Hi David,
Neither of these return immediately:
@Path("/abc")
@Stateless
@javax.ejb.TransactionAttribute(TransactionAttributeType.NEVER)
public class BasicResource {
@GET
@Produces(MediaType.APPLICATION_JSON)
public void test(@Suspended final AsyncResponse asyncResponse) {
asyncResponse.resume(Response.ok("Hello world").build());
sleep();
}
private void sleep() {
try {
Thread.sleep(3000);
} catch (Exception e) {
}
}
}
@Path("/abc")
public class BasicResource {
@GET
@Produces(MediaType.APPLICATION_JSON)
public void test(@Suspended final AsyncResponse asyncResponse) {
asyncResponse.resume(Response.ok("Hello world").build());
sleep();
}
private void sleep() {
try {
Thread.sleep(3000);
} catch (Exception e) {
}
}
}
