Summary: onMessage() does not get activated

Initial Comment:
Hi there,

i wrote a litle programm to comunicate each other. =

(Something like a chat) when I start the openJMS =

server, then start the so called client on the same =

machine, it works finde. I can send messages an other =

client (on the same machine) get it. There onMessage =

method awakes an is doing its job.

But when the OpenJMS server is on an other machine, =

far away on the internet or next to me using a cros-link-
cable, it does not work. I can send messages but =

onMessage() never awakes. =

So I put a test-recieve button to the panel. ( a of =

course had to delete the messega listener) When i now =

send a message, the onMessage() method does no not =

do anything (of course) but when i use the recieve =

button (mytopic.recieve()) i get the message e sent.

what is the problem? i can=B4t imagine that OpenJMS =

can=B4t communicate over a network. Do i have to start =

something, could i do anything wrong when using an =

external server as a local server?

I am getting the same problem, even with two machines on =

the same local network.  Everything works when OpenJMS and =

the client apps are running on the same machine, but no =

messages appear to be received and processed when the =

receiver that has the MessageListener is moved to a =

different machine.

When I browse the queue with Hermes I can see that the same =

number of messages that I have MessageListeners for have =

disappeared off the queue. i.e. if I create and register =

10  MessageListeners, then 10 messages disappear from the =

queue. When I kill the receiving process, the ten messages =

come back again.

I am running OpenJMS 0.7.7 alpha 3.

You might be having firewall problems. If you are using the =

rmi connector, the server needs to open a connection back to =

the client, which may fail if the client is behind a firewall.
If so, try using the tcp connector.

Re-open this (or better yet, discuss the problem on the =

openjms-user list) if you have any issues.
