Hello. I'm trying to make a simple hibernate setup, but i encounter an error when i start the server (Apache).

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.
