I've run into the problem of the JSP 2.0- Examples not rendering in the last two installs I've done of Tomcat.
On the last install I resolved the problem by: --removing all of the JDKs and JREs through Windows Settings > Remove Programs, --removing any j2sdk folders -- reinstalling the jdk which created a j2sdk1.4.2_05 folder. --pointing the environmental variable JAVA_HOME to the j2sdk1.4.2_05 folder After doing all that the JSP 2.0 examples worked. I'm not sure why the extra JRE and JDK installations were running interference....I'd think that if JAVA_HOME was pointing to the j2sdk1.4.2_05 any other jars that are lying around wouldn't matter..... maybe my environment CLASSPATH variable was pointing to a different JRE and that overode the JAVA_HOME setting? I dunno....but starting from a clean install definitely seemed to help. Although I like Java and find it challenging to program in, I find the installation of a Java development environment sometimes unfuriatingly difficult with all the classpath gotchas. There really should be a way of designing a less fragile installation that isnt as contingent on everything else being just so. Introductory texts on Java programming like to talk up all the benefits of encapsulation and I guess they've been incorporated into the language. But when it comes to a Tomcat install it seems that encapsulation wasn't given much attention * at least if encapusalation means insulation from outside environments. Is this a sensible impression or maybe I'm misunderstanding something?

There is only one each of the two jasper jars, and no jsp.jar or jsp-api.jar in the installation directory (or in the download zip file jakarta-tomcat-4.1.31.zip) Are those two jars supposed to be included?? The only place I even find the jsp jars is in the Eclipse and MyEclipse toolkits. Eclipse is an IDE, and I'm bringing up tomcat (at least initially) outside of the IDE. Are these two jsp jars something I should have and so I should go get them seperately from the tomcat distro? And where should they go?
