I am using Tomcat 4.0 on windows 98, when I try to use my bean class from jsp program, I get package not found error. I read/followed all the similar problems in the forum but still have not been able to solve the problem.
The error I get is as follows:
==============================
type Exception report
message Internal Server Error
description The server encountered an internal error (Internal Server Error) that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: Unable to compile class for JSPNote: sun.tools.javac.Main has been deprecated.
D:\Apps\Apache\Tomcat4.0\work\Standalone\localhost\cartapp\handoff1$jsp.java:3: Package com.cartapp.user not found in import.

Contents of the jsp file

You'll get better Tomcat help in the Tomcat forum, so I'm moving this post there.
Btw, you win 2 gold stars for an exemplary question - specific, to the point, with all the necessary information for people to provide the best level of help. I'm rushed right now so I can't research your question, but if no one has answered by noon today I'll take a shot at it myself.

my bean class - User - is at:
D:\Apps\Apache\Tomcat4.0\webapps\ROOT\WEB-INF\com\cartapp\user

I think you want to put your user class in:
D:\Apps\Apache\Tomcat4.0\webapps\ROOT\WEB-INF\classes\com\cartapp\user
Also, you don't need to have the "..\Tomcat\.." directories in your classpath when running Tomcat: it will automatically discover and add everything it needs to the classpath.

Also, don't put the JSP in the Web-INF directory. It should be one level higher, so you want to put it in this directory:
D:\Apps\Apache\Tomcat4.0\webapps\ROOT

Rob,
Thanks for your response.
Further to your recommendations, I did the following:
1. Moved the User class to D:\Apps\Apache\Tomcat4.0\webapps\ROOT\WEB-INF\classes\com\cartapp\user
2. changed my classpath to CLASSPATH=;.;F:\ola\progmn\JAVA\pkgs;D:\Apps\Apache\Tomcat4.0\common\lib\servlet.jar
3. Moved my jsp to D:\Apps\Apache\Tomcat4.0\webapps\ROOT\cartapp. In addition I changed the context to this directory in the SERVER.XML file.
After restarting the computer, I got this error (class not found):
===========================================
