[...] for a Maven ready EJB3 ready to run project? I came across this post. I gathered all the good ideas and grouped them together in ejb3-maven Google Code [...]

That is indeed correct.
I would also like to note that with the coming of EJB 3.1 (Lite) creating this whole structure is no longer necessary.
Next to that I would like to point out that Netbeans (6.8) can create these XML files for you when you create a new maven web project. Have a look at it if you like to see what it looks like.

Hi, thanks for the tutorial. One world, should the artifactId of the main pom not be ‘ejb-sample’ ?

Best

Sorry for my late response:

The piece of xml in the maven-ear-plugin should take care of generating the required descriptor (in this case for jboss). For deploying you might also want to take a look at the maven cargo plugin.

ok guys…thanks for such a nice article clears up a lot of things…i have another question though…

I followed the article and have 3 dirs ejb/war/ear… ear is getting generated nice and well (i have removed the jboss specific stuff i just want a clean ear).

and after that I do a
mvn eclipse:clean eclipse:m2eclipse
on the root pom.xml and i get a nice eclipse ready project.

but when i try to add the ear to the server (jboss server from within eclipse)I get a message saying that none of the projects can be added to the server.

As far as i can figure … it seems you need to generate some sort of application descriptor from within eclipse to help eclipse recognize that out of those projects one is an ear project and should be added.

any thoughts around this guys…

Asif..

Is there a way I can generate stubs for the ejb (EJB 3) to be used by a client.
Is there a maven 2 plugin for it? Has someone ever dealt with this? I do not see any way to do it.

Check this out: http://code.google.com/p/javaee5-maven-archetype/

archetype generating similar structure (in the war module jsf 1.2 is included).

Configuration for maven-ejb-plugin should be changed like this:

org.apache.maven.plugins
maven-ejb-plugin

3.0

true

Otherwise, JBoss throws java.lang.NoClassDefFoundError, when using 3rd party libraries.

Hi,

I think you can use the JBoss repository (http://repository.jboss.com/maven2) for the EJB dependency:

javax.ejb
ejb-api
3.0
