Failed to call a service to trigger/start a Process from portlet

Dear All,

I am using webMethod 7.1.
Now I try to create a portlet which submit a Process.
I created a service at Devloper first and which is no problem when I test it.(Able to create new Process). so, both Process and Service should be no problem.

But when I create a portlet and call this service from it. It was failed and got the followings error, does anyone know what is the reasons behind it? Thanks.

Can you please provide more information, such as:

Do you have any document you want to publish or no?

Does the flow service your using have Input/output fields?
Does those fields exist on your portlet?
are this field bound correctly?

I think you are trying to start your process from a task view.

Did you check your ‘endPoint’ value.
