About this task
In WebSphere
® Application
Server Version 7.0 and later,
using JAX-WS, you can enable the Web Services Metadata Exchange (WS-MetadataExchange)
protocol so that the policy configuration of the service provider
is included in the WSDL and is available to a WS-MetadataExchange
GetMetadata request. One advantage of using the WS-MetadataExhange
protocol is that you can apply message-level security to WS-MetadataExchange
GetMetadata requests by using a suitable system policy set. Another
advantage is that the client does not have to match the provider configuration,
or have a policy set attached. The client only needs the binding information,
and then the client can operate based on the provider policy, or based
on the intersection of the client and provider policies. You can configure
a service provider to share its policy configuration using the administrative
console. For more information, read the following topics:

security for a WS-MetadataExchange request
