How to build secure webservices using multiple xsds?

Question

Hi All,

I m in process of building webservices, but all I have is xsd's. Lots of them.

I have to build webservices using these xsds.

How do I go about creating a WSDL using multiple xsds, embedding the input/outputs from xsds into the WSDL.

Is there any tutorial , a book that details about building webservices.

Also I need to secure the webservices, which means I need to put in support for WS-sercurity in the WSDL.

Thanks all.
