As much as I kow every thing you put in the jre/lib/ext becomes 'part of the jre' and will be treated as an extension to the jre.

Dezember 2002 00:53 To: Cactus Users List Subject: [Resolved] Baffled by classpath problem Ok, after nearly a day's worth of mostly banging my head on my desk, I finally got my Cactus installation working! The culprit was a copy of cactus-1.4.1.jar in my $JDK_HOME/jre/lib/ext folder. I think I'd put that there originally beause the Classpath Howto indicates that cactus.jar is one of the things that needs to be in the client-side classpath. However, by putting it in the extensions folder I'm guessing that I also made it part of the server's classpath (since I'm working and running tomcat on the same machine), which messed things up. Why on earth that produced a "java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet", I don't understand at all. That should probably be in a FAQ -- or am I the only one who makes mistakes like this? Anyway, thanks to those who responded for your help. Time to start writing test cases....
