Hibernate Configuration Resource Loading Problems

It is one of the very common exception thrown when you start setting up the environment for hibernate application. hibernate.cfg.xml is the default configuration file for defining the hibernate database configurations and mappings. This file has to be copied in the classpath directory. In this scenario, you always keep this file under the “src” folder of your source. If you move to the different folder, you have to specifiy the path while loading the file. The following is the exception thrown when the file is not found.

[code]
