jboss xa datasource

When I started creating jboss XA datasource , i started getting errors like Class Not Found 'org.jboss.resource.adapter.jdbc.vendor.OracleXAExceptionFormatter'.

I found the problem , we should use exact file oracle-xa-ds.xml format as specified in jboss-as/docs/examples/jca directory .

When I was missing
Oracle9i
I was getting NoClassFoundError , but as soon as i added metadata type mapping then it worked fine.

I guess jboss should have given some better error message instead of failing in NoClassFoundError , weird.

I used metadata with Oracle 11g and it worked fine.
Thanks
