No - there is just 1 domain. It doesn't matter what transport,
protocol or client you use.

I'm afraid you are mistaken :)

The most likely reason is mismatch in the JMS destination names and
the ones used in the Stomp protocol. The quickest way to disagnose the
issue is to start with queues, then use the JMX console to look at the
destination names being used by Java and Perl clients to check you've
got the naming conventions correct etc.
