The Matrix (for App Servers)
TSS has volunteered to host the appserver matrix. This is a nice matrix that I've used in the past while teaching.
TheServerSide is pleased to announce that we will now be hosting the J2EE Application Server Matrix which was formerly available on Flashline.com. The 'Matrix' is a detailed listing of J2EE vendors and their application server products, with information on latest product version numbers, J2EE spec support and licensing, pricing, platform support, and links to product downloads and reviews.
