Developing website for GunGame5 + Achievements

[Humbie]

Hi,

I'm currently in the process of developing a JSP website which can already read GunGame5 winnersdata.db file and the Gungame5 Achievements playerpairs.db & playerranks.db file.
What I am having trouble with at the moment is the UnPickling of the GunGame5 Achievements database.db file and am hoping to find some help over here.

I am developing using the Java language (JDK6u16) with Jython 2.5.0 (Java implementation of Python) as an included library.
I don't know if any of you guys have Java experience, but I am always seeing a NullPointerException when trying to load the db-file through cPickle.
All I need help for is the ability to read the database.db file into a ConcurrentMap (as Jython's cPickle does).

If anyone is willing to help/contribute, it would be greatly appreciated.
