    How to use ServiceInvoker?

      hi

       

      In my project,

      a service is called by using ServiceInvoker.

       

      When a service is called from ServiceInvoker, the service runs second times.

       

      The first calling returns a normal value to the HTTP client.

      And ServiceInvoker puts log in between the first calling and second calling.

       

      I want to call service only once.

       

      Any suggestions would be greatly appreciated.

       

      thanks.

          You have declared your second service as RequestResponse, but you are not responding from the action pipeline. The SystemPrintln action does not respond by itself. Add another action and return a Message back and it would work only once.
