Servlet class not found error deploying a WAR on Web Logic Server 8.1

Question

I'm re-deploying an updated web application to a web logic server, but when I navigate to the login page of the web application to test it, I get a class not found error for my login servlet. I have both the web.xml and the weblogic.xml descriptors in my WEB-INF directory, and all of my compiled classes are in the WEB-INF/classes directory, is there something else I'm missing? Any help would be much appreciated.

Thanks for the response. Here's the web.xml file:
<?xml version="1.0" ?>

None of the classes are in a package (I know it's not the best idea, but I didn't write these, I'm just doing some updates). So the file structure is pretty much just WEB-INF/classes/
At the moment I've got a fix by just putting the entire project (not in any sort of archive) on the server itself instead of deploying it as a WAR, any thoughts on why the WAR isn't working would be much appreciated though.
