We tested the openESB 2.3 for linux and it made us go back to Sun’s release of this amazing tool. openESB is not perfect yet. I have problems with viewing debry db (I know this not esb issue but still it fails) and friend of mine had to install JBI plugins by hand… so that was serious fail. Another friend of mine said that on mac everything works like harm. I believe him. I know it is hard to find download page with this software so I will provide a link here :) Download GlasshFish ESB 2.2
