I was wondering if it is possible to make a Java EE application being managed by Maven and automatically deploy it to JBoss all from Eclipse. To my knowledge I current right click on my project and select "Make install". After that completes, I open the server pane and right click on my deployed ear and either select "Full Publish" or "Incremental Publish". Is there a way to condense these actions into one click? I tried to write a windows batch file but I didn't have much luck with that, and it would only work for our devs working on Windows machines. I know I can make run configurations but when I try to make one it is very intimidating and I get frustrated and give up.
Thanks for your help!
You can use JBoss Tools 3.3.0 (Current milestone M4) with the maven integration to easily deploy projects (wars or ears) to your AS7 server.
Once you defined your AS7 instance in eclipse, all you have to do is right click on your project > Run As ...> Run on Server. It'll start your app server if it's stopped, or just deploy your app if it's already running.
See http://vimeo.com/25768303
and http://community.jboss.org/en/tools/blog/2011/11/09/jboss-tools-shift-happens-in-m4
If you are using maven, you can use the cargo plugin: http://cargo.codehaus.org/Maven2+plugin
You just configure where the JBoss is installed, set the plugin to run in the phase you want (or make a new one) and you are all set.
You can also create different configurations for different profiles, so you have local, integration, test, production, etc... And just by running with the selected profile deploys the ear in the server, remote or local.
If you want more control, you can set the path of the container as a variable that you pass in the Eclipse run configuration, that way each developer can have their servers in different paths.

The deployment we follow is that we use runAssembler.bat to build an ear file and deploy it in a app server. We are using weblogic and jboss for testing purposes of the modules we built. However for every small change, we need to run runAssembler and build a new ear and deploy it in app server and restart the server.
I would like to find out if anyone figured out a way to do Hotswapping of class files which are generated by the code we write in ATG environment in either weblogic or jboss.
By attaching your IDE to your Application server on the Debug port it is generally possible to do hotswapping. Setting this up on Eclipse and JBoss is documented here, here and here. There is some information for setting it up in WebLogic here.
Attach your debugger, edit the java file, click 'save' and with hot code replacement in your IDE it should now update the running class file. In Eclipse it usually gives a popup if it was unable to do the sync. If you are using Eclipse, make sure the 'Build Automatically' flag under projects is ticked or you'll be waiting forever. I've not had any issues doing this via JBOSS (exploded ATG EAR) and variable success in doing this on WebSphere 7. It may also be prudent to make sure the same JAVAC you use to compile your build is the one loaded into your IDE compile path.
Another way to at least reduce the build/deploy time would be to deploy an unpacked/exploded EAR and simply copy your class files across (you could use the Eclipse FileSync plugin) and restart the server.
There are also some commercial options available, like JRebel
In our organization, we had good success in using DCEVM. It simply patches your JDK (in Windows: jvm.dll).
Download and patch your JDK
Launch your JBoss/Weblogic with the patched JDK
Set up Eclipse's Installed JRE's to point to patched JDK (restart and rebuild once)
Start the server, Launch debugger and connect
Ensure Eclipse's Debug view shows "Dynamic Code Evolution VM" (instead of something like "HotSpot VM")
Change your code, and voila!
You can do this with JRebel. After hotswapping you don't need to restart the server, only reload you deployment from Weblogic.
When I start the glassfish server I have noted that it loads all the previous projects that i have developed and previously deployed.
I think that somewhere there is a config file that tells the server to reload the projects, but if i would like to work just on one of them what i have to do?
i suppose that i have to change or delete some entry in a glassfish configuration file, but i don't know where it is and how to do that.
thanks
Massimo
You have different options.
You can go to the Glassfish admin GUI via http://localhost:4848 and look under "Applications". You can undeploy properly deployed applications there.
If this is not working you can manually delete the applications from the glassfish folder: Look at
/[glassfish_installation_path]/glassfish/domains/[your_domain]/applications
or
/[glassfish_installation_path]/glassfish/domains/[your_domain]/autodeploy
Glassfish is running applications in these folders at startup time.
The undeployment depends somehow on the method you used to deploy the applications...if you used NetBeans to deploy you can probably even select the application in NetBeans and click "Clean and build" do undeploy it.
Environment
Win7
Eclipse Helios, Eclipse 3.6.1
Java 6
Jboss Tools version 1.0.0.v20110123-0129-H10-CR1 from the nightly builds
Jboss 4.2.3
In the past I used MyEclipse, which is a paid tool. In myEclipse, it's easy to configure a JBOSS Server and then deploy
your webproject in it. While in debug mode, if I change a java class (OR JSP), its changes are immediately reflected under Jboss and
I can test that change, without doing any explicit redeployment
So myeclipse had these features working outof the box....
I'm trying to accomplish same functionality with Eclipse Helios and Jboss Tools
Case 1
I added the Jboss Server via Java EE perspective->Add Server etc...
And then added my WebProject to this Jboss Server
When I right click on this added project and publish from here, it runs an ant script, to create a single (Standard) war file...and it always does the whole thing over.
I dont get a choice to deploy it expanded and anything to specify an incremental deployment
Case 2
Since Case 1 didnt allow exploded war and anything incremental, I decided to use JBOSS Tools
So I opened, Window->Show View->Other->Jboss Tools->Project archives
Selected my webproject, after which it showed up in the "Project archives" tab
So then....Right click on the project name in "project archives" tab.....->New Archive->WAR...and I added my project to deploy in exploded form. ok.
Now if I right click on the added WAR and click "Build Archive (full)"....it deploys the whole web project. Everytime it does the whole thing, instead of incremental.
Since that option didnt do it incrementally, so I right clicked and clicked "Publish to Server". The window that pops up, doesnt show me any servers...from where do i add to this?
In summary....
A) I havent seen any way to incrementally deploy
B) When I'm in debug mode, my java file changes dont reflect immediately...I dont mind redeploying, but since its not incremental, its annoying to do the whole thing over and over.
So question is ...
1) How do I do an incremental deployment?
2) How do I configure this, such that my changes in java classes are reflected immediately when in debug mode.
btw I have seen people suggest an alternate soln to use a custom ANT script....But will ANT script incrementally deploy, if I use it's copy command?
Thanks

