Description
When a JSP is dispatched in a Async-Servlet, the AsyncListener#onComplete is never triggered.
AsyncServlet.java
@WebServlet(urlPatterns = { "/AsyncServlet" }, asyncSupported = true)
public class AsyncServlet extends HttpServlet {
public AsyncServlet() {
super();
}
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
res.setContentType("text/html");
final AsyncContext ac;
if (req.isAsyncStarted()) {
ac = req.getAsyncContext();
} else {
ac = req.startAsync();
}
ac.setTimeout(5000);
ac.addListener(new AsyncListener() {
@Override
public void onTimeout(AsyncEvent event) throws IOException {
System.out.println("onTimeout");
}
@Override
public void onStartAsync(AsyncEvent event) throws IOException {
System.out.println("onStartAsync");
}
@Override
public void onError(AsyncEvent event) throws IOException {
System.out.println("onError");
}
@Override
public void onComplete(AsyncEvent event) throws IOException {
System.out.println("onComplete");
}
});
System.out.println("Calling JSP...");
ac.dispatch("/result.jsp");
System.out.println("After JSP call");
}
}
