Hi I am trying to configure horneq in my server to perform JMS in my standalone.xml as per this link. https://docs.jboss.org/author/display/AS71/Messaging+configuration https://docs.jboss.org/author/display/AS71/Messaging+configuration. But I am getting the exception while starting the server. I got the following exception.

[EJB3 Development] - Memory leak by closed connections
by Rene Schneider
Rene Schneider [https://community.jboss.org/people/rschneider] created the discussion
"Memory leak by closed connections"

--------------------------------------------------------------
I found this bug (pretty sure about it being a bug, would love to directly file an issue in the issue tracker, but that doesn't seem to be possible without having some SalesForce "support case reference") when porting a real application which explicitly supports offline scenarios from JBoss 6 to 7.1.3:
When an EJB client gets disconnected from its JBoss 7 server, for example because that server has been shut down, but keeps running and eventually reconnects to the restarted server, a new org.jboss.remoting3.ConnectionImpl instance is created for that new connection. The old connection can not be garbage collected, however, as there are still two strong references lingering around to that connection in the jboss-ejb-client module. I refer to version 1.0.22.Final, which seems to be the most current final version (big difference from 1.0.11.Final, which is by default packaged in JBoss 7.1.3 - one of the code parts in which the problematic references reside has been refactored somewhere in between!)
The first reference can be found in org.jboss.ejb.client.remoting.RemotingCleanupHandler in the collection named "connections", which obviously only gets connections added to it, and NEVER removed. The second reference is similar in nature and can be found in org.jboss.ejb.client.remoting.RemotingConnectionManager in the collection "managedConnections". It is also evident from the code that connections can never be removed from that collection, not even after they were closed due to whatever circumstance.
As both of these collections seem to be used only for closing a bunch of connections at once, I devised a small fix for the problem which replaces the strong-referenced collections with WeakHashMaps. Closed connections automatically fall out of those, and connections still in use are always referenced by at least one other, strong reference. After applying that fix (and fixing another reference-to-closed-connection-bug in JBoss Remoting 3, as I described in https://community.jboss.org/message/827298#827298 https://community.jboss.org/message/827298#827298) dead connections finally were garbage collected. I attached a patch file to this posting. I'm not at all sure whether this fix is the most elegant one (okay, probably not...) but it successfully solved the problem for my application.
Steps to reproduce the issue:
- Create an EJB client and service, deploy service in JBoss7
- Have the EJB client call the service on the server frequently
- Shut down the server. The client must be built to continue calling the server, even though exceptions are now thrown.
- Restart the server. The client will reconnect and continue without errors.
- Fetch a heap dump from the client. There are now two connection objects in the heap, a closed one and an open one. Rinse and repeat for having 3,4,5,...
It is reproducible with the modules delivered within JBoss 7.1.3 as well as the newer versions of ejb-client 1.0.22.Final and remoting3 3.2.16.GA.

[JMX Development] - Deploying a .ear in domain mode (vs standalone) using remoting-jmx

"Deploying a .ear in domain mode (vs standalone) using remoting-jmx"

--------------------------------------------------------------
Hi,
In JBoss AS7,
>From a client java program,
i'm using this: service:jmx:remoting-jmx://my_host_name:port to connect to either a standalone mode server or a domain mode server.
In standalone mode:
I can retreive the MBean jboss.as:deployment=myEar.ear, and then able to deploy, redeploy, undeploy or remove myEar.ear
This works great !
However,
In domain mode:
I have 3-4 ears deployed on this server, belonging to different server groups.
There is only a few MBeans (not interesting for deploying) availables, and mainly, no jboss.as:deployment=myEar.ear available, or any MBeans related to server-groups or cluster etc...
I'm thinking that there must be a xml configuration file (domain.xml,host.xml,....) somewhere to offer the wanted MBeans ?
Why standalone mode has the jboss.as:deployment MBean and not the domain mode ?
JBoss AS7 is installed on Linux 2.6.32-279.5.2.el6.x86_64
Any idea ?

[jBPM Development] - How to auto delegate using jbpm
by Krishna Ananthoj

"How to auto delegate using jbpm"
To view the discussion, visit: https://community.jboss.org/message/818562#818562
--------------------------------------------------------------
I have a requirement where I need to auto delegate a task to a delegatee. The business requirement is to verify in the DB and find out who are the valid delegatees for the current delegator(actorId) for the current duration.
On node trigger event we need to check for the valid delegatee and auto assign/delegate this user to the task. We know that Jbpm allows us to do the delegation explicitly using delegate() method.
We have the valid delegatee information from DB at the time of node triggered but inorder to delegate the task we need to have the taskId information which is not available in this node trigger event. This is because, task object might not have been created yet.
public void delegate(*taskId*, userId, targetUserId)
We can't even use taskClaimed event method because it is not getting triggerd in case where there is single actorId specified for the node(in bpmn). It is because Jbpm directly moves the node from task 'Created' to 'Reserved' status in this case.
public void taskClaimed(TaskClaimedEvent event)
So, I dont have any idea, how to implement our requirement. Please help us.
