Echo ws bottom-up method

Following the bottom-up development method wizard we can create a new Web Service in a few moments.

We start from a GreenVulcano^® ESB service "echo" that simply returns the user input as well as is.

Once launched wizard and inserted all parameters, VulCon^® creates the WSDL file that describe our service.

This is the "echo_ws.wsdl" generated:
