problem closing services - Caused by: org.jbpm.persistence.J

[bbela]

Hi!

I have a problem with persistence too.

JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
//... process management statements ...
jbpmContext.close();

At the .close() call I get the following Exception:

org.jbpm.JbpmException: problem closing services {persistence=org.jbpm.persistence.JbpmPersistenceException: couldn't commit hibernate session}

Hlp Plz!
Thx!

I am not really sure, but this looks like you have attached objects to the object graph outside of a hibernate session. What exactly are you trying to do in your 'process management statements...'. Can post them here?

HI... did u already resolve this problem=? because i am having the same problem...

here's.. my code:

static {

jbpmConfiguration = JbpmConfiguration.parseXmlString(

public void inst (int i)
{

//int version;
JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
try {

GraphSession graphSession = jbpmContext.getGraphSession();

ProcessDefinition processDefinition =
graphSession.findLatestProcessDefinition("teste");

// With the processDefinition that we retrieved from the database, we
// can create an execution of the process definition just like in the
// hello world example (which was without persistence).
ProcessInstance processInstance =
new ProcessInstance(processDefinition);

//version=processInstance.getVersion();

// processInstance.signal();
//processInstance.signal();


Token token = processInstance.getRootToken();

// Also after construction, the main path of execution is positioned
// in the start-state of the process definition.
// assertSame(processDefinition.getStartState(), token.getNode());

// Let's start the process execution, leaving the start-state
// over its default transition.
token.signal();


// Token token = processInstance.getRootToken();
// assertEquals("inicio", token.getNode().getName());
// Let's start the process execution
// token.signal();
// Now the process is in the state 's'.
// assertEquals("inicio", token.getNode().getName());

// Now the processInstance is saved in the database. So the
// current state of the execution of the process is stored in the
// database.
jbpmContext.save(processInstance);



} finally {
// Tear down the pojo persistence context.
jbpmContext.close();


}
//return version;
}
}


Can anyone see?

iam also gettign the excetion that u ppl got her is the code that iam using to close(end()) the task instance.
ProcessDefinition processDefinition = graphSession.loadProcessDefinition(processDefinitionId);
ProcessInstance processInstance = jbpmContext.newProcessInstance(processDefinition.getName());
ContextInstance contextInstance = (ContextInstance) processInstance.getInstance(ContextInstance.class);
TaskInstance startTaskInstance = processInstance.getTaskMgmtInstance().createStartTaskInstance();
startTaskInstance.end();
if any one got the solution please let me know.

I have the similar problems. When I deployed using jbpm starter kit. It works OK. But in Geronimo, the hibernate connection lost after several hours.
