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. The guys from struts mailing list say that the error is server specific, so i decided to report it here. 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.
