[jboss-user] [JBoss jBPM] - How to use the Deployed Process Defination
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 WARN [JDBCExceptionReporter] SQL Error: 1, SQLState: 23000

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.
