Request response as xml

Question

I have been given an xsd file and asked to create a web service whose request/response is based on this provided xsd.
and the requirement is to have request/response of web service in xml doc. This complete XML cannot be a sent as string.
So, please let me know how to acheive this. i.e how to inject the required xml structure in the web service response.

how would i pass on the request on to web service -From jaxb classes i can send the resquest in an xml doc to the web service? or how? and likewise the result ftom web service to jaxb classes?Answer of your question is XML Marshaling and Unmarshalling will be used for the above purpose.
The Java Architecture for XML Binding (JAXB) provides a fast and convenient way to bind between XML schemas and Java representations, making it easy for Java developers to incorporate XML data and processing functions in Java applications. As part of this process, JAXB provides methods for unmarshalling XML instance documents into Java content trees, and then marshalling Java content trees back into XML instance documents. JAXB also provides a way to generate XML schema from Java objects.

Client app. will use these

Just go through tutorial given in my previous and current post. Use any good IDE to develop, I prefer NetBeans first and then Eclipse.
Below two links will help you to build and consume a web service using NetBenas IDE.
