Images are ok. I did some proof reading. I repaired some formulations.

The biggest concern I have is about naming that server. It think it is not "the JBoss Unified ..." but just "JBoss Unified" without that "the" article.

It is the same thing as you do not say "the Microsoft Windows", you name it directly. It does not have much sense to use it with article.
