--------------------------------------------------------------
I am getting the exception "java.lang.UnsupportedOperationException: Destination not specified" in the MDB. The MDB is set to send a reply as and when a message arrives. I am sending 5 messages from he client program.
And in the server log I am able to see 5 messages with proper destination. But the client program is receiving only 2 messages as reply & the above exception is shown in the server log.
Can anyone help please?

Hi All,
We are facing frequent OOM issue in Production SOA server instances.
we have configured the JVM arug like below Is this the correct configuration or else any thing we need to add avoid frequent OOM error.
/usr/java/latest/bin/java -Dprogram.name=run.sh -server -Xms4096m -Xmx4096m -XX:PermSize=256m -XX:MaxPermSize=512m
Below restarting the server i have taken the Heap history.
Heap Configuration:
MinHeapFreeRatio = 40
MaxHeapFreeRatio = 70

MaxNewSize = 17592186044415 MB
OldSize = 5439488 (5.1875MB)
NewRatio = 2
SurvivorRatio = 8
PermSize = 268435456 (256.0MB)

I suspect some generation ration configuration is worng, Could you please correct me if am wrong.

I am having difficulty with defining Service Tasks for the BPMN editor for Eclipse. I believe there is some form of conflict between the BPMN editor plugin, and something else in my Eclipse. We use a standard bundle of plugins for the development team, to ensure we are all using common versions of necessary plugins such as m2eclipse, and subclipse.
I have downloaded the 5.2 installer, and run the ant task "install.droolsjbpm-eclipse.into.eclipse" task, and the editor appears to be installed, with the ability to create a new bpmn process appearing as expected from the documentation. However, when I attempt to define a Service Task, following the directions in Chapter 13 of the User Guide, the editor gives me an error when starting up, which says: *Could not parse work definitions test.wid: java.util.HashMap cannot be cast to java.util.List*
There is a stack trace in my eclipse log file, as well:
!ENTRY org.drools.eclipse 4 120 2012-02-08 12:39:17.635

I have also used the installer to download and install a full clean eclipse package using the install.demo.eclipse target, and the definition works as expected, there. This confirms that the .wid file itself is valid. However, that install is missing all of the other plugins needed for development in our standard development.
I am using Eclipse Helios, with m2eclipse 0.12, subclipse 1.6.17. Any assistance in making this work in our standard environment would be greatly appreciated.

Hello -
I've been wrestling with this for about a day and a half, now. My environment is jBPM 5.2.0.Final, running on JBoss 5.1.0.GA, with Java 1.5.0_12, under 64-bit Windows 7. It's entirely possible that I am missing some portion of configuration, but I'm not able to determine what it is, exactly, that I'm missing.
I am attempting to create a new StatefulKnowledgeSession, and start a process with it, using the JPAKnowledgeService, as described in the documentation. The code I am using to do this is as follows:
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("ImmunizationProcess.bpmn"), ResourceType.BPMN2);
kbuilder.add(ResourceFactory.newClassPathResource("SchoolFormProcess.bpmn"), ResourceType.BPMN2);
kbuilder.add(ResourceFactory.newClassPathResource("LegacySubscriptionProcess.bpmn"), ResourceType.BPMN2);
kbuilder.add(ResourceFactory.newClassPathResource("SubscriptionMasterProcess.bpmn"), ResourceType.BPMN2);
kBase = kbuilder.newKnowledgeBase();
// create the entity manager factory and register it in the environment
EntityManagerFactory emf = Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" );
env = KnowledgeBaseFactory.newEnvironment();
env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );
env.set( EnvironmentName.TRANSACTION_MANAGER, jtaManager);
kSession = JPAKnowledgeService.newStatefulKnowledgeSession( kBase, null, env );
When it reaches this last line, it throws an InvocationTargetException, which I've managed to narrow down to the constructor call on SingleSessionCommandService, which appears to not exist:
Caused by: java.lang.reflect.InvocationTargetException
at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39)

at java.lang.reflect.Constructor.newInstance(Constructor.java:494)
at org.drools.persistence.jpa.KnowledgeStoreServiceImpl.buildCommandService(KnowledgeStoreServiceImpl.java:129)
... 85 more
The persistence.xml I've put in place for the JPA persistence looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

Any and all help would be appreciated, and I can provide additional information if needed.
