Supposing your class looks like the following:
package com.mycompany.mywebapp
public class MyClass {
}
then you need the following import directive
%@ page import=com.mycompany.mywebapp.MyClass%
or
%@ page import=com.mycompany.mywebapp.*%
Please note, i see you have your error at line 85, don't forget your %@ page
import=... % directives must be at the top of the jps, not in the code
Also, compiled class must be either in
WEB-INF/classes/com/mycompany/mywebapp/MyClass.class
or in a .jar file located in WEB-IF/lib/*.jar

I'm new to programming in JSP/Tomcat. I am kinda held back with the
following simple situation. I have database connection class that I'm
trying to import in my jsp file with no success so far (ChangePassword).
I am compiling with JDK1.4.2.08.
My JSP page is in
$CATALINA_HOME/webapps/mywebapp/
I do have a web.xml file that is correctly configured with passwords and
values to allow the application to connect to the user directory. This
is the stack trace of the error:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 85 in the jsp file: /changepw.jsp

Any ideas how to import a user-defined class in JSP, I mean where to
place the class file and is there anyother environment variable to set?
I read somewhere that if you are using jdk 1.4 and above, you need to
have package name for classes. It said to Put your webappname class in
a package, compile it and then import it like the following in your JSP
file: %@ page import=packagename.WebAppName%
Again, I am new to all of this so could you possibly help me with the
issue as well as helping me to understand the potential fix as outlined
above? I would really appreciate any help you can provide.
Thanks
