Thanks, Tom!

I knew there had to be some UML-specific thing that I needed to do to get
the employeeList in the right place.

As for generating the appropriate type, (ArrayLists vs Vectors), my thought
was that I'd simply generate:

List<Employee> employeeList;


And let the user create the right-side of declaration if they want after
the code has been generated.

Is there currently a preference that allows the user to specify what
version of Java they want to use? Perhaps using the Java profile? Since
Oracle doesn't support 1.4 anymore, is there a reason that we would need to
support the non-generic list?

Mark
