HelloWorld3 should now be working. Cool! Thanks to Denny and Jake in finding and fixing this...

Now, these jars ARE installed in Tomcat's shared/lib. So, I moved these to Tomcat's endorsed directory, and voila! everything works again! Ok, very cool...I will upgrade accordingly on the server and check it out up there as well. We probably need to come up with a nice, clean install doc that explains exactly what to put where...I'll try and do that this weekend. Thanks for your help on this!

Well, as it turns out, this seems true in every case except the one dealing with the XMLC templates compiled from XML files rather than HTML files. The fix is quite simple. Remove xercesImpl.jar and xmlParserAPIs.jar from CATALINA_HOME/common/endorsed. It will work perfectly, I promise. Or, you can always use the JDK1.4-lite version of Tomcat. However, that excludes more libs than just the xml parser and I'd suggest using the full version and deleting the jars as stated previously. Now, I know that this was a problem even with XMLC compiled HTML files at one point before Richard Kunze made some modifcations to allow xerces to be in shared/lib even when Xerces2 was in common/endorsed. I just can't remember what those mods were? Richard, if you are reading this, could you expound on what you did to make the latter case work? Can the same be done for the case of XMLC compiled XML templates? Hopefully you remember the change you made (and the conversation we had about it). The other stuff about not putting xerces and xalan (or any of the xmlc classes, IMO) in WEB-INF/lib is still completely valid and has little to do with this issue. The should be in shared/lib and nowhere else.

Its possible that this was introduced in the last version of XMLC and just not caught until now...Jake - you've spent some time looking at the internals of XMLC; any thoughts here? I'll look at htis more later once I get a bit of time...
