Ok, could not resist and already took a quick look. It is transactional file handling, only not quite as I'd like it (no offence). This could/should be wrapped in a JCA for the requirements we have and be able to run in CMT. So things like closing the file after the transaction completed (required in this implementation) should be done 'automagically'. http://wernli.nine.ch/web/guest/52 does this already, and 'just' needs some JBoss 'wrappers'. See http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4269511#... and http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4269883#... (sorry for the fragmentation ;-). If something works, I'll make sure to blog about it. Unfortunately the work on the ui for the profiler has to be postponed to January (also because of this and an important jBPM release) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4269903#...
