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 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4067216#...
