I'm running a simple test application in order to figure out how I can
configure Jencks to provide a JTA Transaction Manager for XA transactions
including JDBC and JMS resources. I am using an embedded ActiveMQ broker
and an in-memory HSQL database. I am following the examples for Outbound
JMS and Outbound JDBC as shown in the Jencks sample configurations of the
source distribution. I am using Jencks 2.0, ActiveMQ 4.1.0, ActiveMQ-RA
4.1.0, TranQL 1.4-SNAPSHOT, and TranQL Connector 1.3-SNAPSHOT.
When I run my application I get the following error when I get to the point
in my code where a JMS message is being sent, right after I persist an
object using a DAO which should be enlisted in the same XA transaction. I
assume that at this point Jencks is creating the first JMS connection
because the error is happening within
ActiveMQConnectionFactory.createConnection() (line 92, "return (Connection)
manager.allocateConnection(factory, info);"). However the Connection
returned from its ConnectionManager (an instance of
org.apache.geronimo.connector.outbound.GenericConnectionManager) is a TranQL
JDBC Connection handle, org.tranql.connector.jdbc.ConnectionHandle, which
implements java.sql.Connection, and it's expecting a javax.jms.Connection
(or at least I think that's what's happening). Here's the exception stack
trace:

Does anyone have a clue as to what is going on and how I can get past this
hurdle? Thanks in advance for any ideas.
