I'm a bit confused by the line in _amq.js that initiates the long poll to the
server (Jetty 6.1.4 using continuations in my particular case.)
_startPolling : function() {
if (amq.poll)
new Ajax.Request(amq.uri, {
method: 'get',
parameters: 'timeout=0',
onSuccess: amq._pollHandler });
}
Tracing the code into MessageListenerServlet, it seems like this request
would cause an infinite wait to occur when continuation.suspend(timeout); is
reached. A timeout value of 0 implies an infinite wait.
I see the infinite wait when I run the Jetty 6.1.4 and ActiveMQ 5 SNAPSHOT
from my IDE, however when I run the activemq-web-demo module using maven,
the get request with a timeout of 0 returns immediately with an envelope
with no messages.
I'm confused by the different behaviors, and I can only debug into the code
that I launch from inside my IDE. I'm not sure how to remote debug from a
maven-launched app, but I will continue to look into this.
Any thoughts?
