New issue 650 by [email protected]: Guice can't create async servlet
http://code.google.com/p/google-guice/issues/detail?id=650
I've connect Guice to my project, write web.xml and everything gone right
until I wan't to realize async servlet. I using Tomcat 7.0.20 and Guice
3.0. Servlets spec version is 3.0.
Test Comet servlet:
@Singleton
@WebServlet(name = "comet", urlPatterns = {"/comet"}, asyncSupported = true)
public class CometServlet extends HttpServlet {
private class TestThread implements Runnable {
private AsyncContext context;
public TestThread(AsyncContext ctx) {
context = ctx;
}
@Override
public void run() {
try {
Thread.sleep(5000);
context.getResponse().getWriter().write("TEST!");
} catch (InterruptedException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
AsyncContext ctx = req.startAsync(req, resp);
new Thread(new TestThread(ctx)).start();
}
}
Servlet created, it placed at "/comet" path, but async not working and
error was printed:
HTTP Status 500
java.lang.IllegalStateException: Not supported.

com.google.inject.servlet.ManagedFilterPipeline.dispatch(ManagedFilterPipeline.java:122)
com.google.inject.servlet.GuiceFilter.doFilter(GuiceFilter.java:110)
I think this is bug, because I write web.xml directly without Guice and it
working as expected.
