I'm using jboss-3.0.8 with tomcat-4.1.24. Since a couple of days we have the following problem on our production environment:
We have developed an application with one message queue. This queue receives a lot of messages (10 messages / sec). Suddenly the queue can't be reached. To see if the queue was still bound, we looked in jmx-console and the queue is still there. However when we click on the queue, to see detailed information we get the followin error:
org.apache.jasper.JasperException: RuntimeException in MBean when getting attribute 'ReceiversCount'
Does anybody knows what the problem is?
It sounds like it is broken, I'd guess the RuntimeException is an NPE?
Are there any more details about what the real error is?
Try looking further back in your log.
