Best practices for class loading issues [message #65664]

Hi!

I'm wondering how do you guys solve issues raised through class loading
issues by some typical Java Enterprise components (for example, EJB3).

Do you use buddy class loading?
Do you use fragments?
Do you use a combination of the above?

What is the "best practice" for such issues? AFAIK all such frameworks
are written without taking class loader hierarchies in mind.

Of course, the optimal solution would be to create support for the
extension registry and/or declarative services. But that would take
quite some effort. ;)

Cu, Gunnar

Hey Gunnar,

Can you be more specific about the problems encountered? they are all
different and may require different solutions.

I don't have any problems so far but I wonder if there will be some when
the dependency tree grows. ;)
