By default gwt applications should have a directory in WEB-INF called deploy/yourmodulename which contains the .symbolmap files which are needed to de-obfuscate client side stack traces.
When I compile via Maven it automatically creates this directory. Unfortunetly this directory is never created when I run my project via Intellij.
I am not running a "GWT" Run/Debug configuration but rather a Jetty configuration that actually runs the GWT compiler with the settings set for your GWT facet and deploys the intellij "artifact".
Any idea why this directory is not present?
Support for 'deploy' directory is added in IDEA 12 EAP builds. Open the artifact editor, press '+' button on 'Output Layout' tab and select 'GWT Compiler Deploy Output' to add 'deploy' directory to the artifact.

I am using STS to develop a large Spring Boot based application. We have multiple maven projects and a parent project to include them all. Each project has own testing code and config files.
When I run the Spring Boot application in the main entry class. The test-classes folder of the depended projects will be loaded into the app running classpath, that causes some conflict of spring bean definition. I have to config every project removing [src/test/java and src/test/resources] from the 'source folders on build path'.
The whole project structure is like below:
app-parent
sub-app-1
sub-app-2
sub-app-3
main-app [running from this project]
main-app project has dependencies on the sub-app-1 ~ 3.
Is there any way to let STS (Eclipse) run a Java App excluding the test-classes folder from classpath? I really do want the testing code under source folder but not have them when the App run.
Besides, I tried open the [run configuration], but it can only add more file to the classpath.
As pointed out by #torsten-crass, verify that Exclude test code is ticked in your Classpath tab of Run configurations in Eclipse.
Here is the screenshot.
when I use an external tomcat everything is just fine. but I need to deploy my project on internal eclipse tomcat server in order to be able to use DCEVM class hot swapping.
When I try to start tomcat server from within eclipse it says it is not able to find one of my service classes I mentioned in my spring security configuration file as a bean.
I also tried to add the project to tomcat class path but it did not solve my problem.
UPDATE
I found out the problem is because when I deploy my web project to eclipse tomcat server, no .class is copied to:
C:\Users\Meysam\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\villapweb\WEB-INF\classes
in fact, this folder contains my src/java/main package structure but no .class is copied in it.
lib folder is fine though (e.g. all dependencies of maven and other stuff copies in the path it is supposed to)
I think there might be something wrong with m2e-wtp plugin. I dont know what!
I am using eclipse 4.3 BTW.
SOLVED
I Solved this issue following these steps:
right click on project in eclipse > properties > project facets
in the right panel select runtimes and select your target server. Apply and ok.
in the server modules list right click on project module and click clean module work directory
right click on the server itself and you can clean both server and tomcat work directory one after another
if that didn't work, try project > clean and also toggle "build automatically" option under project menu item.
Thats it. tomcat now copies all .class files to the target server and you see no ClassNotFound exception as tomcat starts up.

I've followed the steps on the answer but It still wouldn't work for me, so, besides doing these steps once, I've found that doing a refresh on the target after doing a clean install automatically triggers the "Republish" status on the server, so when the server is executed all changes on the compiled classes (new classes and changes to existing ones) are then copied to wtpwebapps when the server is started.
I had almost the same problem - one of my projects did not make it to the deployment area (its jar). What i did is 1) remove the appliction from tomcat 2) clean tomcat work directory 3) most important: project - clean - all. Then i added the application again and... problem solved
I had the same problem in Web Dynamic project converted to Maven project.
I found error in properties->Deployment Assembly->right panel.
There was source=src folder and deploy path=WEB-INF/classes. Classes couldn't be found by Eclipse.
Changed to source=target/classes.
I have an eclipse dynamic web project, and it has some groovy files (not a grails project though, just using groovy for some small backend stuff). I have added src/main/groovy as a source folder. However, when I select "Run on Server", it copies the actual .groovy file as if it were a resource. Is there a way to fix this behavior?
I was running into the exact same issue here. I have a web project here using the following:
Eclipse Kepler
Gradle
Groovy
Spring MVC
I have a Tomcat set inside Eclipse, from the command line or from the Gradle view I can compile, assemble and generate war files, however when I try to "Run on server" the files being deployed to Tomcat are the .groovy files, not the actual .class files, even though they are successfully generated inside the build/classes/main folder
So, TO FIX this I deleted and then re-created the Tomcat server within eclipse, after doing that it was able to find and deploy the right set of files compiled by Gradle
Hope this helps
I am making web application using GWT toolkit in eclipse and my application is running successfully as we run from eclipse to right click on project and select Run as web project.
But when i make war file from eclipse-ide to Right-click on the project, pick Export, then WAR file so it does'nt work.It give me error "enter module name" it does'nt detect automatically module name. it happens only when i make a web application with gwt plugin otherwise in simple web dynamic application war file create easily with eclipse ide.i want to know how to make a war file in eclipse? And how to deploy my gwt application with tomcat server?
Thanks

