So you have to make sure that parallel servlet threads don't 
access the
broker variable without proper synchronization.


How could I be sure?
I answered this in my original reply: always allocate new broker 
instances and release them back to the pool after use.

How do you mean about proper synchronization?
I meant using Java synchronization to lock access to the broker instance.


Do you say that all threads use the same class instance?
If you mean Class object then yes,
If you mean instance of a class then no.


I don't understand what you mean? What's the difference between a Class object and an instance of a Class?
java.lang.Object.class is an object of type java.lang.Class

new Object() is an instance of the class java.lang.Object().




If I declare each time a new PB instance, is this solution 
thread safe?
You have to make sure that each thread (also servlet engine 
threads) always
work with their only broker instance and not with a shared instance.
The most simple way to achieve this is to use a new PB 
instance in each
call.


OK. You declare eache time a new PB instance like:
PersistenceBroker pb = PersistenceBrokerFactory
exactly!

Thanks
Sylvain

Of course it's important to close the PB imediately after the 
unit of work
is completed

cheers,
Thomas

Thanks
Sylvain

  broker = 
PersistenceBrokerFactory.defaultPersistenceBroker();

recommened to use
PersistenceBroker pb = PersistenceBrokerFactory
in your methods

  broker.beginTransaction();
  Iterator iter = broker.getIteratorByQuery(query);

  while (iter.hasNext()) {
Person person = (Person) iter.next();
appResps.put(person.getPersonId(), 
person.getPersonName());

  } 
  
  broker.commitTransaction();
} catch (PersistenceBrokerException t) {
broker.abortTransaction();
t.printStackTrace();
} finally {
broker.close();
}

hmm, I'm not familiar with webserver internals, but think if
you press 'stop' on the browser your method will be pass
through anyway.
StackTrace of the exception on refresh?
Caused by 'broker.abortTransaction()'?
If yes, I think it's a thread problem.


How could I test it?

If the exception really caused by
broker.abort in searchPerson(String lastName),
don't use the class field broker in your search method

Maybe the PB instance isn't closed when I stop the

How could I close the PB intansce when I stop the browser?
How could I manage this?
Is someone has an experience?
Can you describe more detailed, some pseudo code?

The servlet engine uses parallel WorkerThreads to handle all incoming
requests.

If you mean Class object then yes,

Just some question to be sure to understand:

How could you define a thread in this case?
Do you say that all threads use the same class instance?

If I declare each time a new PB instance, is this solution thread safe?

Hello,

I'using PB intances to retrieve info from my database.
When the time to search information is too long you can 
press the "stop" button on the browser.

But when I restart my application there is a 
TransactionNotInProgress exception.

Maybe the PB instance isn't closed when I stop the transaction!??
How could I close the PB intansce when I stop the browser?
How could I manage this?
Is someone has an experience?
Can you describe more detailed, some pseudo code?
Which version do you use?
regards,
Armin

Thanks
Sylvain

RE: PB error when the browser is stoped

[Sylvain.Thevoz]

Hello Armin,

I'm using OJB 0.9.5.

The code is below.

The "stop" button is pressed during the execution time of this method below.
I think that there something wrong because after I press "stop" and refresh the page, 
a TransactionNotInProgressException occured.

Have you an idea?
Thanks
Sylvain


**code**
public void searchPerson(String lastName) {
  Criteria crit = new Criteria();
  crit.addLike("lastName", "%" + lastName + "%");
  Query query = new QueryByCriteria(Person.class, crit);
  
  try {
broker = PersistenceBrokerFactory.defaultPersistenceBroker();
broker.beginTransaction();
Iterator iter = broker.getIteratorByQuery(query);

while (iter.hasNext()) {
  Person person = (Person) iter.next();
  appResps.put(person.getPersonId(), person.getPersonName());
} 

broker.commitTransaction();
  } catch (PersistenceBrokerException t) {
  broker.abortTransaction();
  t.printStackTrace();
  } finally {
  broker.close();
  }

}
**code**
