The core PNM application has been completed and the code committed to
the SVN. Now, I will focus more on the supplementary services

As of now, i am saving the context using in memory data
structures,encapsulated by a thread safe singleton.
later, the data will be stored using JPA and Hibernate as persistence
provider in the database.
