Re: WSDL2RMI ???

Hi Barry,

Please look at
http://java.sun.com/webservices/docs/ea2/tutorial/doc/JAXRPCxrpcc3.html#64941.
This part of the tutorial talks in detail about starting from a WSDL
document.

Feeding this file along with config.xml file to xrpcc tool will also
generate a remote interface for you. You can then implement this
interface and generate ties to deploy this web service. However since
JAX-RPC does not guarantee round-trip mapping, WSDL generated by feeding
the remote interface to the tool may not match original WSDL.

The typical usage of a WSDL document generated by xrpcc tool is to
expose the web service by publishing it's WSDL in a public registry.
Since the hello example demonstrates the JAX-RPC concepts, it is not
using the WSDL in that sense.

After deploying your service, did you try verifying by specifying the
service endpoint in a browser ? It should show all the ports supported
by your service endpoint.

Thanks for your interest in JAX-RPC.

Regards,
-Arun