Take a look to this other question: create a .war file from gwt-project
In fact the real answer will depend if you want to use ANT or Maven.
WAR files are just compressed version of your built web app projects. One simple way to make them is to use jar.exe in JDK package. That's enough to run this command after building your project in eclipse to compress those files as a WAR file:
jar -cvf name_of_jar_file.war -C /path-to-app-built-dir /path-to-put-jar-file
The best approach is to use the command
Export > Export ... > Web > War file
You will have this command on the context menu (right mouse button on the project folder) if you installed the Java tools for Web Applications. Otherwise that should you first step.
It may be the case that your GWT project doesn't show on the selector of the Web Project field, the first on on the dialogue box when you execute the command above. If this is the case you must make sure you have the Dynamic Web Module facet on you project. Select the project root project navigator and then execute
Properties > Project Facets
and check Dynamic Web Module on the right panel if it not already checked.
You should make sure that the WAR directory used by GWT is the same used by the dynamic web module. If you are not sure what is your WAR directory (probably it's the one named "war") you can go to
Properties > Google > Web Application
and read the content of the field WAR directory on the right panel.
Then make sure that the WAR directory is specified in the "Web Deployment Assembly". You need to go to
Properties > Web Deployment Assembly
and check if your WAR directory is listed there. If you war directory is "war" then you should have /war on one of the rows with the deploy
path /. Otherwise
press Add...
select Folder
press Next
select your WAR folder (e.g. war)
press Finish
If you fail to make your WAR directory part of your Web Deployment Assembly them the Export > Web > WAR command will create a WAR file, but it will lack the web.xml and all the static files on the WebContent folder, such as the HTML, images, etc.
Open your project.
Navigate to war folder.
Go to File>Export>Archive File
Export your war FOLDER as zip file.
Change your file extension form .zip to .war
Keep calm and enjoy your war file.
I'm using Eclipse Helios. I have a dynamic web project going and I've set up Eclipse to use an Ant Builder to generate a WAR file. This all works fine; if I change a .java file, Eclipse automatically runs my build.xml via Ant and updates my WAR. If I deploy the WAR to an external instance of Tomcat, it works perfectly.
However, when I tell Eclipse to run my project under Tomcat, it is not using the WAR file generated by the Ant build, or using my Ant script to generate a temporary WAR.
I know this because my build.xml script includes some additional XML configuration files in WEB-INF/classes in the WAR that are not ending up in the WEB-INF/classes dir that Eclipse pushes out.
I can't seem to find anything within Eclipse that says "when you publish, use this WAR file instead of building your own".
An alternate approach would be to tell Tomcat when it is building a WAR to do so by adding a list of files, but I can't seem to find a way to do that either.
I'm also curious how Eclipse knows what to publish since it is obviously ignoring my build.xml and my previously-generated WAR file.
Eclipse deploys a web application by looking at the Web Deployment Assembly options for your project. You can see this by right-clicking the project, choosing Properties, and then click on Deployment Assembly. Eclipse usually uses an expanded directory deployment here rather than creating and deploying a WAR (this is based on the server plugin being used, but I think most of them use an expanded directory structure for speed). If you export as a WAR it will create a WAR with the same content.
There are two main choices to do what you'd like:
Modify the Web Deployment Assembly options to match exactly what you would like in the deployed app
Don't use Eclipse's deployment; add an "External Ant Builder" to the "Builders" options for your project (right-click project, choose Properties->Builders). You can then select which targets in the ant file you want to use when eclipse builds the project. One of these options can be a deployment step
I can't seem to find anything within Eclipse that says "when you publish, use this WAR file instead of building your own".
I'm an IntelliJ user, so take this with a grain of salt. But...
Right-click on the Project Explorer target/foo.war, select Mark Deployable.
Then right-click on the foo.war file again and Run As... -> Run On Server...
Choose the JBoss instance.
If you go to the Servers view, you'll now see your WAR file under the JBoss instance as /proj_root/target/foo.war
Oh Eclipse, sigh...
