Hi,

just knocked together a proof of concept for a generic j2ee deployment style for 
maven.  As this is a proof of concept, I've only completed basic war deployment 
/ undeployment.

What I have done is added a few target to plugins/j2ee/build.xml which delegate 
to a specific appserver/build.xml.  These targets enable deployment, 
undeployment and updating of a war file within tomcat(4.1 dev) and 
weblogic(6.x).  To switch between servers (tomcat | weblogic) change the 
maven.j2ee.server property in j2ee/build.properties

Requirements
Ant 1.5 (for the serverdeploy tasks)
(either or both of the following)
Tomcat 4.1 (for the org.apache.catatlina.ant tasks)
Weblogic 6.x

this is what's in the j2ee.zip

       |_ j2ee
         |_ build.xml                contains a few new targets
         |_ default.properties       contains one new property
         |
         |_ tomcat
         | |_ build.xml
         | |_ default.properties
         |
         |_ weblogic
         | |_ build.xml
         | |_ default.properties

unzip j2ee.zip under maven.home/plugins
modify maven.home/plugins/j2ee/tomcat/default.properties for your tomcat props.
modify maven.home/plugins/j2ee/weblogic/default.properties for your weblogic props.

examplewar.zip contains a maven project that when deployed has a servlet 
listening on /examplewar/TestServlet

unzip examplewar.zip somewhere and then execute these targets

examplewar>ant maven:war-deploy
examplewar>ant maven:war-update
examplewar>ant maven:war-undeploy

Both tomcat ant weblogic need to be installed locally to access the jars.  The 
tomcat classes (contained in tomcat-home/server/lib/catalina-ant.jar) facilitate 
deployment via http to remote servers, so would work as a jar in librepo.  AFAIK 
the weblogic classes send the file location of the component to the server which 
uploads the file from the filesystem. So weblogic has to be installed on the 
same filesystem as the maven deployment :(

Let me know if this is a good idea and I'll do deployment for ejbs, ears etc.. 
and add a few other app servers.

Cheers
Nathan
