environments, with the following settings:
Tomcat Installation Directory - C:\apache-tomcat-6.0.24\apache-tomcat-6.0.24
JRE - Workbench Default JRE (This points to C:\Program Files\Java\jre6)
Now, I create a Dynamic Web Project, and add a JSP file to it. But, when I run the project I get the following error:
The Tomcat server configuration at \Servers\Tomcat v6.0 Server at localhost-config is missing. Check the server for errors.
Any way to fix this?
Probably, you have some problems with your server's configuration.
Follow these steps to remove and create a new one, it might help you.
In Eclipse
1. Window -> Show view -> Servers (If you cannot see it, you might need to choose Others -> Server)
2. From Server view -> Delete the server which has problems.
3. Right click -> New -> Server : to create a new one
In my case, after new server was created, I get rid of this "localhost-config is missing"
I faced the same problem once. THe reason for this is that even though the server is available, the config files are missing. You can see the server at Windows -> Show view -> Servers. Their configuration files can be seen at Project Explorer -> Servers. For some reason this second mentioned config files were missing.
I simply deleted the existing server and created a new one with this the config files were also created and the problem was solved!
Similar solution is given at here by Emertana EM
java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
In Eclipse Neo
1. Window -> Show view -> Servers
2. Right click on server -> choose Properties
3. From General Tab -> Switch Location
As Yoni already mentioned, you probably deleted the project named "Servers" from your Project Explorer. If config files for the server still present on a file system, the quickest way to restore it will be Right Click in Project Explorer->Import->General->Existing Projects into Workspace, then select the root dir where Servers dir located, set checkbox near "Servers" and finally click Finish. If everything works as expected, you should see the 'Servers' project added to the Project Explorer view and your old config files will be there. Finally, save the tomcat configuration which you had open. You can startup your Tomcat server without errors now.
From project explorer ,just make sure that Servers is not closed
You need to define the server instance in the Servers view.
In the box at the right bottom, press the Servers tab and add the server there. You by the way don't necessarily need to add it through global IDE preferences. It will be automagically added when you define it in Servers view. The preference you've modified just defines default locations, not the whole server instance itself. If you for instance upgrade/move the server, you can change the physical location there.
Once defining the server in the Servers view, you need to add the newly created server instance to the project through its Server and Targeted runtime preference.
If you're not too attached to your current workspace you can create a new workspace, follow BalusC's steps for server creation, and recreate your project in the new workspace.
I got the same error after installing Eclipse Java EE IDE for Web Developers(Juno) but using the workspace of a much older Eclipse installation. When I created a new workspace I was able to get my Tomcat server running without this error.
Did you, by any chance, deleted stuff from your workspace, or moved it around?
When you create a server for the first time, either globally or through the project's "run on server" settings, Eclipse creates a project in the Servers view, as BalusC pointed out. Eclipse stores this server inside your workspace, in a project called Servers. The project needs to be open for tomcat to run.
(If you want, you can store the server settings elsewher. You can right click and open the server instance from the Servers view and configure various parameters and locations)
This happens when Eclipse shuts down incorrectly - delete the server and then re-create it again.
Remove the server from IDE and install again to it.
In my case, the server list was empty for Apache in "Run Configurations" when I opened
Run > Run Configurations
I fixed this by creating a server in the Servers Panel as in other answers:
Window -> Show view -> Servers
Right click -> New -> Server : to create a new one
this worked for me
In the Server's tab in Eclipse, Stop the Tomcat server
Right-click the server and select "Clean..."
Right-click the server again and select "Clean Tomcat Work Directory..."
In the Eclipse, select the top-level menu option, Project > Clean ...
Be sure your project is selected and click Ok
Restart Eclipse
4th Step is most important.
Go to Servers remove the existing server by clicking delete.
Click the blue link to launch the server.
Set a new runtime environment.
Close the Eclipse and launch it again.
Boom it works!
I have this workspace downloaded off the web and I try running it on a tomcat server from a fresh installation of Eclipse Ganymede. This particular project came with its own workspace.
When I select Tomcat v6.0 I get a message
Cannot create a server using the selected type
Older tomcat versions are available, though.
I guess I have to recreate some configuration setting. The question is which one? This seems to be some odd error as creating a new dynamic web project lets me configure tomcat for both of them
I had a similar problem, but my solution is a little simpler. The problem was causesd by renaming the original folder that was referenced by the server definition.
Go to Window/Preferences/Server/Runtime Environments, remove the broken reference. Then, click 'Add' to create a new reference, select the appropriate tomcat version, click next and you'll see the incorrect path reference. Fix it. Move on.
I had this same problem on Ubuntu 8.10 with Ganymede and Tomcat6. This appears to be some sort of bug with Eclipse. If you try and create a server, and it barfs, you can't create another tomcat6 server. To correct this problem, do the following:
close eclipse
go to the {workspace-directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings directory and remove a file called org.eclipse.wst.server.core.prefs.
start eclipse
add your tomcat6 server in the server tab
kotfu
#id thanks for the solution but something is also hidden in org.eclipse.jst.server.tomcat.core.prefs
So in order to solve the problem
close eclipse
go to {workspace-directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings
remove the files org.eclipse.wst.server.core.prefs and org.eclipse.jst.server.tomcat.core.prefs
Tomcat 5.5
I order to be able to use the tomcat5.5 server you need to have a writeable catalina.policy file as mentioned in
http://dev.eclipse.org/newslists/news.eclipse.webtools/msg16795.html (= add a READ and WRITE permissions to the files in directory "{$tomcat.home}/conf" (chmod -vR a+rw {$tomcat.home}/conf/*). To be more specific, on the file "catalina.policy". After that, the Tomcat server can be added in the Eclipse servers)
(dead link) http://webui.sourcelabs.com/eclipse/issues/239179
and to have the tomcat5.5 stopped before entering eclipse and started afterwards.
