I want to clarify the situation with a simpler example.
I have created a war with 2 servlets, without a web.xml. So war contains
only 2 classes (for each servlet).
One servlet is annotated as:
@WebServlet(value = "/async", asyncSupported = true)
Other is annotated as:
@WebServlet(value = "/sync")
Both overrides the service method with this code:
resp.getWriter().print("async=" + req.isAsyncSupported());
I am deploying this to Tomcat 7.0.21 running on JDK 1.6.0_27 on Linux
(ubuntu 10.04 x32) with APR connector.
When I call /sync and /async, both of them displays async=false
