We don't have anything on-hand for this.
We're free. They aren't. Its as obvious as I could be in this comparison.
I fully appreciate the free vs. cost, however, that is not enough to convince all I must persuade. We have been using JBoss for over 3 years, but not the portal. We have been acquired by a company that uses BEA (we did too, but replaced it with JBoss). I must come up with an apples to apples comparison between JBoss Portal and BEA Weblogic Portal. The absence of a good in depth comparison will swing the decision to BEA, because that is what they are currently using.
So perhaps you may have a list of features you require, and I can answer you if we support them. Feel free to email me personally.
