Dear All,
We are using:
JBoss EAP 4.3.0GA_CP08
JBoss Remoting 2.2.3.SP2-brew
JBoss Messaging 1.4.0.SP3_CP10-brew
We have an application that receives notification using JMS Topics. One of our QA testers has noticed that if the client is left up over night the client seems to stop receiving notifications.
We see the following 'control connection' warning on the client:
2011-06-01 14:56:39,835 WARN 2011-06-01 09:34:16,199 WARN org.jboss.remoting.transport.bisocket.BisocketServerInvoker$ControlMonitorTimerTask@12a9dc0: detected failure on control connection Thread[control: fdfc58[SSL_RSA_WITH_RC4_128_MD5: Socket[addr=/10.90.7.1,port=4458,localport=3823]],5,] (5c4o02a-q8t994-god83ybh-1-god83yyh-b: requesting new control connection
We see the marshalling error on the server side due to a java.io.IOException: Connection timed out error:

Hi Ron,
I am observing similar issue in my application. We are using Jboss 4.2.0.GA, Jboss Remoting 2.5.3.SP1
We have a firewall between our server and client and we followed the forum,
http://blog.akquinet.de/2009/09/30/using-jboss-messaging-in-a-firewalled-... http://blog.akquinet.de/2009/09/30/using-jboss-messaging-in-a-firewalled-...
to set our parameters like below,

+ <attribute name="numberOfRetries" isParam="true">10</attribute>+
+ <attribute name="JBM_clientMaxPoolSize" isParam="true">200</attribute>+
+ <attribute name="callbackTimeout">10000</attribute>+
+ <attribute name="secondaryBindPort">4481</attribute>+
With this implementation, we have mulitple Connections in CLOSE_WAIT state most of them getting cleared and some left behind.
After several days, we loose the JMS communication. We need to restart the application again to get rid off.
Also we observed the below exception multiple times when the issue happens,
Exception:
2011-03-28 11:50:10,271 TRACE [org.jboss.remoting.transport.socket.ServerThread(638)](WorkerThread#4[10.255.254.134:42933]) WorkerThread#4[10.255.254.134:42933] EOFException received. This is likely due to client finishing communication.
java.io.EOFException

at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:586)
at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:234)
Kindly share some light to resolve this.
Regards,
Joseph.

[jBPM] - Tasks Assigned to Groups Not Found

"Tasks Assigned to Groups Not Found"

--------------------------------------------------------------
Hi,
I'm using JBPM 5.1 Final and have spent a couple of hours learning how tasks are returned from the TaskService. I believe I have found a bug in the way tasks are returned when they are not assigned to a particular user.
I have 2 simple processes that I'm using to test my code. I'm making sure I can create a process and then return the first tasks from them.
The first one SimpleHumanTaskProcess has a single task with the owner id set to "testUser". When I create the process I can use the TaskClient.getTasksOwned method to return the created tasks as expected. When I look in the database the tasks are there and have owner and creator set to "testUser".
The second process is called SimpleGroupTaskProcess and has a single Human Task that has groupId = "testGroup". The process is created properly and I am able to examine the database and noticed that the task owner and creator are not set. The potential owner DOES include the "testGroup" so I would expect it to be found. Howevewr it is not retrieved when using the TaskClient.getTasksAssignedAsPotentialOwner passing in the user "testUser" and group "testGroup".
After some digging I think I have found the problem. The key is that the creator and owner is not set on the task. I found the underlying named query called "TasksAssignedAsPotentialOwnerWithGroups" in the orm.xml file. The query was not taking into account the null creator and owner so was only returning the tasks belonging to the "testUser" but not the group assignment.

This appears to work.
I do have a couple of questions though. Should tasks be created in the database without having at least a creator id? Is this expected behaviour for tasks assigned to groups?
I have attached my processes, just in case there is something I've done wrong that someone can help me with.
Thanks

Hi forum,
I have been looking at JBPM5 API and I have a problem connecting to TaskClient from a different server.
So I have my JBPM5.1 server, running.
But from another machine I want to be able to connect to the JBPM5.1 and query the Human Task Service.
Now the problem is that if I query it from localhost or 127.0.0.1, it works fine.
*TaskClient client = new TaskClient(new MinaTaskClientConnector("JBPM Interface", new MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));*
*client.connect("127.0.0.1", 9123);*
But from another machine, running the same code, from another machine, it says that it cannot connect.
*TaskClient client = new TaskClient(new MinaTaskClientConnector("JBPM Interface", new MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));*
*client.connect("10.1.5.13", 9123);*
Now I have tried this on diferent machine and the result is the same.
I have read here in the forum that this is possible, even connect multiple machines to the same Human Task Service.
Do I need to be looking at some configuration? (I have the install.demo config)
Regards,
Nelson
