[jboss-user] [JBoss jBPM] - Error when calling a process from a java class

[ssidhanta]

Hi,

I am calling a JBPM process from a java class using the following code:

    JbpmConfiguration jbpmConfiguration = JbpmConfiguration.parseResource("jbpm.cfg.xml");  
    //ProcessDefinition processDefinition=ProcessDefinition.parseParResource("D:\jbpm/src/process.examples/simple.par/processdefinition.xml");  
    ProcessDefinition processDefinition=ProcessDefinition.parseParResource("simple.war/processdefinition.xml");
    JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
    ProcessInstance processInstance=new ProcessInstance();
    jbpmContext.deployProcessDefinition(processDefinition);
    Token token=processInstance.getRootToken();
    assertSame(processDefinition.getStartState(), token.getNode());
    token.signal();
    assertSame(processDefinition.getNode("first"), token.getNode());
    token.signal();
    assertSame(processDefinition.getNode("end"), token.getNode());

On deploying the WR file I am getting this error in the above java class.

description The server encountered an internal error () that prevented it from fulfilling this request.
