Nils,
I presume the two Glassfish instances weren't clustered. If they were, the two would exchange messages without the need
for further configuration.
If the instances are not clustered, there are several ways to configure Glassfish to send messages to a different
instance. Here is one simple way:
Sending:
If you want a JMS connection in one instance to send to a MQ broker running in another instance, you need to configure
the addressList property of the connection factory to refer to the other MQ broker.

Receiving:
If you want a MDB in one instance to consume messages from a MQ broker running in another instance, you need to
configure the addressList property of its activation spec to refer to the other MQ broker.
http://docs.sun.com/app/docs/doc/820-6740/aeooq?a=view
Format of addressList:
The format of addressList is a URL something like mq://host:port
where "host" is the hostname on which the other instance is running, and "port" is the JMS port it is using. The port is
probably 7676 for a standalone Glassfish instance.
You may see a INFO message when the other instance is started, of the form "JMS Service Connection URL is..." which
should tell you what addressList to use.

P.S. I suspect fetching a connection factory from the other instance won't help, since by default a connection factory
will probably refer to localhost.
