I am currently implementing dbc for java that is 100% dource compatible and
doesn't rely on
'code in comments' techniques.

I will provide a simple java package containing the framework and processing
tools.

It uses the new Annotation facility of Java 5.0 and is VERY simple to use
and powerful.

Having tried many other frameworks, ie jContractor etc I have found this
technique
superior.

Currently in beta, and being made 'commercially robust',
keep an eye here for when it available.

Please let me know if you are at all interested:
