Maven EJB packaging with dependent libraries

I managed to solve the problem. It seems that these libraries has to be packaged within /lib directory and not in root of EAR. Adding defaultLibBundleDir element solved the problem.

E.g.:

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-ear-plugin</artifactId>
                <version>2.6</version>
                <configuration>
                    <defaultLibBundleDir>lib</defaultLibBundleDir>
...

Did you leave the <addClasspath>true</addClasspath> on the EJB config?

Well, you can leave it like this, but you'll get a heap of log entries (WARN) on server start complaining about the classpath entries. I prefer to set it to false. <addClasspath>false</addClasspath>
