[jboss-user] [EJB 3.0] - Building reuseable components

[martin ganserer]

Hi,

in several projects we have implemented yet we found out that there are some aspects that we use again and again.
For example we have defined a SLSB that provides other modules with auto generated IDs in a predefined format. 
The SLSB works with one conifguration entity in the background.
What I would really like is to define a separate jar or ear that can be linked to all projects that need specific ID generation.
I think that one problem is to work with multiple persistence units.
What are further traps? Or is it maybe better to keep the hands off such an implementation?

What do the experts think about?
