Provider (Jakarta EE Platform API)

Type Parameters:

T - The type of the request
```
public interface Provider<T>
```
Service endpoints may implement the Provider interface as a dynamic alternative to an SEI.
Implementations are required to support Provider<Source>, Provider<SOAPMessage> and Provider<DataSource>, depending on the binding in use and the service mode.
The ServiceMode annotation can be used to control whether the Provider instance will receive entire protocol messages or just message payloads.

Since:

1.6, JAX-WS 2.0
