Struts 1 Hello World Program

[Mallory Liz]

Hello,

I have just started learning about Struts and I have started with the Hello World Program. When I run my program I get the following error.
HTTP Status 404 -
type Status report
message
description The requested resource is not available.


Could some one kindly help me with debugging my program. I am not sure what needs to be done.

Thanks a lot in advance.

If you are just starting out, please do not use Struts 1.x. The last update of Struts 1.x was in 2008 and it will receive no further updates, including security fixes (see here). If that isn't enough reason, Struts 1.x suffers from several severe architectural problems which make the framework tedious to use and difficult to maintain.
My advice would be to use a "modern" framework, like Struts 2.x or Spring. They are much easier to use and much more productive for the developer.
