[jboss-user] [JBoss jBPM] - Concurrent Processing in JBPM

[meet_nagi]

I am new to JBPM and have a question on concurrent processing handled by JBPM.
Below is the block of code showing my usage of JBPM

// Get the JBPMContext
jbpmContext = getJBPMContext();
// Get the process instance for the process instance id passed.

ProcessInstance processInstance = jbpmContext.loadProcessInstance(processInstanceId);
Token token = processInstance.getRootToken();
token.signal();
jbpmContext.save(token);
jbpmContext.save(processInstance);

My question is before transaction A issues an explicit save another transaction B modifies the same records then how JBPM will handle transaction A?

I hope I will get answre to my question.

Thanks
