Problem using Java Bean in JSP File

[Mahesh V Yadav]

Hai All,

 

I created a small JSP File which uses a java Bean, iam using jsp1.0 Reference implementation under  win'98.

when i was accessing that jsp file it gives error message:

 

i placed my Hello.jsp in c:\jsp1.0\examples\jsp\myjsp\ directory

and i placed my Java Class File Hello.class in C:\jsp1.0\examples\WEB-INF\jsp\beans\myjsp\ directory

 

The Message is as Follows :

 

Unhandled error! You might want to consider having an error page to report such errors more gracefully

com.sun.jsp.JspException: Unknown exception: javax.servlet.ServletException:  Cannot create bean of class myjsp.Hello

**********************************************************************************************************************************************

 

My JSP File Hello.jsp is as Follows :

<jsp:useBean id="hello" scope="request" class="myjsp.Hello" />
<%= hello.getMessg() %>
 

**********************************************************************************************************************************************

  

My Hello.java Program is as Follows

 

package myjsp;

 

public class Hello {

 

        public String getMessage() {
                return "Hello World";
        } // end getMessage
       
} // end Hello class

 

**********************************************************************************************************************************************

 

Can somebody tell me where iam doing wrong, is it the right way to create a java bean or should Hello.java implement serializable

interface.

 

 

Any help would be greatly appreciated

 

Thanks a lot in Advance

 

 

Regards
