Hi, I intend to develop a portlet which will allow to execute a workflow of jobs (not very complex needs, a simple DAG would be enough). However, at this point I am baffled by the huge number of options and combinations out there (Karajan, BPEL, Pegasus,...).
I would like to achieve sth similar to what can be done with CoG's TaskGraph (object oriented and simple), but my preference right now would be to use the Condor API (the WS Schedd API as oposed to command line tools like condor_submit_dag, my language of preference is Java). If anyone has implemented such a portlet, or a similar one, I'd be grateful to be sent a link to look at it. Suggestions on proven or likely-to-work approaches are also very welcome. Thank you for your help, Matt
