Last summer, there was one particular Summer of Code project that I was interested in : Java/Perl Integration, and seeing this years entrants made me wonder how that one finished..
So I followed the link to CPAN and found An example of using Java RMI in Java::Import, which was uploaded in January, months after last years SoC concluded.
Good work that man.. hopefully somebody, even me, if an upcoming aviation data project using Java Messaging, will pick up the ball and polish it for production use
