Tomcat and JSP: Unable to compile class, cannot resolve to a type

[tfrawley]

I have installed Tomcat 6.0.18 and JDK 6u10.

The tomcat server works fine except when I attempt to use a class
file.

The physical path to the test site is: C:\Tomcat6\webapps\test

I placed a file named "index.jsp" in the above site with the following
contents:

<%@ page language="java"%>

<%
test.Hello h = new Hello();
h.run();
%>


I used javac to compile the following class (javac -d Hello.java):

package test;
public class Hello{
public void run(){
System.out.println("Hello World");
}}


and placed the class file in: C:\Tomcat6\webapps\test\WEB-INF\classes

When I open the site I get:

org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 4 in the jsp file: /index.jsp
test.Hello cannot be resolved to a type
1: <%@ page language="java"%>
2:
3: <%
4: test.Hello h = new Hello();
5: h.run();
6: %>
7:


An error occurred at line: 4 in the jsp file: /index.jsp

1: <%@ page language="java"%>
2:
3: <%
4: test.Hello h = new Hello();
5: h.run();
6: %>
7:


This seems so simple but it refuses to work. What am I doing wrong!?!?

The second error is because you need:

test.Hello h = new test.Hello();

The first error is because the class file should be in:
C:\Tomcat6\webapps\test\WEB-INF\classes\test

Fix both and you should run.
