I'm trying to install tomcat and I found some installation instructions for tomcat 5.5. I'm going to be using tomcat for local development of servlets and jsp. What version of tomcat should I install? I'm leaning towards 5.5, so that the install won't cause any unforeseen problems plus I'm using the book "Head First Servelts & JSP", which uses the same servlet/jsp spec as 5.5. But the current version of tomcat is 6.x. Should I go with the current version?
