Hi!

I am new to web-services and required to know, a couple of things about them:
1. How do I write a web-service and enable it, so that someone (For the time-being, I) can invoke it.
2. How do I invoke a web-service and what are the parameters, I require from the creator of the web-service to invoke it?
3. How do I use UDDI to search for "all vendors that provide shipment from a source to a destination" to get results like FedEx, APS, etc?
4. I am also confused about where JAXB and JAX-RPC fit into the picture of creating a web-service.

I will be most obliged, if anyone could give me pointers in this direction.

Thanks and regards,
Pramod Mundhra

Web Services Handbook

It covers SOAP, WSDL, UDDI, JAX-RPC ...

Two really quick and easy ways to invoke a web service:
1) MindReef SoapScope. A great tool to have when working with web services.
2) WSIF. A very easy to use framework for dynamically invoking web services.
