I have been trying to solve the following error. I also looked up for solutions in the groups and a in couple other websites but nothing seems to solve the problem. The following is the problem description:

 I have unzipped & installed tomcat-4.1.30 on Sun Solaris (Unix). I run tomcat on port 8118 and it works fine. I also executed a couple of examples from <...>/examples/jsp and they work fine too. Then I created 2 new folders under webapps as follows
<...>/webapps/users/pkhann1
(here users & pkhann1 are the new folders that I created)
Then I copied the dates folder from <...>/webapps/examples/jsp/dates to <...>/webapps/users/pkhann1/ and then I created another folder WEB-INF/classes as follows
<...>/webapps/users/pkhann1/WEB-INF/classes
and copied the respective class & java file of dates as follows:
<...>/webapps/users/pkhann1/WEB-INF/classes/JspCalendar.class
<...>/webapps/users/pkhann1/WEB-INF/classes/JspCalendar.java

But when I try executing dates.jsp, i get the following error:
HTTP Status 500 -
type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

root cause
java.lang.ClassNotFoundException: dates.JspCalendar

I have tried to do the following, but nothing worked:
1. Copied the web.xml from jakarta-tomcat-4.1.30/webapps/examples/WEB-INF
to jakarta-tomcat-4.1.30/webapps/users/pkhann1/WEB-INF and stopped and started the server, but it didn't work.
2. Tried to add the import page statement in the dates.jsp, but it didn't work either.

Any help would be really appreciated.

Thanx for your help in advance

Since you copied the files, did you copied classes belong to a package. If so, you have to copy the .class file in the last folder of the package. I have been compiling classes in the classes folder but if its is part of package you have (or at least I have had to )move the .class file to the last folder in application for the package declaration found in my class.

If your application is accessing an web.xml file parameters make sure they correspondes with the correct entries, also.
