That's because they have to put their hooks and claws into the tomcat code before releasing it. But they are only one or two minor revisions behind. The latest that I'm using is 5.0.19.
You may be able to find tomcat5 on your jboss right now - there's an
ant script to run that will create the jbossweb-tomcat50.sar directory for you. I'm not sure if it is with every release. I am using a build of the CVS tree because there was a bug fix in it I needed. Try downloading jboss 3.2.4RC1
I have seen things you people would not believe, attack ships on fire off the shoulder of Orion, c-beams sparkling in the dark near the Tennhauser Gate. All these moments will be lost in time, like tears in the rain.
