Hi Ivelin, Actually I believe it is possible to have continuations in pure Java -- using bytecode rewriting -- however this approach is quite intrusive and its effect on performance and code-size is not insignificant (see: http://www.cs.kuleuven.ac.be/~tim/MOS/brakes.html). Nevertheless the performance of such instrumented code would likely still be significantly faster than interpreted Rhino. I think it would be interesting to prototype such an approach. If someone is interested in doing this for Cocoon, I suggest they contact the authors of Brakes and see if they might be interested in contributing their code to Apache. Given that I think it would be fairly straightforward to set up a pure Java flow layer similar to what Ovidiu has done with JavaScript.

At this point, the only reasonable question that I can ask is, if it is possible to consider providing the continuation capabilities within the Actions instead of promoting JavaScript as another language supported by Cocoon. My reasoning is that for the size and scalability of the web applications that I am dealing with, I wouldn't bet too much on a loosely typed and non-compiled language. If provided, however, I may seriously consider using a more sophisticated paradigm for flow control within my actions. I hope to learn more from this thread.
