Re: Tomcat cannot find subclass
Unlike Tomcat 4, Tomcat 3 uses a delegating ClassLoader. This means that jars in lib/apps can't see classes in WEB-INF/classes. Also, as long as the jar is in lib/apps, Tomcat 3 will load classes from there in preference to the same jar in WEB-INF/lib. "James C.

Above, you have "CountrySelectServlet..." not found, but you say it's actually called "CountryServletSelect..." (Servlet and Select are swapped), so it's right that it not be found. -- Pablo Mayrgundter Director of Applications and Services www.reeltwo.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Tomcat cannot find subclass
Yes, the jar was in WEB-INF/lib, and I took it out in case that was a problem. There was no change in the result when I did. I also suspect a ClassLoader issue. What I would like to know is why? When I subclass a member of a framework, do I have to put my project-unique subclass in the same jar as the common classes? If so, that really sucks. -- Jim McMaster mailto:[EMAIL PROTECTED] In message <[EMAIL PROTECTED]>, "Mike Curwen" said: > Have you tried placing your library in WEB-INF/lib? > There is probably a classloader issue at work. > > > > -Original Message- > > From: James C.

RE: Tomcat cannot find subclass
Have you tried placing your library in WEB-INF/lib? There is probably a classloader issue at work. > -Original Message- > From: James C.
