Hi,
Sadly in JAX-RS you don't have access to AsyncContext, here is my solution. I
had to use reflection because of classloader issues...
Path("res")
public class TestResource {
private Logger log;
public TestResource() {
log = Logger.getLogger(TestResource.class.getName());
}
@GET
public void getResourceData(@Suspended AsyncResponse ar, @Context
ServletContext sc) throws NoSuchMethodException, SecurityException,
IllegalAccessException, IllegalArgumentException, InvocationTargetException {
log.log(Level.INFO, "In thread {0}", Thread.currentThread());
Method methodGetContextHandler =
sc.getClass().getMethod("getContextHandler");
Object contextHandler = methodGetContextHandler.invoke(sc,
null);
Method methodGetServer =
contextHandler.getClass().getMethod("getServer");
Object server = methodGetServer.invoke(contextHandler, null);
Method methodGetThreadpool =
server.getClass().getMethod("getThreadPool");
Executor threadPool = (Executor)
methodGetThreadpool.invoke(server, null);
Runnable run = new Runnable() {
@Override
public void run() {
Logger log = Logger.getAnonymousLogger();
log.log(Level.INFO, "In thread {0}",
Thread.currentThread());
ar.resume("it works!");
}
};
threadPool.execute(run);
}
}
The JPA context has a warp() function, it would be cool if ServletContext could
have something similar: sc.wrap(Server.class) to get the underlying server
class.
