Thank you Uli. I had already taken a look at the two pointers you have provided, without really understanding them: I'm a bit lost on how to start with. I've understood that I must create a service and declare it inside the AppModule class. I've seen that I should declare an interface for such a service, and of course an implementation. I've seen that the "PerthreadManager" instance seems to be injected into the service implementation.
But: - I do not understand the exact purpose of this "PerthreadManager" class (since we only use its "cleanup()" method) - I do not know how to declare the service in the IoC (is that like any regular service in the "bind()" method ?) I must also indicate that each client servlet will create its own notification thread, and I am afraid that a central service will not help... Thank you for your help.
