Hi,
I am new to JBPM. I am using JBPM 3.2.3. I am getting the following exception while
creating a new process instance. I have deployed the process definition only for the first
time as it is putting an entry everytime in JBPM_PROCESSDEFINITION table.

Here is the code i am using to get Jbpm context, Jbpmconfiguration, ProcessDefinition:
JbpmConfiguration configuration =
JbpmConfiguration.parseResource("jbpm.cfg.xml");
//configuration.createSchema();
JbpmContext context = configuration.getCurrentJbpmContext();
if(context == null) {
context = configuration.createJbpmContext();
}
ProcessDefinition definition = null;
GraphSession session = context.getGraphSession();
definition = session.loadProcessDefinition(1);
System.out.println(" Process Definition reference in JBPM Server :: " +
definition);
if(definition == null) {
definition =
ProcessDefinition.parseXmlResource("processdefinition.xml");
context.deployProcessDefinition(definition);
}
Here is the code i am using to create a new process instance:
// Code to get process definition goes here
// Creating a process instance
ProcessInstance instance = new ProcessInstance(definition);
I am able to see the process definition reference in my logs. But not able to understand
why the exception has occured and process instance is not created?
Anyone please help me on this as it is very urgent
Thanks in advance.
Regards,
Sakthi
