How to package EJB3 with external domain-jar

Question

Hello again :)

I am facing another problem in my little test-webapp. I have an EJB module (created via maven-pom) that basically wraps the data-access, so all it does is some DAOs implemented as Stateless-SessionBeans. My domain-model (simple POJOs with JPA2 annotations) is located in another, simple java, project that will be packaged as jar-file.

When I create the enterprise-archive, maven only puts the webapp and the ejb-module into the application.xml and even when I change this manually the ejb-module cannot find the classes from the domain-module at deployment time.

I read something about that an ejb has to have all its dependent jars within its own archive but I cant believe that since this domain-module is used by other projects as well.

How would I package this (or set it up in maven) so my ejb can load classes from an external jar?

thanks

If I remember well, simply generate a manifest with a Class-Path entry in your EJB-JAR:

<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-ejb-plugin</artifactId>
    <configuration>
      <ejbVersion>3.0</ejbVersion>
      <archive>
        <manifest>
          <addClasspath>true</addClasspath>
        </manifest>
      </archive>
    </configuration>
  </plugin>
  ...
</plugins>

And add your external jars to the EAR. To do so, declare them as jarModule in the Maven EAR plugin configuration. See modules configuration.
