hello everybody,
i am implementing Drools in our project(using Spring3.0 + JPA2.0), initially
i was working with Drools 5.1.M1 and now newely started with M2,
the problem is i dont understand how M2 tracsactions work
what i have done is i used the spring based jpaSessionServiceFactory for
transactions in my project and created the following methods
@Transactional
public void startProcess(String processName,Map<String,WorkItemHandler>
handlers,Map<String,Object> parameters)
@Transactional
public void resumeProcess(long workItemId,Map<String, Object>
results,Map<String,WorkItemHandler> handlers)
As you can see both methods i made them as transactional
i have one more Service DAOService which deals with DB(CRUD operations)
now i have simple flow as Start --> Action --> End
in the Action node i call one of the CRUD method (as DAOService is made
Global ) what i observed is the method fails giving exception(given at the
end of this message)
this exception occurs only in delete case of CRUD
know why this happens..................
Exception :
java.lang.RuntimeException: unable to execute Action
