Now in its 4th year, the DDD Exchange has become one of the focal points of the DDD community. Each year, DDD thought leaders come together with 125 practitioners and enthusiasts for a truly interactive session where we delve into the tricky questions.

The LJC currently has circa 2000 members. It was founded by Barry Cranford of RecWorks Ltd. The LJC is organised and run by Barry Cranford, Martijn Verburg and Ben Evans along with a committee of passionate Java enthusiasts.
