Guys, not to be short-tempered here or anything, but open your eyes!

These class loading issues have been a hot topic on the list for the last week, while all

1) Search or browse the list the archives.

2) See classloader.html that describes Catalina's class loading architecture.  You might have
to browse the CVS repository... /jakarta-tomcat-4.0/catalina/docs/dev/classloader.html.
