(well orion may have it's own >JSP container? JBoss 2.4 (which is the one I use currently) uses Tomcat to >run 8). Orion does have a JSP container, and it's pretty good. Incidentally, I'd suggest using Jetty to run JSP in JBoss; if you're using JBoss 3.0, though, the version of Jetty that get shipped is incorrect (relying on yet another broken version of Tomcat's jasper.) Update to the current stable Jetty will fix the problem. This is really where JBoss shines; because it's VERY component-driven, if you find that you dislike one product (say, the servlet container) and need to swap it out... do so! You can do that with other products as well (WebLogic, Orion, WebSphere, etc.) but JBoss puts the "wap" in "swap." (Ob. WebSphere derogatory comment: "WebSphere put the 'ick' in 'slick.'") (Same for WebLogic: "WebLogic put the 'ow' in 'slow.' For the lawyer types: no, this is not a benchmark! Please don't sue!") (Same for Orion: "Orion put the... say, where ARE those docs?") (And lastly, for JBoss: "JBoss put the... well, I know it put the thing SOMEWHERE. After I pay for the docs, I'm sure I'll know.") I'd include more, but sheesh, it's 5:15 a.m., I'm tired. :) >scot. > > > -----Original Message----- > > From: Jason Bell [mailto:[EMAIL PROTECTED]] > > Sent: Monday, 23 September 2002 18:30 > > To: JDJList > > Subject: [jdjlist] Re: J2EE, Tomcat, JBoss, etc. > > > > > > Tim > > > > Okay, I'm gonna say this once and only once.
