Yeah, well look at what we get from IBM.  The primary reason many of
WebSphere's components are so poor is that the use a lot of EJB
processing.

I've never said Java is a bad language.  I am a Java evangelist and use
it every day.  I just don't find it productive for business rules, for
the reasons I've stated (data conversion, bad decimal processing).

There are places where Java shines, and I use both Java and RPG as
appropriate.  But until you can write an MRP explosion in Java that
rivals the performance of an RPG version, then Java is the wrong choice
for complex business logic.
