Class not found error when running deployed app

[gturek]

Inside my ear, some classes in the war depend on a class which is packaged up into a utilities jar file (not the ejb jar file). I assumed that i'd be sufficient to add this jar file to the war's META-INF/MANIFEST.MF file, but it does not work. I get a   java.lang.NoClassDefFoundError: Could not initialize class ..... error when running the application. I am a bit at a loss. I am running JBOSS 4.2.3

I should mention that the classes that are having problems are servlets, ant the error is:

1:17:59,317 ERROR [[LogFileServlet]] Servlet.service() for servlet LogFileServlet threw exception
java.lang.NoClassDefFoundError: Could not initialize class nz.co.niwa.core.utils.FileUtils

Aha, it turns out that there were further dependencies not being satisifed, ie the "missing" class was there, but some of its dependencies were not. Misleading error message
