i stopped tomcat
paste myapp.war into webapps folder.
start tomcat
call in browser
http://localhost:8080/myapp/index.jsf
see 404
also tomcat does not generate log files under logs directory.
I am using eclipse to start and stop tomcat, and my tomcat 7 is an unzipped version.
to be sure that my war file runs on server, i remove same project from tomcat in eclipse servers view.
repeating question, but i think my situation is a little different, tomcat does not generate logs.
a note: i generate war file by right click in eclipse-> export war file.
thanks for any idea.
If you are launching tomcat from within Eclipse (using the webtools tomcat server adapter) you will have to make sure you have changed the settings to use the installation directory to launch instead of the default which uses a separate location for loading and deploying webapps. So if you add a war directly into the webapps folder, the server launched from Eclipse server adapter wont have that directly setup in the server.xml configuration.
So you should use the startup.bat/startup.sh in the tomcat/bin folder. If you do, you need to make sure that you don't just copy the .war file into the webapps, but rather unzip the war file into a directory folder called "myapp"

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 deployed a war file through management console of JBOSS EAP to my company server. I lost my source code accidentally deleted. How can i download the file that's now running on the server to my local machine. Please help me
When you have access to JBoss directory and you pack source code into jars so:
You deploy a war file through the management console your archive is saved on path:
JBOSS_HOME/standalone/tmp/vfs/deployment (in case when you are in standalone mode)
There you can see unpacked war file with jars. But java source code is usually converted to bitecode and you can not get code from it. Maybe you compose your jar with source code and you can see source code.
But unfortunately I don't know way how to do it through Management console.
In the management console of JBoss, go to "Deployments", click the applicable deployment, click "View". Then you have the possibility to browse through all files in the war. Downloading the full war means clicking the war, and on the right, click "Download".
(all based on the 3.0.19.Final console version)
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 have created myProj.ear file and copied it into the deploy folder of the JBoss server.. How to run my project after starting the jBoss server?
I have been using war file and
deploying it in Tomcat till now to run
my project.... I am having a new
requirement to run the project in
JBoss. So, I converted my war file
into an ear file using the command Jar
-cvf myProj.ear ., Should I change anything in my project to run
the application in JBoss or just
copying my .ear file in to the jBoss
deploy folder is enough?
JBoss normally support hot deployment - meaning that if your application was deployed correctly (watch the console), it can be accessed via the browser (if you have a UI) or via web services, managed beans or any other interface you have provided.You can see the status of your application on the JBoss Admin Console. You can reach it by typing the URL of your JBoss installation. If you run your vanilla JBoss locally, you should be able to find the console under http://127.0.0.1:8080/admin-console
To reiterate: there is no explicit startup necessary, JBoss handles it for you.
Deploying an application in JBoss is pretty straightforward. You just have to copy the EAR file to the deploy directory in the 'server configuration' directory of your choice. Most people deploy it to the 'default' configuration, by copying the EAR file to the JBOSS_DIR/jboss-as/server/default/deploy directory.
Once copied, just run run.sh from bin, you can use the following params to bind it to an ip (-b) or binding it to anything other port (-Djboss.service.binding.set)
./run.sh -b 9.xxx.xxx.xxx -Djboss.service.binding.set=ports-01
Once you run it, Look at the console for error message. If everything goes fine you'd see "Started J2EE application" after couple of seconds.
If there are any errors or exceptions, make a note of the error message. Check that the EAR is complete and inspect the WAR file and the EJB jar files to make sure they contain all the necessary components (classes, descriptors,
jboss-deployment-structure.xml etc.).
You can safely redeploy the application if it is already deployed. To undeploy it you just have to remove the archive from the deploy directory. There’s no need to restart the server in either case. If everything seems to have gone OK, then point your browser at the application URL.

I use Tomcat 6.0 and Eclipse 3.0 under Linux and I try to deploy a WAR in Tomcat. The problem is that the server is managed by Eclipse and I have some Eclipse project deployed. I tried to modify the server.xml file then launch Tomcat via Eclipse but it doesn't work:
Could not load the Tomcat server configuration at /Servers/Tomcat v6.0 Server at localhost-config. The configuration may be corrupt or incomplete.
I tried to extract the war in the webapps directory but the webapp is still inaccessible.
What is the best practice to deploy a War ?
Tomcat behaves differently in development and production mode. When you develop your webapp in Eclipse there is no reason to deploy a WAR file of your application as a WAR during development.
Just go to the "servers" view and add a new server (you should already have done this otherwise you could not create your Dynamic Web project). In the server view you should see the server you created (Tomcat at localhost or something similar) just right click it and go to the Add and Remove section. Here you can add and remove the Dynamic Web projects you created in Eclipse. Once you added your project, all you have to do is click the green start button in the servers view and your app should be available in at localhost:8080/mycontext.
When you're done building your app just right click the project and go the the Export section in the menu. You should be able to export a WAR file. Once you have your WAR file you can upload and deploy that on a Tomcat instance that is NOT tied to Eclipse running in dev mode.
Yes, in a way, you can deploy a war in the dev mode.
I have the same problem.
I have an Eclipse webapp project, which Eclipse deploys to an instance of Tomcat run by Eclipse, so I can hot-edit the project.
This Web project needs to use resources published by another webapp that has to be run within the same instance of Tomcat. The other webapp is a completed project by someone else, so it is already in a war form.
I needed to File->Import the war as an Eclipse project and let Eclipse deploy it to the same instance of Eclipse, in order to run it in the same instance of Tomcat in which my webapp also runs.
The problem is that some wars work this way but some others do not, while all of them work perfectly fine in a stand-alone Tomcat (started by startup.sh). I can't figure out why.
This is old but is one of the first answers in google search.
You can import the war file:
A Web Archive (WAR) file is a portable, packaged Web application
that you can import into your workspace.
Before importing a WAR file,
you should first determine if the WAR file contains needed Java™ source
files. When importing a WAR file into an existing Web project, the imported
Web deployment descriptor files are either not changed or overwritten by the
ones included in the imported WAR file, based on your response to the prompt
that is provided. In either case, this action does not represent a
merging of the two sets of deployment descriptors.
To import the
Web project resources in a WAR file into your workspace, complete the following
steps:
Select File > Import
.
In the Import dialog, select WAR file and
then click Next.
Locate the WAR file that you want to import using the Browse button.
The wizard assumes you want to create a new Web project with the
same name as the WAR file. If you accept this choice, the project will be
created with the same servlet version as specified by the WAR file and in
the same location. If you want to override these settings, you can click New and
specify your new settings in the Dynamic Web Project wizard.
Click Finish to populate the Web
project.

If all you have is a binary WAR (no source code), it cannot be installed within Eclipse. This can happen in certain scenarios outside of normal development workflows. Here's the work-around solution:
Launch another instance of Tomcat (outside Eclipse).
Modify the tomcat-users.xml file to enable admin
Go to http://localhost:8080/manager/html
Scroll down to WAR file to deploy
Click Choose File (next to Select WAR file to upload) and click Deploy.
