Access bean error, urgent.

Question

I want to access a bean from my JSP. I am using Tomcat 4.1.
I put my class file in /web-inf/classes. Please tell me what's wrong?
This is the part in my jsp:
<jsp:useBean id="myBean" scope="session" class="MyBean" />This is the error message
The server encountered an internal error () that prevented it from fulfilling this request.
exception :
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 50 in the jsp file: /index.jsp
Generated servlet error:
    [javac] Compiling 1 source file
D:\Tomcat\work\Standalone\localhost\myApp\index_jsp.java:98: cannot resolve symbol
symbol  : class MyBean
location: class org.apache.jsp.index_jsp
      MyBean myBean = null;     This is my Bean class
public class MyBean
    static final String BEAN_INFO = "MyBean";
    public MyBean()
    public String getBeanInfo()
       return BEAN_INFO;
}

Answer 1

If you are using jdk1.3, then add this directive to
your jsp.
<%@ page import="MyBean" %>
And if you are using jdk1.4 then you need to put your
bean in a package and use,
<jsp:useBean id="myBean" scope="session"
class="package_name.MyBean" />AH HAH! That's why the first version doesn't work for me! I'm using JDK 1.4.1! But the books I've been reading cover 1.3! I was wondering about that! (Why is Java never backwards compatible?)
Don't forget to mention that the package has to be in the correct package directory/folder. In this case:
WEB-INF/classes/package_name/MyBean.class
It may be obvious for Java Gurus, but it bears repeating for us newbies!
