Tomcat - Struts app Startup Error

[Joe San]

Guys,

A Struts 2.x.x web app gives me startup errors.

From the stack trace above, I could see that this is caused due to some incompatibilities in the Struts jar file version. But how to get rid of this error? I want to use this particular version of Struts.

Seems like this is an issue with xwork. In my Maven pom.xml for the project, I do not have a dependency defined to xwork 2.0.4.
But the project fails simply because it cannot download this xwork 2.0.4.jar. There are two questions here:

(1) Why the heck is Maven not able to download the jar from Maven repo? I'm sure that I'm not behind a proxy.
(2) Why will it ever need a jar which I have not added as a dependency?

The stack trace for some info...

Seems more like a Maven issue. Mods please move this to the Maven forum:

I did try to debug my build and seems that the error that I posted above originates more earlier in the build cycle. Here it is:

Finaly was able to resolve question 2. The xwork-2.0.4 was referrenced in the jcapcha4struts2 which I use in my project. So I had to modify it and rebuild the jcaptcha4struts2 to use xwork-core-2.2.3 and it worked finally.

Still question 1 remains unanswered, but manually downloading the jar and building the app atleast worked.
