Hi,
I am very new to JMS and was just trying to run a few programs to check out=
the features it has. I have 2 classes for implementing Publisher and Durab=
le Subscriber with MessageListener. When I try to publish the messages, it =
publishes them successfully to the topic. But the problem is when I try to =
start the subscriber, it hangs and is never able to read the messages. Even=
the onMessage() method of MessageListener is not invoked. When I modify on=
ly the publisher code to have CLIENT_ACKNOWLEDGE instead of AUTO_ACKNOWLEDG=
E in Session, the subscriber starts and is able to read for the first time.=
But next time after a new message is published, again the subscriber hangs=
and is unable to read any messages.
Can anyone please help in this matter as it is very urgent? I am attaching =
my programs with this email.
Regards,
Anupam
