As mentioned in your other posts on the same question Shiva, jBPM5 includes the web-based editor - Designer (http://www.jboss.org/jbpm/components/designer) but it is specific for creation/editing of BPMN2 processes. I do not think there is a web-based editor for jPDL. Designer does not have functionality to export a BPMN2 process to jPDL but contributions are welcome.
