Hi Leo,
It is possible to use the LW HTTP server that is shipped with Java SE
6, which is what JAX-WS uses internally.
MyApplication app = ...
HttpHandler h = RuntimeDelegate.createEndpoint(app,
HttpHandler.class);
https://jsr311.dev.java.net/nonav/javadoc/javax/ws/rs/ext/RuntimeDelegate.html
#createEndpoint%28javax.ws.rs.core.Application,%20java.lang.Class%29
Then you can wire up HttpHandler to an HttpServer as you desire.
I do not know how many simultaneous JAX-RS requests can be handled. It
can depend a lot on your application and depend on the underlying HTTP
implementation. I suspect that Grizzly scales a lot better than the LW
HTTP server, because the former has been designed to scale using non-
blocking techniques (less threads can server many concurrent requests)
and Grizzly is used in GlassFish.
You can create a Grizzly adapter doing a similar thing to the above:
Adapter a = RuntimeDelegate.createEndpoint(app, Adapter.class);
Or you can use the Grizzly servlet support and use the Jersey
ServletContainer.
My recommendation is if you want a low footprint service that is
highly-scalable then use Grizzly.
Paul.
