Hello,
I have a problem with queues (not clustered) that does not delivers messages.
I'm using jboss 5.1.0GA and messaging and remoting versions are:
jboss.messaging.providerVersion=1.4.3.GA
JBossRemoting Version 2.5.1 (Flounder)
The queue's consumers reside in a jboss4.2.3 behind a firewall.
I read some posts around here but find no solution until now.
I tried changing this immutable parameters:
<attribute name="numberOfCallRetries" isParam="true">5</attribute>
<attribute name="pingFrequency" isParam="true">30000</attribute> (to avoid the 'idle connection' firewall problem)
<attribute name="pingWindowFactor" isParam="true">71582</attribute>
<attribute name="generalizeSocketException" isParam="true">true</attribute>
By the way, the problem comes up after the queue remain 'inactive' (no new message sent to the queue) for a few hours.
When some new messages are sent to the queue someone gets delivered and someone remain in 'delivering count'.
Subsequently all the messages gets delivered with no problem as far as, again, the queue remains 'inactive' (no new message sent to the queue) for a few hours.
I have set up no unit test.
Anyone suggests to upgrade messaging to 1.4.5 ? what else ?
Regards
Leonardo

[jBPM] - jBPM 4.3 BPMN 2.0 problem

Hi there,
at the moment I am evaluating the capabilities of jBPM in combination with BPMN2.0 processes. Therefore I created a process with the academic version of Signavio and exported it as BPMN-DI (jBPM_Testprozess.bpmn.xml). Then I deleted the DI stuff because it seems not yet to be supported in jBPM. After that I adopted the Service Tasks like described in the http://docs.jboss.com/jbpm/v4/devguide/html_single/#bpmn2 developers guide bpmn2.0 section. Then I wrote a Java class with a simple echo-method to test around a bit (DbOperations.java). After that I created a UnitTest (ProcessTest.java). When I run my test I get the following exception:
org.jbpm.api.JbpmException:

The three important files are attached to this Thread. I use jBPM4.3 under Ubuntu 9.10 on Java(TM) SE Runtime Environment (build 1.6.0_20-b02).
I don't know what the exception tells me, can someone help me with that?
