hi all
i am new to jbpm.
i am trying to implement some web services based on jbpm. i have implemented my services and test it in stand alone mode and it is ok!
but when i am trying to deploy my services on weblogic server it is thrown by some exceptions!
*org.hibernate.HibernateException: Errors in named queries: findTasks, findMessages, findTimers, findGroupsByUserAndGroupType, findProcessInstanceIds, findJo

Truncated. see log file for complete stacktrace*
after searching the internet i have found that adding
*<property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property>*
to hibernate config fix the problem. i have tried the solution and it was successful, but after deploying
when i want to run one of my services it throws another exception
my code snippet is:
*ProcessInstance processInstance = executionService
.startProcessInstanceByKey(processDefinitionId, parameters,
userId + "-" + sequence);*
and the exception is :
*Error invoking com.pardis.notification.core.Services (POJO): org.hibernate.QueryException<ComponentHandler.handleRequest:144>

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="marshaller" isParam="true">org.jboss.jms.wireformat.JMSWireFormat</attribute>+
+ <attribute name="unmarshaller" isParam="true">org.jboss.jms.wireformat.JMSWireFormat</attribute>+
+ <attribute name="dataType" isParam="true">jms</attribute>+
+ <attribute name="socket.check_connection" isParam="true">true</attribute> +
+ <attribute name="serverBindAddress">${jboss.bind.address}</attribute>+
+ <attribute name="serverBindPort">4457</attribute>+
+ <attribute name="clientSocketClass" isParam="true">org.jboss.jms.client.remoting.ClientSocketWrapper</attribute>+
+ <attribute name="serverSocketClass">org.jboss.jms.server.remoting.ServerSocketWrapper</attribute>+
+ <attribute name="numberOfCallRetries" isParam="true">5</attribute>+
+ <attribute name="pingFrequency" isParam="true">5000</attribute>+
+ <attribute name="pingWindowFactor" isParam="true">2</attribute>+
+ <attribute name="onewayThreadPool">org.jboss.jms.server.remoting.DirectThreadPool</attribute> +
+ <attribute name="stopLeaseOnFailure" isParam="true">true</attribute>+
+ <attribute name="clientLeasePeriod" isParam="true">10000</attribute>+
+ <attribute name="validatorPingPeriod" isParam="true">10000</attribute>+
+ <attribute name="validatorPingTimeout" isParam="true">5000</attribute>+
+ <attribute name="failureDisconnectTimeout" isParam="true">0</attribute>+
+ <attribute name="callbackErrorsAllowed">1</attribute>+
+ <attribute name="registerCallbackListener">false</attribute>+
+ <attribute name="useClientConnectionIdentity" isParam="true">true</attribute>+
+ <attribute name="timeout" isParam="true">1800000</attribute>+
+ <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.

"Process deployment in jBPM 5"

--------------------------------------------------------------
Hi
I am new to jBPM. I have downloaded jBPM5 and installed it as per the procedure given in the Read me file that came with the installaton zip.
Basically, I extracted the zip file and ran the ant start.demo command. The installation completed without any issues and the services did start.
I was able to view the Evalucation process from that came as a part of the demo using Eclipse. Started the process using ProcessTest.java. Was also able to start it and complete the tasks using the jbpm-console.
A few questions -
1) I want to create a new bpmn process and deploy that using Eclipse. I have created the process but am not sure of the deployment procedure. What is the procedure to be followed?
2) How do I add new users and groups to the system?
3) I am not able to open the reports, the attached error is thrown in the jbpm-console. How to I start the report server?
Is there are documentation for beginners?

--------------------------------------------------------------
Is there a settign that woudl let my war deploymnets use the invoker servlet. In JBoss5 I was able to use it by editing the context.xml file and addin a mapping in the web.xml of the war. My web.xml looks somehting like this:
<servlet>
<servlet-name>ZZRead XML</servlet-name>
<servlet-class>azzreadxml</servlet-class>
</servlet>
<servlet>
<servlet-name>invoker</servlet-name>
<servlet-class>
org.apache.catalina.servlets.InvokerServlet
</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
</web-app>
When I deploy the war file, I get the following error:
EPLOYMENTS IN ERROR:
Deployment "vfs:///usr/local/jboss-6.0.0.Final/server/default/deploy/obsolete.war" is in error due to the following reason(s): java.lang.ClassNotFoundException: org.apache.catalina.servlets.InvokerServlet from BaseClassLoader@5c393d95{vfs:///usr/local/jboss-6.0.0.Final/server/default/deploy/obsolete.war}
