ClassNotFound exceptions with Tomcat/4.0-b2

[S Ramakrishnan <rk...@cisco.com>]

Environment:
   Windows2000
   Tomcat4.0-b2 standalone

Problem:
I recently upgraded to Tomcat/4.0-b2 from the previous version of
4.0. I find that its not able to locate the servlet class files
under webapps/<mywebapp>/web-inf/classes.
I do not have a security manager installed.

This used to work before I upgraded. Is there a quirk with
TC4.0-b2 about loading classes that I should be aware of?
Also, what should be approach to troubleshoot this failure
to load this class? I have set debug to 4 and am tracking
logs\localhost_log*txt.

The context is defined as follows:

  <servlet>
    <servlet-name>
        Quote
    </servlet-name>

    <servlet-class>
        Quote
    </servlet-class>
  </servlet>


Any hints appreciated,

Thanks,

If the actual directory name is "web-inf", then that is your problem.  All
pathnames in Tomcat 4.0 are case sensitive, so this must really be
webapps/<mywebapp>/WEB-INF/classes instead.

Is "Quote.class" in the WEB-INF/classes directory?  Along with any other
classes that it depends on?
