Jboss managed connection and ClassCastException

thenrick Feb 22, 2005 12:12 PM

I have a cactus test that I run with JBoss managed connection to Oracle DB and I get a ClassCastException. When I don't use JBoss managed connection the insert works fine. The insert is putting in a CLOB. I am using oracle 9.2.0.3 jdbc driver. I have JBoss 3.2.5. I would prefer to be consistent and use JBoss managed connections.
Thanks in Advance,
Tom Henricksen

You need to cast the Connection to org.jboss.resource.adapter.jdbc.WrappedConnection fist.

Then invoke the getUnderlyingConnection() method to obtain the original OracleConnection.

If you don't want to import org.jboss.* classes into your project, you could use the Reflection API to invoke the "getUnderlyingConnection" method.

You could find an example for obtaining the original Connection using the Reflection API here (Spring Framework's CVS):
