Exception in createStatement when using UserTransactions

Question

I am trying to use UserTransactions in Weblogic. After obtaining and starting a transaction, I get the connection object. I am getting an error when I try to use connection.createStatement. The code and exception are below:
The database is Oracle 9i.
Code:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
env.put(Context.PROVIDER_URL, getWebLogicProviderUrl());
initialContext = new InitialContext(env);
UserTransaction tx=(UserTransaction)initialContext.lookup("javax.transaction.UserTrasanction);
tx.begin();
DataSource ds = (DataSource)getInitialContext().lookup(dataSource);
Connection connection=ds.getConnection();
Statement stmt=connection.createStatement();
At the above line I get the following exception:
java.sql.SQLException: weblogic.rmi.extensions.RemoteRuntimeException: Unexpected Exception - with nested exception:
[java.rmi.MarshalException: error marshalling return; nested exception is:
     java.io.NotSerializableException: oracle.jdbc.driver.T4CConnection]
     at weblogic.jdbc.rmi.SerialConnection.createStatement(SerialConnection.java:168)
     at com.fedex.edm.updateapi.server.EdmUpdateSBO.deleteShipmentDoc(EdmUpdateSBO.java:962)
If there is another way to implement to transaction mechanism please provide sample code.
Thanks.

Answer 1

Seems like a problem with the library.
How about getting the source code for it and checking out that line 559 to see what causes the null and whether you can do anything about it. If not, then file a bug report about the lib.
