Ant help us to build and deploy applications, but how to debug application in the Application server?
Could you please help me to debug the EAR file created with Ant build?
(I have imported the EAR file in to Eclipse to debug using Eclipse, I am able to run the project successfully, but when I start debug after setting a breakpoint it reports as Source not found, please help me to resolve this issue)
You have to not only "import" your EAR file (containing compiled bytecode) but also your source code files. If you import the EAR as a "referenced library" you may edit the library with alt-enter, and add the path/jar of the sources.
How do you start & publish in eclipse anyways?

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 am newbie to GWT. I have built gwt maven project. To run in development mode, I first compiled project Google|Compile Project, then from command mvn gwt:run, it runs fine on
http://localhost:8888/index.html?gwt.codesvr=127.0.0.1:9997
but for production I want to access module
http://localhost:8888/index.html
When I omit gwt.codesvr= argument, I am getting error "gwt module may need to be recompiled". After Recompiling, I get the same error. Any help/pointer?
Thanks,
i run gwt project on tomcat on production mode. Jetty cant show it. Try to tun with external web module. When you are look at the IDE console title show us 'Development Mode'. Tyr with external , in any exception i can help.
You did it correctly, but as the error states, the module needs to be re-compiled (GWT Compiled). Once recompiled, Force your browser to reload (Ctrl + F5). If that doesn't work, you can look at this answer I wrote regarding cleanup of compiled output. Do what's listed there, and try running GWT compile again.
To run production mode outside Eclipse, you must do a GWT compile and create a WAR file, which you can then deploy on a Java application server such as Tomcat. This process is much easier with an ant build script.
To make an ant build script for your project:
You can easily create an ant build script by running the webAppCreator command from the directory where the GWT library is installed. That command will create a sample project just like clicking "New Web Application Project" in Eclipse, except it will also make a build.xml file.
You can run it in Eclipse by right clicking build.xml > Run As... > Ant build. By default it will run the build target. It also has a war target, which you can run to create a WAR file.
For more details on the webAppCreator, look here.
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 very new to gwt and in fact I don t really understand it.
I have a web project that had already been developped. I just want to change the toolbar that requires gwt in a RichTextToolbar.java file. So I downloaded Eclipse and its gwt plugin.
In a precedent question, I had the answer that I should take thes only file RichTextToolbar from my php/html directory, put in the src folder of my eclipse web application project; then run it and finally taking back the compiled files from the war folder and put it in my php/html directory.
Now, the problem is that when I debug or run the files in eclipse, I am told to choose ant. And then I have a message that no build.xml file is found. Could anyone help?
Best,
Newben
If your intention is to compile the Java code in GWT to Javascript, then you can use 'Compile GWT Project' option under GWT menu in Eclipse.
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...
