Could you please help me to resolve this Error.?

Did the server start without errors? Is your web.xml file set up for the srtuts2 filter to handle .action prefixes. At first glance what you've posted looks correct, so I think the problem must be in other files.

I wrote: Firstly Yes,The server started successfully without any errors.
Secondly Yes, The web.xml file is configured to have an entry for FilterDispatcher.class file.It is also handling .action prefixes.

Can you tell me in which other files should the error be,Because the console output shows no Errors.

Please help me to resolve the errors.



Hi Tom,need your Guidance to resolve the above error.

Ok, if you're confident that your web.xml file is set up correctly, how about your application.xml file. Does it have your contxt root specified correctly?

<context-root>StrutsHelloWorld</context-root>

I think is what you will want.

My interpretation: There are only 2 .xml files available.one is struts.xml file and web.xml file.
Which is the application.xml file ?? Is this an additional file to be configured ,why do you need an entry of
<context- root>StrutsHelloWorld</context-root> in this file.

Please explain ??

I believe the application.xml file is a standard part of the j2ee architecture to allow you to create a deployment descriptor for your application. I know in my application its where I supply the context root for my application and I'm wondering if you're getting that 404 error because of it.

[Bear Bibeault]

application.xml is not standard -- there is no standard for how containers declare contexts. That's container-specific. For Tomcat, it's server.xml*.

As of Tomcat 5, it's best practice to not put contexts in server.xml, but to create separate context files. See the Tomcat documentation for more information.

[Tom Rispoli]

I stand corrected. Guess I've spent too much time using Sun appservers.

[Deepak Lal]

Please tell me how to go about in resolving the 404 error.

[Tom Rispoli]

For some reason your struts2 filter isn't getting called, but the request does appear to be reaching your application server. You believe that the sever is starting correctly and that your web.xml file is set up correctly. The next thing that I would be suspicious of is your deployment descriptor. I don't know how this should be set up for Tomcat but Bear gave you some pointers on what to read up on in his posting.

I'm not able to resolve this...
Please need help ranchers.

[Tom Rispoli]

Posting your web.xml file might help, posting your deployment descriptor files might help as well (although they are probably tomcat specific so I may not be able to make much sense of them but others may be able to). Also, try changing your URL and see if you can get a different result. See what happens if you try to access

http://localhost:8080/act/cooler.action

or

http://localhost:8080/cooler.action
