I am working on project which uses JFreeChart libraries and I now I need to implement Hibernate in it as well. The problem I am having is that the Hibernate gets stuck at the resource mapping when I try to execute. It simply says "Cannot parse......". The program is written inside a package, but when I transfer the classes outside the package to the default package all works fine and the program functions as it should. Can anybody explain me what the problem is, I am giving the correct path in the configuration file, but still it just doesn't work inside the package.
