Hi Pulasithi, Looks very good.
WRT The BPEL epr, it would mostly be a fixed endpoint with a parameterized host/ip (ex:- https://{@host}:{@port}/services/BPELService. But, supporting a registry endpoint is also a worthwhile addition. Please add the the parameterized URL as an example too, so that people will realize that's possible. WRT regards to these, - Optional - Define the location to store the response - Optional - Define whether the response should be saved as an property or artifact attribute - Optional - Define the name of the property or attribute to store the response Can we use an xpath like syntax to describe where to save the response and another proper XPath to extract a value from the response? Thanks, Senaka. On Fri, May 31, 2013 at 10:00 AM, Pulasthi Supun <[email protected]> wrote: > Hi All > > I am working on the $subject.
