I've been having the same issues securing JMS Topics while granting MDB access. There is no current documentation or help out there specific to this. Based on the documentation that is available, I've tried many different configuration scenarios to try to get the jbossmq security domain setup correctly to do this, with no luck.
Can someone who understands this (ie the developer) *please* reply to the many emails posted to the forum on this subject? Does anyone know who the developer is?
