GreenFire, Groovy, Shoal, iPhone integration and interview at JavaLobby

I was interviewed by Geertjan Wielenga about GreenFire and it's history - the interview was really agile - I was asked for an iPhone screenshot, and maked it during the interview... :-). If you are interested in GreenFire, come to JAX conference - I will at least introduce it during the JAX Innovation Award nomination with two slides :-) and mention some examples like Groovy integration during the Java EE 5 workshop at friday.

I will give a shortalk in the java.net area during the JavaONE as well.

Guillaume,

sure - it was the easiest way to provide a "Fluid Kernel" or "Soft Heart" functionality,

thank you for Groovy!,
