Explain the role of a servlet container in the deploying of a web service and the execution of a client request.

What will be an ideal response?


When the service is created, a tool called wsdeploy creates the skeleton (or tie) classes from the service implementation. When the service is deployed in a servlet container, it is supplied with the servlet name and WSDL description, its class and skeleton classes. The WSDL contains the URL of the end point.

Client SOAP request messages are addressed to the URL of the service where a dispatcher uses the name of the method in the Action header to locate the appropriate skeleton.
The skeleton is given a SOAP request from which the arguments are extracted, these are used to call the corresponding method in the servlet. When the result is returned, it translates these back into a SOAP reply message.
