Ralf, Tejesh, My gut feeling is that IBM has (once again ... ;-)) changed the way a TransactionManager instance can be obtained from WebSphere at runtime. Once we have established the new shiny way of doing things at IBM, it's just a matter of adding (yet) another TransactionManagerFactory instance to Castor JDO.
Regards Werner PS Websphere definitely does support JNDI lookups in general ... ;-). Whether this (still) applies to looking up a TransactionManager instance, I would not know .. ;-). Having said that, we are talking about Websphere 6, which afaik implements J2EE 1.5; I guess we should be looking at the specs as well to see whether anything has changed with regards to this matter. > -----Original Message----- > From: Ralf Joachim [mailto:[EMAIL PROTECTED] > Sent: Freitag, 05.
