I have an MDB located in domain A that needs a durable subscription to
a topic in domain B.

The way I see it there are two options.

1. Setting the MDB:s "provider-url" in weblogic-ejb-jar.xml to the IP
of the server in domain B.

2. Set up the same topic in domain A and create a jms bridge between
the two domains.

Any suggestions on which option would be preferable?
Both domains use wls7.0 sp3.
