Unexpected error when running application from tomcat.

[Owais Zahid]

I have recently started using struts 2 . I am developed a web application. When i deploy the site on my tomcat 6 and start tomcat , i got the following error.

Please UseCodeTags when posting code or configuration. Unformatted code and configuration is unnecessarily difficult to read.

You can edit your post by using the button.

[David Newton]

You did not include your Struts 2 configuration file(s).

Wouldn't it make more sense to start with a plain S2 app, get that working, then continue, instead of trying to do everything at once?

Sorry for the inconvenience. David, the application was working before, i don't know why its giving me this error now.

[David Newton]

What did you change?

Try to isolate the problem by creating a small testcase and post the libs/configs for that.

[Mark E Hansen]

Are you missing the xwork-core Jar, or is it called just xwork in that version of Struts 2?