Tomcat 6
In order to be able to use the tomcat6 server the proper solution is to have a user instance of the tomcat6 server as described in
/usr/share/doc/tomcat6-common/RUNNING.txt.gz
RUNNING.txt (on the WEB)
My configuration is Debian/Sid, Eclipse 3.4.1. Ganymede
The error view really is key. There is a lot of detail in there -- if necessary, right-click on the entries and copy their contents into your favorite text editor. One problem that can come up, for instance, is that if you have a server configuration already in place, and one of the configuration XML files is unparseable, the server can't be added. This happened to me this evening -- my <Context> element had a linebreak in it, so it was <C(linebreak)ontext>. This prevented Eclipse from recreating the server configuration.
i finally got mine to work with the default Ubuntu 8.10 tomcat. (the debug command-line on eclipse is a wonderful thing) First i had to make a couple of symbolic links and then change the permissions to a file. (you might want to think twice about changing the permissions depending on your configuration, but if eclipse can't read the file it throws and exception and the gui won't let you continue)
sudo ln -s /etc/tomcat6 /usr/share/tomcat6/conf
sudo ln -s /etc/tomcat6/policy.d/03catalina.policy /usr/share/tomcat6/conf/catalina.policy
sudo chmod a+r /usr/share/tomcat6/conf/tomcat-users.xml
Hum it can tricky. Bring the "server" view. If your project has already been deployed, remove it from the server to clean the binding between your project and the server.
Or you can right-click on your project in the project explorer and choose debug on the server. If you don't done it already, Eclipse should ask you to create a server runtime and here you can specify Tomcat 6 and specify the location of your server installation.
You can also see the "problems" view to see any problm in the project imported like the JDK etc...
Look in the error view. If you tried to set one up once and failed, Eclipse seems to try and look there again later just before allowing you to create a new one. If you've deleted the folder or its not there any more, you need to replace it so that you can proceed.
The only way I found to use the Tomcat 6 is changing the ownership of the Tomcat directory to my user. It seems that is not enough to have r/w permissions.
BTW, removing org.eclipse.wst.server.core.prefs erases you workspace configuration.
I had had same problem until I went to tomcat6 configuration directory and added ownership to my user in addition to root:
cd /usr/share/tomcat6/conf
chown root:myusername ./*
chmod 777 ./*
You can choose some better chmod for security, 777 is just a quick brutal fix.
I have Eclipse 3.5 (Galileo) + Fedora 12 + Tomcat 6 extracted from tar(which is why Eclipse could not access it). Eclipse had been complaining "Cannot create a server using the selected type".
What version of Eclipse? Europa? Ganymede?
What do you mean by workspace? An Eclipse workspace is not something you deploy, it holds your projects.
You will need to generate a WAR file (or the folder of files that would comprise the WAR file), a project would typically include an ANT or Maven build script to do this, or if the project used Eclipse's Dynamic Web Project type there might be a 'generate WAR' option somewhere. Without further details I can't help any more.
Adding a new dynamic web project to the workspace seems to 'unlock' the feature.
Changing the ownership to my user worked for me.
In my case, it was the corrupted Tomcat configuration files. Eclipse log was saying:
org.eclipse.core.runtime.CoreException:
Could not load the Tomcat server configuration at
C:\Program Files\Apache Software Foundation\apache-tomcat-6.0.14\conf.
The configuration may be corrupt or incomplete.
Got a new Tomcat distribution, removed the old one and all good now.
Finally got this problem solved on my system.
1) got rid of the apt-gotten tomcats
2) installed a typical tomcat from bins at tomcat.apache.org
3) got rid of my openjdk
4) installed the sun jdk (apt-get)
5) removed my web projects in eclipse
6) noticed that when adding a web project you can set "Target Runtime" - I tried setting it to Tomcat 6 and it let me know there was a problem
Maybe none of the above mattered, but here's what might have mattered:
7) KICKER: Window -> Preferences -> Server - Runtime Environments. Removed any crappy runtime environments here, and added the path to my newly installed tomcat.
This Question is maybe old. But I just ran into this problem. My project was not recognized as a web project (no globe icon in Eclipse ).
Suppose you use maven plugin , it failed to convert to web project with command
mvn eclipse:eclipse -Dwtpversion=1.5
In package Explorer, right-click on the project / configure / Convert to Java Facets project/ Dynamic Web project in Eclipse
Et Voilà
Check the .project file at the root before and after the convert.
You will see new natures.

Instead of deleting config settings files, just go to Preferences -> Server -> Runtime Environments and remove the "forgotten" environment....
Thanks a lot this answer working for me..
