does this mean that by the time the bean gets loaded, the utility classes
will already have been loaded? (this would be good).

As far as I know the utility classes were being put in the jar for 2

    1) If all classes needed to run the EJB are in the jar, then these
classes will be loaded by the class loader when the bean is first loaded.
This can be good for performance

    2) keeping all the classes in the jar cuts makes sure the EJB will run
as is - it does not rely on the class path to be set correctly (something
that the bean itself has no control over).

Can you give me any pointers on how to use the <support> element?
