3:51 a.m.
i am trying to implement jBPM in a J2EE Web application. I am doing three things.
1) Deploy a process
2) Start an instance.
3) Show a list of available instances.
My Environment:
jBPM : 3.2.X
jBoss : 4.2.X
Database: MySQL
Below is the piece of code embedded in a method inside a DAO class. This is invoked from
the servlet when the user hits the Deploy button in the jsp page.
| public String redeployProcess(String processName) {
| System.out.println("->public String redeployProcess(String
processName)");
| System.out.println("----->Creating jBPM Configuration....");
| JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
| try {
| System.out.println("----->Parsing process definition....");
| ProcessDefinition processDefinition =
ProcessDefinition.parseXmlResource(processName);
| System.out.println("----->Deploying Process definition....");
| jbpmContext.deployProcessDefinition(processDefinition);
| System.out.println("----->Deploy Successful....");
| return "Process " + processDefinition.getName() + "
redeployed.";
| } finally {
| System.out.println("----->Closing jBPM Context....");
| jbpmContext.close();
| }
| }
|
And this is the exception i got....
| ->public String redeployProcess(String processName)
| 13:45:38,882 INFO [STDOUT] ----->Creating jBPM Configuration....
| 13:45:38,882 INFO [STDOUT] ----->Parsing process definition....

Works well in Tomcat !
I ran this application in Tomcat and it worked perfectly alright. Initially i faced some
problems but with the help of existing posts, i made it work well.....
Why not in jBoss ?
If it works well in Tomcat, then it must work in jBoss too. And also i dont know
Hibernate. I can see that it is trying to get a Session through
SessionFactoryImpl.getCurrentSession() and the effort fails.
But how is it able to get one in Tomcat ?
Any help here would be deeply appreciated. if I am missing out to provide any info, please
do ask me.
