Hello colleagues, I am sure someone bumped into this once before. I am trying to get an OracleConnection from Jboss pool manager and JNDI. My understanding is to get a WrappedConnection from the JNDI DataSource, I am still getting a CastException. I was wondering what is the solution around this CastException, this is the code I am using: con = ds.getConnection(); WrappedConnection wc = (WrappedConnection) con; OracleConnection ora_con = (OracleConnection)wc.getUnderlyingConnection(); Thanks.
