Oh that's a shame. Have been trying OpenMQ but had some probs (namely
http://forums.sun.com/thread.jspa?threadID=5377354&tstart=0) but I really
can't believe there isn't a workaround for this - ActiveMQ is held in quite
a high regard and is used quite a lot of commercial environments.

Hmm, thanks for your reply, has anyone else experienced this (and hopefully
solved it!)?
