Hi,
my previous posting is maybe to long so I try to ask again with focusing on the core problem:

1. I want to get an JCA Datasource from java: namespace (JVM locale), e.g "java:/jdbc/maindb"
2. Then I want to bind this object (an org.jboss.resource.adapter.jdbc.WrapperDataSource) again (=a second time) into the JNDI tree but this time into the global namespace.    Eg. "/globalds/maindb".

Now my problem: when doing this (the bind) I get the following exception:

What's wrong? 
I can register a dummy object (new Object()) into the global namespace without problems, it seems like the problem lies somewhere in the WrapperDatasource object, but I'm not sure.

I'm using Jboss 4.2 .0 CR1.

Thanks for you effort!!!
