Simple JOTM Questions

I'm starting to use JOTM and have a few simple questions:

• If I start an embedded JOTM instance, can I perform a 2 phase commit between a remote database (with an XA enabled driver) and a local JMS queue initiated by a 3rd party client开发者_高级运维?
• Does my JOTM instance require both the Database and JMS provider .jar files on the classpath if a remote client is performing the transaction or only if the transaction is initiated via a local client?

Regards,
