Hello. I am trying to use Active MQ 4.1 to create applet, which listen JMS
messages. I have several pages with this applet. When applet starts it
creates connection, topic, session and subscriber. When applet stops, it
closes them. However, when I open and close web pages, where applet
presents, IllegalStateException occurs.
Exception in thread "ActiveMQ Transport: tcp:///127.0.0.2:61616"
java.lang.IllegalStateException: Timer already cancelled.

And then:

his wire format.

After that applet can not receive any message, even if connection reopened.
Please help.
