Hi Jianwu,

Yes,that would be useful for my research (Interoperability between
scientific workflow ) and if you can send me any documents or papers
related to this KeplerWebService I will appreciate that also.


I have another question for you,

I tried to import a web service in Kepler(the wsdl is attached), this
service provide for operation add, subscribe, renewSubscription, and
unsubscribe. I chose subscribe operation and then I clicked the Commit.
I tried to use String Constant input type but this input allow me to
insert just only one string but actually the input type for this
operation should be several parameter. I used the same web service in
Triana workflow and Triana allow me to use input unit called WSTypeGen
that configure all parameters as you see in the second attachment file.
I don't know which input type in kepler should I use to provide me with
same result.

Cheers,

Ahmed
