[jboss-user] [JBoss jBPM] - How to use the Deployed Process Defination

[prabhu_rdm]

Hi Folks,

I have some issue on using the deployed process definition. Check out the following code

try
{
GraphSession graphSession = jbpmContext.getGraphSession();	    
	    
ProcessDefinition processDefinations =                                                                                    graphSession.findLatestProcessDefinition("ApprovalProcess");

if(processDefinations == null)
	    	jbpmContext.deployProcessDefinition(processDefinition);		
			 
processDefinition =  graphSession.findLatestProcessDefinition("ApprovalProcess");		
		
ProcessInstance processInstance = new ProcessInstance(processDefinition);  
		
	
Token token = processInstance.getRootToken();
token.signal();
 }
finally{    	jbpmContext.close();	    }

Here I check whether process definition is already deployed or not? If not I deploy it orelse I take the existing process definition

But when I run this code I get the following constraint error

10:59:53,546 INFO  [STDOUT] Hibernate: insert into JBPM_PROCESSINSTANCE (VERSION_, KEY_, START_, END
_, ISSUSPENDED_, PROCESSDEFINITION_, ROOTTOKEN_, SUPERPROCESSTOKEN_, ID_) values (?, ?, ?, ?, ?, ?,

10:59:53,687 ERROR [JDBCExceptionReporter] ORA-00001: unique constraint (FINDEVNEWCOA.SYS_C0061240)
violated

I think this is because of the process defination column  in the process instance table is defined as unique key.

If I deploy the process defination everytime to create a process instance, then it works fine.

whether we need to deploy the process definition every time to create a process Instance?

how to use the existing process defination to create a process instance?

Folks, need suggestion from you.

Thanks in advance,

Prabhu.
