[jboss-user] [JNDI/Naming/Network] - NullPointerException while binding jca pool vom java: namesp

Hello, for JUnit testing purposes I need to access JCA Connections from a different JVM. Since it's not recommended to put JCA Datasources in the global JNDI context, they are in the java: context, which means they ain't reachable by JUnit JVM. My idea now was to bind the datasources which are in the java: jndi context to global context with the name comp/env (like a tunnel). When I access the database from JUnit from a different JVM, the "java:" is ignored and I get the correct datasource. (Of course this is only done in a development environment.) Example: (global ctx) comp/env/testdb -----------> java:/mydatasources/testdb Unfortunately I'm having problems while binding the WrapperDatasource from the java: ctx to the global ctx. I'm getting the following NullPointerException Maybe this is not allowed? I'm having no problems in binding dummy objects into to the global ctx. | | 10:25:33,593 INFO [STDOUT] bound maindb to pseudo context (for JUnit) | 10:25:33,594 INFO [STDOUT] name: maindb |
