Yes, members of the WebMacro mailing list have been far more
supportive. Go figure.

I wonder the justification here myself.

In my opinoin, a graphics artist shouldn't be expected to write this.

In the servlet you say:
context.put("isps", isps);
This makes a $isps variable available in the WebMacro template's
context. It's similar to how RequestDispatcher works by passing in
attributes in the request. Add as many variables as you want.
List-ish objects (arrays, Enums, Vectors, etc) can be automatically
iterated over. Beans can have their props automatically read.

I have a long list of hilarious error messages that you'll never be
able to figure out without the source.

Most ISPs don't give you 13 Gigs to play with. They give you 30 Megs.

Most don't.

Thanks. Raising awareness is my goal.
