Tomcat 4.1 class problem. Doesn't identify the class.

Question

Hi
I just installed J2SDK and tomcat in windows xp. I've made jsp files and beans. The first page is customerlogin.jsp which takes user id and password in a form. It sends the request to authenticate.jsp. Would you please give me a few important steps that need to be done?
My directory structure is as follows:
C:\Tomcat 4.1\Webapps\Log -> jsps
c:\Tomcat 4.1\Webapps\Log\WEB-INF\classes\Log -> java beans
The jsp doesn't find AuthenBean class. It complains about it.
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 1 in the jsp file: /authenticate.jsp
Generated servlet error:
[javac] Compiling 1 source file

Your help would be appreciated
Thanks!

Your problem is in web.xml. Only servlet classes need to be mapped. Your bean class should not be.
****** web.xml in Log\WEB-INF is **********
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web
Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<servlet>
<servlet-name>Log\AuthenBean</servlet-name>
<servlet-class>Log\AuthenBean</servlet-class>
</servlet>
<servlet>
<servlet-name>Log\ExecuteQuery</servlet-name>
<servlet-class>Log\ExecuteQuery</servlet-class>
</servlet>
</web-app>
If you have only jsps, u mau use
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web
Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
</web-app>
Hope it works.
