I am new to boomi .This is what some complex requirement to figure out.Some one can help on this .
Nagamani Kummari. Do you mean that a client is calling a webservice in Boomi and you expect a respone back to the client ? Or do you "simply" want to execute a webservice from within Boomi ?
Case a) Create a process using a web services server start shape so it can act as a listener. At the end of your process you can use a Return Documents shape to sent a response back to your client calling the service. To try you can use a simple Message Shape to create a sample response XML which is returned via the Return Documents shape.
Case b) You can use the HTTP Client connector shape to execute HTTP(s) calls
