I've used Tomcat and Weblogic, and can offer a brief comparison: 1/ Co$t. You can't beat Tomcat's price. WL licensing is based on the number of CPUs in the machine. (Doesn't sound too bad until you have 40+ CPUs involved. ;) 2/ Spec compliance/upkeep: Tomcat 5.x implements servlet spec 2.4, while (IIRC) Weblogic 8.1 is still 2.3. Granted, BEA has several reasons to take the Corporate "slow and steady" Pace; but it's nice that I can use the servlet 2.4/JSP 2.0 features *now* instead of waiting. 3/ Clustering: Weblogic wins here, not so much because WL clustering is any "better" but because it's been tried and tested. I've been using WL clusters for more than 4 years now, since v5.1. By comparison, Tomcat clustering appeared in v5.0 (last year, was it?) so it hasn't experienced nearly as much road-testing. 4/ Webserver connectivity: I've never had a problem with mod_jk; but based on list posts, I'm the pathological case. (The ratio of jk flaws vs pilot error is beyond me.) Setting up the Weblogic Proxy Plugin was a complete no-brainer, vs mod_jk which was a partial no_brainer. 5/ All-In-One package: What are your long-term app dev goals? WL provides EJB and other features out of the box. As others have mentioned, doing that with Tomcat involves adding other products to the mix, which can slow down a pre-product R&D effort. 6/ Hand-holding: for a fee, BEA can send a pro-serv team to your site and/or provide training. There is no "official" (Apache-based) Tomcat consulting/pro-serv, as far as I know. While unofficial services are certainly available, you'd have to shop around, check credentials, etc. That said, don't let the "open source" vs "vended" labels fool you. The support models aren't too different as long as you don't deviate too far from the norm with your app/setup, and you're conservative about upgrades. What you really have to worry about is "in it for the long run" vs "fly-by-night"; and neither Tomcat nor Weblogic show any signs of disappearing for the forseeable future. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
