JMS subscriber (applet) stops receiving messages
I have an applet that subscribes to a JMS queue. Messages are published very infrequently, about once every 6 hours. I've found that the applet stops receiving messages unless it is run on the same machine as the JMS server. The applet will stop receiving messages after a relatively short period of time (maybe 30 minutes +/- 20 minutes).
The applet receives no notification the connection has failed. The server log has a "Connection reset" error.
Everything works fine if I run the applet on the same machine as the JMS server.
1) Is this a configuration problem? Is there some sort of keep-alive I have to configure?
2) Why doesn't the subscriber receive any sort of disconnect exception?
I'm using JBoss 3.2.2RC2.
I attached parts the log from the JMS server below. I'm not sure why there is an OIL connection failure in there - I'm using a UIL connection factory. (The second exception is the UIL stacktrace).
