Tomcat Java Classes
I am trying to get a simple JSP page working under Tomcat and failing miserably.
Error message:
Code:
HTTP Status 500 -

exception

The JSP page (index.jsp):
Code:
<%@page import="bll.User"%>
<%
User user = new User();
user.setFirstName("Some");
user.setLastName("Guy");
%>
<html>
<head>
<title>test</title>
</head>
<body>
<p><%= u.getFullName() %></p>
</body>
</html>
The User class:
Code:
package bll;
public class User
{
private String firstName;
private String lastName;
public User()
{
}
public String getFirstName()
{
return this.firstName;
}
public void setFirstName(String value)
{
this.firstName = value;
}
public String getLastName()
{
return this.lastName;
}
public void setLastName(String value)
{
this.lastName = value;
}
public String getFullName()
{
return this.getFirstName() + " " + this.getLastName();
}
}
web.xml:
Code:
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 1.2//EN" "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
</web-app>
File and directory structure:

CLASSPATH and JAVA_HOME:
Code:
dtucker@dtucker-vm:~$ echo $CLASSPATH
/usr/share/tomcat6/webapps/test/classes
dtucker@dtucker-vm:~$ echo $JAVA_HOME
/usr/lib/jvm/java-6-openjdk
Does anybody have any ideas? I can provide any other information that might be needed.
