Answer 1

Hello Raimund,
Thanks for your reply.
Yes I am executing these components on the discovery server. It's actually part of the exercises that came with the server which is Composite Tool Box.
When I am deploying the application without converting the Application Service to a Web Service everything works fine when I am trying to convert it to a Web Service as required by the Visual Composer part of the exercise, I am able to buld it however when I am deploying it I get the Exception.
Thanks.
