Servlet 3 - async-mode - onComplete not tirggered when JSP is
dispatched
------------------------------------------------------------------------
Key: WFLY-4352
URL: https://issues.jboss.org/browse/WFLY-4352
Project: WildFly
Issue Type: Feature Request
Components: Web (Undertow)
Affects Versions: 8.2.0.Final
Reporter: Günther Grill
Assignee: Stuart Douglas
Labels: async, asynchronous, jsp, servlet
Attachments: AsyncServlet.war
When a JSP is dispatched in a Async-Servlet, the {{AsyncListener#onComplete}} is never
triggered.
{code:title=AsyncServlet.java|borderStyle=solid}
@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");
}