It's MUCH simpler than this.
Forget about JBoss tools Archives, simply use the WTP adapter that JBoss tools provides. This one does incremental deployment (like MyEclipse).
Make sure you install JBossAS Tools from JBoss tools (yes the name sucks). Its description is:
Provides a WTP adapter for JBoss AS 4.x and 5.x. Supports incremental and exploded deployment.
Dish the WTP Server adaptor you created earlier from "Add Server etc..." and do it again, but this time don't choose from "JBoss" but choose from the new folder "JBoss Community". You'll see several new adapters there with the red logo and a slightly different name (e.g. WTP bundled is JBoss v5.0 but the one supplied by JBossAS Tools is JBoss AS 5.0).
Alternatively you can also use JRebel, which does incremental deployment no matter what WTP adapter you use (you disable the automatic deployment in that case).
Im new to Eclipse. I use Tomcat as my run time server, but every time I modified the jsp pages, Eclipse was still displaying the older one. Just wondering how to redeploy the application so the changes can be reflected.

Doubleclick the server instance in question in the Servers view to open its configuration. Now, in the right top you should see a section called Publishing. Open it to verify and configure autopublishing settings.
Eclipse should do that automatically for you.
Otherwise, on the Servers view (Menu Window->Show View->Servers), you can right click on your Tomcat instance and hit "Publish" or "Restart"
Make sure you have the "JST Server Adapters" ("Web, XML and Java EE Development category") feature installed.
Eclipse's publishing functionality requries the project to be a "web project", and in some cases requires additional configurations.
Go to Windows > Preferences > Server > Runtime environments and add your tomcat
Either try using publishing, or (better I think) use the FileSync plugin. There you can tell which folders from your project should be copied (live) to what directory on your machine (the tomcat/webapps/yourapp). With a little more effort the filesync configuration can be made machine independent (only using one parameter as TOMCAT_ROOT), in case you want to check-in the project to a repository where others will use it.
Get the Tomcat plugin. It was nice because you can install Tomcat on your system and then associate your web app with that instance of Tomcat. The plugin will let you stop/start Tomcat and define a server such that when you do a build it knows how to deploy the changes. There may be some newer plugin but the Tomcat plugin worked for me and was fairly simple to install and use. Here is a page from IBM on using Eclipse and Tomcat. Inside that page it points you to the following: http://www.ibm.com/developerworks/opensource/library/os-eclipse-tomcat/
I'm developing on a Ubuntu 8.04 machine using Eclipse Ganymede. I installed Tomcat 5.5 using sudo apt-get install tomcat5.5 tomcat5.5-admin and using an Ant script I deploy my WAR file by copying it to $CATALINA_HOME/webapps.
I then created an Eclipse project and I have it output compiled source in a similar but separate directory structure under $PROJECT_ROOT/target/. I still deploy the WAR file by right clicking on the build.xml and choosing my deploy-war task.
As Tomcat is running as a deamon, automatically started up on booting, I'm not instructing it when to start or exit.
My problems with this setup are:
Using this approach I do not get any output to the Eclipse console, as Tomcat is running under the tomcat55 user and I have a different login and no access to Stdout of tomcat55.
The logging which occurs is also directed to Stdout at the moment, which I find pretty nice during development. But it's not nice when I can't see it. :-)
I don't have any servers under the Server tab and no Run configurations. This makes it impossible for me to use the Debug mode of Eclipse, which otherwise is quite convenient.
What do you think I should do to integrate them and in turn make my development environment much better?
I'd say forget the pre-packaged Tomcat. Grab the apache-tomcat-x.y.z.zip from the site, unzip it somewhere in your $HOME and add a Server to your eclipse workspace, pointing to your local installation of tomcat. Of course you need the j2ee/wtp Eclipse bundle. Works fine on Windows, can't see a reason for it not working on Linux.
Edit: You may have to fiddle with server ports if you have two tomcat installs.
Add Tomcat to the list of Eclipse servers and run your web-app on the server. If you need more details click here.
I never cared about 1 and 2, so I can't really help you with them.
regarding 3:
You don't need any servers under the server tab for debugging to work. Just start tomcat with these environment variables
export JPDA_ADDRESS=8000
export JPDA_TRANSPORT=dt_socket
and configure eclipse accordingly: run - open debug dialog - select remote java app and create a new configuration.
You need eclipse to manage a copy of tomcat, then it can debug it. The clue to the problem was that you have to push deploy-war, this means the files are leaving your development environment and entering an external server. On a properly configured development environment, you only need to save your java file, it will auto-compile and already be on the local tomcat install, which might try to auto reload the web-app, and you can refresh your browser without reloading anything on the server. Look up some more tomcat plugins, there are a few different ways to do this.
If you want to do regular debugging and relaunching of Tomcat apps, you might want to take a look at MyEclipse - it can make things a lot easier.
