Topic type is of one to multiple model. Wonder if any constrain on hownmany producers can be involved in one topic.

Alsothere is property file mentioned in the jms tutorial, jms_client.properties. there was no words on it. Can anyone give some explanation, example?

Both queues and topics can have many producers. JMS does not define a limit, though obviously it will not be infinite.

Which tutorial are you looking at? I suspect you're looking at a very old version of the tutorial; jms_client.properties is part of the J2EE 1.3 SDK, which is dated 2002.

The most recent JMS tutorial is in the Java EE 6 tutorial
http://docs.oracle.com/javaee/6/tutorial/doc/bncdq.html
which should work with the latest version of GlassFish
