/**
Provides HTTP SPI that is used for portable deployment of JAX-WS
web services in containers(for e.g. servlet containers). This SPI
is not for end developers but provides a way for the container
developers to deploy JAX-WS services portably.
The portable deployment is done as below:
- Container creates {@link javax.xml.ws.Endpoint} objects for an
application. The necessary information to create Endpoint objects
may be got from web service deployment descriptor files.
- Container needs to create {@link javax.xml.ws.spi.http.HttpContext}
objects for the deployment. For example, a HttpContext could be
created using servlet configuration(for e.g url-pattern) for the
web service in servlet container case.
- Then publishes all the endpoints using
{@link javax.xml.ws.Endpoint#publish(HttpContext)}. During publish(),
JAX-WS runtime registers a {@link javax.xml.ws.spi.http.HttpHandler}
callback to handle incoming requests or
{@link javax.xml.ws.spi.http.HttpExchange} objects. The HttpExchange
object encapsulates a HTTP request and a response.
{@literal
Container JAX-WS runtime
--------- --------------
1. Creates Invoker1, ... InvokerN
2. Provider.createEndpoint(...) --> 3. creates Endpoint1
configures Endpoint1
...
4. Provider.createEndpoint(...) --> 5. creates EndpointN
configures EndpointN
6. Creates ApplicationContext
7. creates HttpContext1, ... HttpContextN
8. Endpoint1.publish(HttpContext1) --> 9. creates HttpHandler1
HttpContext1.setHandler(HttpHandler1)
...
10. EndpointN.publish(HttpContextN) --> 11. creates HttpHandlerN
HttpContextN.setHandler(HttpHandlerN)
}
The request processing is done as below(for every request):
{@literal
Container JAX-WS runtime
--------- --------------
1. Creates a HttpExchange
2. Gets handler from HttpContext
3. HttpHandler.handle(HttpExchange) --> 4. reads request from HttpExchange
<-- 5. Calls Invoker
6. Invokes the actual instance
7. Writes the response to HttpExchange
}
The portable undeployment is done as below:
Container
---------
1. {@literal @}preDestroy on instances
2. Endpoint1.stop()
...
3. EndpointN.stop()
