Hi Bart, I haven't been much active recently, but me and Maurizio worked a lot to have Javaflow working in 2.2 last summer. The 2.2 javaflow block is based on the new common javaflow made by Torsten Curdt (http://jakarta.apache.org/commons/sandbox/javaflow/ ). This uses JCI to load classes and instrument them at runtime, while there is an ant task to instrument them at build time. The problem, back in september, was that Torsten didn't have time to release a new version of JCI, so the patch applied to have javaflow working was commented out waiting for a new release with JCI patches.
I still have a rather old version of 2.2 with all patches applied, a patched version of JCI, and javaflow, with real time reloading and re-instrumenting of classes, mostly working on it. Torsten, any news? :D Simone Bart Molenkamp wrote: > Hi all, > > Can someone tell me what the status is of the javaflow block in Cocoon > 2.2?
