[jBPM Users] - Re: StaleObjectException in JBPM 4.0
by mmusaji
Apologies Ronald, I was hoping for more of a discussion as opposed to a solution to my specific problem.
Here's the fork and join from my workflow.
| <java class="org.workflow.FindProviders" g="276,7,80,40" method="execute" name="find providers">
| <transition name="" to="fork"/>
| </java>
|
| <fork g="298,85,80,40" name="fork">
| <transition g="-62,-18" name="validate red" to="validate red request"/>
| <transition g="-64,-18" name="validate exp" to="validate exp request"/>
| <transition g="-63,-17" name="validate sys" to="validate sys request"/>
| </fork>
|
| <custom continue="async" name="validate red request" class="org.workflow.Validate1" exp="#{myFirstObj}">
| <transition g="-27,-18" name="" to="join"/>
| </custom>
|
| <custom continue="async" name="validate exp request" class="org.workflow.Validate2" exp="#{mySecondObj}">
| <transition g="-27,-18" name="" to="join"/>
| </custom>
|
| <custom continue="async" name="validate sys request" class="org.workflow.Validate3" exp="#{myThirdObj}">
| <transition g="-27,-18" name="" to="join"/>
| </custom>
|
| <join g="267,368,80,40" name="join">
| <transition name="check results" to="evaluate validation results" g="-47,-16"/>
| </join>
| ...

Starting the process using JobExecutor config
<jbpm-configuration>
|
| <process-engine-context>
|
| <job-executor threads="5" idle="10" idle-max="0" lock-millis="0" />
|
| </process-engine-context>
|
| </jbpm-configuration>
Using MySQL and everytime I run the forks run concurrently as expected. But then sometimes in between the forks or sometimes after I get this exception

I read somewhere this is expected behaviour but this surely can't be right... can it?

[Beginner's Corner] - wlfullclinet.jar with jboss
by suneel_nani
Hi
I am new to jboss
I am trying to put wlfullclinet.jar in the classpath of getting the following error
17:07:00,550 ERROR [AbstractKernelController] Error installing to Create: name=jboss.jacc:id="vfsfile:/usr/apps/tools/build-server/jboss-5.0.1.GA-jdk6/temp/jboss-5.0.1.GA/server/default/deploy/management/console-mgr.sar/web-console.war/",parent="console-mgr.sar",service=jacc state=Configured mode=Manual requiredState=Create
java.lang.RuntimeException: java.lang.ClassNotFoundException: JACC:Error PolicyConfigurationFactory : cannot find class : null
at org.jboss.deployment.security.JaccPolicy.create(JaccPolicy.java:87)
What is the best way to put weblogic specific jar file(wlfullclinet.jar) so that i can invoke EJB or JMS or Webservices from Jboss
Thanks
Sunil Polineni
