Solution:

Cause/Solution:

The most common error that I faced till now was due the silly mistakes in the application-context.xml files. Be careful about your change in the config files rather try to do step by step instead of all in once. That is why I personally do not prefer the xml-based configurations and rely generally on on java-based configurations.
