Multiple instances of a Seam component

[priyasrihari]

In my Seam - JPA(Hibernate) project, I have a Quartz scheduler that executes a database query based on a cron trigger and to perform additional processing on each record from the query , I use a ThreadPoolExecutor which assigns a thread per record.  In doing so, I would expect that each thread operates on  different instances of a Seam component. Instead its the same instance that is used each time and this results in a lot of hibernate-entity manager specific exceptions - Session is closed, EntityManager is closed, and a horde of other hibernate-specific exceptions.
Also in this case, I cannot use @Roles for the component in question since the number of instances required is dynamic as the number of threads simultaneously executing active tasks.

Can you suggest how i can get multiple instances of a component in Seam dynamically.

Thanks in advance.

Hello, we had this issue recently and we solved it this way:

@Name("dynamicComponent")
class DynamicComponent implements Runnable {
  public void run() {
    // do things...
  }
}

@Name("dynamicController")
class DynamicController {
  void doStuff() {
    for (int i = 0 ; i < 5; i++) {
      new Thread(Component.forName("dynamicComponent").newInstance()).start();
    }
  }
}

We printed the references of the objects and they all are different.
