Java Exception Handling Framework
The framework provides a well-designed exception methodology, which could work on all kinds of Java applications. Salient points of the methodology are:

. Propagation of exception context across process boundaries.

. Separation of exception message text from the source code into message repository based on
  logical layers of application. This allows different layers to attach different and more appropriate
  message with the exception.

. Generation of unique trace number for tracing exception path when exception is logged to file.
