Class | Description |
---|---|
HttpContext |
HttpContext represents a mapping between the root URI path of a web
service to a
HttpHandler which is invoked to handle requests
destined for that path on the associated container. |
HttpExchange |
This class encapsulates a HTTP request received and a
response to be generated in one exchange.
|
HttpHandler |
A handler which is invoked to process HTTP requests.
|
The portable deployment is done as below:
Endpoint
objects for an
application. The necessary information to create Endpoint objects
may be got from web service deployment descriptor files.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.Endpoint.publish(HttpContext)
. During publish(),
JAX-WS runtime registers a HttpHandler
callback to handle incoming requests or
HttpExchange
objects. The HttpExchange
object encapsulates a HTTP request and a response.
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):
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. @preDestroy on instances 2. Endpoint1.stop() ... 3. EndpointN.stop()
