Thank you, can you please show me what line indicates that the error is specific to the server but not struts?
Some ppl on the net testify that changing their xwork-core version fixes the problem. here --- On Tue, 4/26/11, Dave Newton <davelnew...@gmail.com> wrote: From: Dave Newton <davelnew...@gmail.com> Subject: Re: SEVERE: Exception starting filter struts2 To: "Struts Users Mailing List" <user@struts.apache.org> Date: Tuesday, April 26, 2011, 10:04 AM Just because ant or an ide sees a class doesn't mean the web server does when you're deploying or starting up. Almost certainly a classpath issue with the server, almost certainly not Struts, just like the exception indicates. Dave On Apr 26, 2011 8:52 AM, "alex zaim" <icid...@yahoo.com> wrote: > Hello.

It's obvious that i am missing a class. But the problem is that the class is right there where it should be. I mean, Ant sees the class and gives no compilation errors, also my IDE (Eclipse) sees the class (from the build path), but when i start the server, it gives my that error. > I assume it has to do with struts since the filter can not be initialized. > > Another interesting thing is that if i remove the jar (which contains the specific class) from the project's build path, the server will launch with no erros, but will fail when an action is triggered that uses that class. > >
