[seam-dev] Subtle changes in seam-gen affecting JBDS :)

[Dan Allen]

Sigh. I have explained this before, but I take the blame for not making this
information part of the official documentation. Perhaps I should.

Here's the story. The purpose of the tokenized file is to allow the same
build to target different application servers. Right now, JBoss AS 5 and
GlassFish are supported. This cannot be done at project setup time because
the point of supporting multiple servers is to demonstrate portability of an
application, hence a switch at build time.

Before raising objection to token replacements, know that I have set it up
so that the JBoss Tools sees files in the place it expects to see them with
explicit values. The tokenized files are only used by Ant when running the
build for GlassFish or with an alternative profile (in theory).

With that said, there could be bugs in this setup. The problem is that
people keep changing the files without a full understand of how everything
works. I know, it is confusing as hell. We have established already that
seam-gen is just not going to get any better until it is rethought. It was
never designed to support JBoss Tools. Therefore, we have these problems.

We really need to just leave seam-gen as it is at this point because the
complexity is too high for it to be stable with so many hands in the pot. I
know Pete said that a year ago, but we really need to support GlassFish to
fix the perception that Seam only worked on JBoss AS. Yes, it was risky, but
it has expanded our user base, so it was worth the effort.
