Hi jboss specialists. 

I try to deploy an ear containg 1 sar 1 ejb and multible shared jars. 
I try the follwing structure of the ear: 

|--- META-INF 
| | 
| |--- application.xml 
| |--- jboss-app.xml 
|--- lib 
| | 
| |--- lib1.jar 
| |--- lib2.jar 
| |--- ..... 
|--- service.sar 
|--- ejb.jar

The service.sar also contains some jar-files which only should by loaded by the sar-classes. So the sar-file and it's packages should be loaded in seperate classloader. 
For that reason, the sar file also contains a jboss-app.xml with the following entry:

If I deploy the sar-file standalone to jboss, this works fantastic. I see in the jmx-console that a new loader-repository is created.
But if I try to pack the sar in ear, no loader-repository is created for the sar-file!!! 
So why is this entry in this way ignored?

The loader-repository entry in the jboss-app.xml of the ear does not help, because both ejb and sar should run in a different repositorys. the ejb-.jar must run in 
the ucl because it uses some libraries of the common jboss lib-path.
You are asking why everything is packed together in the same ear-file? Both (sar and ear) share libraries (in a special version) in a in the lib path, and they should only deployed once...

Thanks for help
