Hi everybody!
I have one entity Process
with a OneToMany relation with another entity KillerQuestion
as follows:
@OneToMany(cascade = CascadeType.ALL, mappedBy = "processId")
private List<KillerQuestion> killerQuestionCollection;
In one SFSB I oftenly refresh the process calling the following method:
private void refreshProcess(){
try{
em.refresh(process);
} catch (EntityNotFoundException exc){
System.out.println("EntityNotFoundException");
}
}
If I open 2 different windows in my explorer and:
1. Delete one KillerQuestion entity in one window
2. Refresh the process
in the other window using the method showed above
I get an EntityNotFoundException.
I would like that if I refresh the process
entity in the second window, the process
would be refreshed correctly.
I have tryed to get again from the EM the process
entity as follows:
private void refreshProcess(){
try{
em.refresh(process);
} catch (EntityNotFoundException exc){
System.out.println("EntityNotFoundException");
em.find(Process.class,processId);
}
}
but I got an exception because the transaction is no longer active:
16:06:40,802 ERROR [JDBCExceptionReporter] Transaction is not active: tx=Transac
tionImple < ac, BasicAction: -588b52d0:623:47fe0ca2:b95 status: ActionStatus.ABO
RT_ONLY >; - nested throwable: (javax.resource.ResourceException: Transaction is
not active: tx=TransactionImple < ac, BasicAction: -588b52d0:623:47fe0ca2:b95 s
tatus: ActionStatus.ABORT_ONLY >)
16:06:40,802 INFO [DefaultLoadEventListener] Error performing load command
org.hibernate.exception.GenericJDBCException: Cannot open connection
Concerning this issue I have the following questions:
1. Is there a way to avoid the EntityNotFoundException and that the process is refreshed properly?
2. Is there a way to reactivate
the transaction so that I can execute the em.find method after the EntityNotFoundException?
Thanks for your help.
Cheers
