Problem with WAS 3.5.5 Naming Service

[Michael Kästner]

I run into a problem using the naming service of WAS 3.5.5: A session bean
is contacting the WAS naming service by establishing it's initial context
sucessfully. The reference that needs to be looked up relates to a JMS
QueueConnectionFactory of IBM MQSeries (MQQueueConnectionFactory). During
the context's lookup-method a NoClassDefFoundError (please refer appserver
stderr-output below) occurres, indicating that the superclass
"javax.jms.ConnectionFactory" could not be found - even if I alredy loaded
this class successfully before the lookup-line of the EJB.

Thank for your cooperation.

Kind regards,

Michael Kaestner
