merging two war files with overlays - maven

Question

I have to merge two war files. I use eclipse indigo and maven 2. So I put one war as a dependency in the others pom.xml and added the overlay option as well:
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.2</version>
<configuration>
<overlays>
<overlay>
<groupId>org.mydomain</groupId>
<artifactId>myproject</artifactId>
</overlay>
</overlays>
...
I use this to add all dependencies as jar's to my lib folder:
...
</configuration>
</plugin>
<plugin>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
<outputDirectory>${project.build.directory}/webapp/WEB-INF/lib</outputDirectory>
</configuration>
</plugin>
...
So if I perform maven install a proper war file is build with everything in it. The problem is when I deploy this on the glassfish server (3.1) there are no classes deployed (I looked in the eclipseApps folder in my glassfish folder). The jar's are there, the folders are there but empty. So it does not work on the server.
Anyone an idea?
Update:
As proposed in the comments I put the war file in the autodeploy folder and got the following errors:
