Lijin, I am having a similar problem.

I am trying to run examples from the Deitel Java: How to program (6th ed.), chapter 27, and it seems to occur whenever the application classes are not stored in the WEB-INF/classes directory, but in subdirectories to it.

Have you solved your problem?
Could you help me ??

Thanks in advance!
