I am using tomcat server , I build my dynamic web project and add to it external js files and other files ... it run fine ... But Now the tomcat run the specific code which I use js files and other files not correct .. I did not knew what the problem the tomcat was run fine why Now it did not run fine my dynmic web project ... any body can help ?
Export your eclipse project as war file and place in the tomcat/webapps folder.
Start your tomacat service here http://help.eclipse.org/kepler/index.jsp?topic=%2Forg.eclipse.wst.webtools.doc.user%2Ftopics%2Ftwcrewar.html

I have imported all the jar files required for my spring web application in build path as well as in lib folder(under webcontent folder). But not showing up in server tab once the project added to server to run. Can anyone tell me how to fix this? All jars need to be shown there and I'm not able to run the application because of this.
I am developing a web app in Eclipse for deployment to a Tomcat server. Currenly, it works fine when I launch it from within Eclipse, using a Tomcat installation on the localhost. But when I export a .war file and install it on a remote server, it fails because of a mismatch between the file system in Eclipse and the file system in the .war file.
When Eclipse created the Java EE project for me, it created the following directory structure:
app
src
WebContent
I put all of my Java source files---servlets and classes---in the src directory, and all of the Web files---.jsp, .html, and various .xml resources---in WebContent.
So that my app could use the .xml resources, I put them all in a WebContent subdirectory named, not coincidentally, resources.
I then defined a variable pointing to these files...
path_to_resources = "WebContent" + pathMrkr + "resources" + pathMrkr;
// where pathMrkr = System.getProperty("file.separator")
...in each class that needs to access the .xml files.
This works well when I run the app from within Eclipse. But when I export and deploy the app if fails. The .war file Eclipse creates does not include a WebContent folder, so the search for resources fails, and the app crashes, shutting down Tomcat in the process.
So, I guess I'm looking for some advice on how best to structure Eclipse or my app so that a single code base works both in Eclipse on the localhost and from a .war file on a remote server, with a minimum of fuss and fidgeting with build configurations or having to manually edit the .war file.
While I don't think it's pertinent, for the record my system is:
Eclipse Luna, on a Windows 10 localhost, with Tomcat 8 and Java 8. The remote server running in the cloud is a CentOS 5.5 system running Tomcat 7 and Java 8.
Thanks.

I have created a simple gwt application (with gwt 2.4) that makes a single RPC call.
When I run this in GWT Dev mode, it runs fine, however when I try to run this on a server-
this is the message that I get --
POST http://app.sparkcrawler.com/com.arvindikchari.auth.App/AuthenticationService 404 (Not Found)
I have copied all files from the WAR folder in my Eclipse GWT project, to the web server's folder. The web server uses Tomcat 5.5(with Cpanel control panel). I copied these files, after successfully compiling the files ("GWT Compile Project")...
What have i done wrong here? Have i missed some files? I have copied everything from war folder, including "WEB-INF" folder and its contents, to the web server.
I think, copying the Eclipse project's WAR folder is not the appropriate way to deploy a GWT application to a server.
You first have to compile for production mode (see Understanding the GWT compiler), then with the resulting JavaScript files, create a WAR including server side classes which you can deploy to a Tomcat server. (See Deploy a GWT Application)
You can use Ant or Maven to automate this process.
I know there are a bunch of posts on this topic, but I can't seem to figure it out. Here is my setup:
- Eclipse Indigo
- Tomcat 6
- Struts WAR file that I imported into Eclipse from http://www.manning.com/dbrown/SampleApplication.zip
I added the server to Eclipse, and added the project to the server. It runs fine, but I'd like to make some changes to the XML and java files (not the jsp files). I was under the impression that Eclipse takes care of the deployment after I save and restart the server, but I guess this isn't the case. I looked into creating an ant file to do a custom build, but I'm not really sure how to make it since I don't even know how to do a deployment "manually". How would I go about doing a manual deployment? Thanks.
A war file is usually created by exporting it from an IDE like eclipse, netbeans, etc.
While generating a war file there is 2 options,
You can include your java files with it
You can avoid java files from it.
In both the cases class files will be there which are created from java files. Class files will be able to take care of the actions of java class.
If the war file which you down loaded is not having those java files, you will not be able to use it with eclipse, where as it will work fine if you are putting it into tomcat directory for running.
For running a war file manually just put it into tomcat webapps folder and run tomcat.
Then you can access the pages using the url.
http://localhost:8080/yourprojectname/
If you want to check whether the war file contains any java files, after starting the tomcat server it will extract the war file into the same directry, where you can search for java files.
If you want to run the project from eclipse,
import it into eclipse, open index.jsp page
right click-> run as-> run on server
if you have not yet configured the server yet,select the server in the list, specify its installation path, then add projects into server in next step, finish it. then it will load your project.
Please provide little more details so that we can help you better.
manual: copy the war in the tomcat folder then start tomcat.
if you want to use eclipse you need to click redeploy war first by right clickling the deployed war in the servers tab under tomcat.
I am tring to configure a dynamic web project using eclipse helos. I use tomcat 6. When I add the libraries to the WebContent/lib it works fine. But I want to a folder called lib in the project's root level(root/lib). When I put my library files to that folder it builds fine. Run fine to the login page. When I try to log in it gives
"java.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool"
Please help me with this.
You're creating a web app and deploying it as a WAR file in a Java EE container. That means that your deployment must follow the WAR standards. Put your JARs in WEB-INF/lib. The container will find them there.
Tomcat 6 and 7 have changed things up so JDBC driver JARs need to go in the server /lib directory. The app server expects to find them with its class loader. Try putting the MySQL JDBC connector JAR in /lib and see if that helps.
