BC4J Integration With JBOSS

I am trying to deploy an Oracle BC4J Application to JBOSS 4.2.2 GA Application Server. The problem I am having is that JBOSS uses 'Wrapped' Classes for connections, prepared statements, etc...

I have used OraclePreparedStatement and JBOSS tries to cast it into WrappedPreparedStatement which gives ClassCastException.....here's a stacktrace :

Caused by: java.lang.ClassCastException: org.jboss.resource.adapter.jdbc.WrappedPreparedStatement

Any idea would be greatly appreciated. Thanks.
