Summary: AsyncListener.onComplete is not called after
AsyncContext.complete() is called
Product: Tomcat 7
Version: 7.0.4
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: [email protected]
ReportedBy: [email protected]
Using servlet 3 async features, when asyncContext.complete(); is called from an
async thread, the AsyncListener onComplete() method is not called though it
should be.
Example Servlet :
package test;
import java.io.IOException;
import javax.servlet.AsyncContext;
import javax.servlet.AsyncEvent;
import javax.servlet.AsyncListener;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* Servlet implementation class MyServlet
*/
@WebServlet(value = "/MyServlet", asyncSupported = true)
public class MyServlet extends HttpServlet implements AsyncListener {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException
{
final AsyncContext asyncContext = request.startAsync(request,
response);
asyncContext.addListener(this);
asyncContext.start(new Runnable() {
@Override
public void run() {
try {
Thread.sleep(5 * 1000);
asyncContext.getResponse().getWriter().write("Hello
world");
asyncContext.complete();
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
@Override
public void onComplete(AsyncEvent arg0) throws IOException {
System.out.println("onComplete " + arg0);
}
@Override
public void onError(AsyncEvent arg0) throws IOException {
System.out.println("onError " + arg0);
}
@Override
public void onStartAsync(AsyncEvent arg0) throws IOException {
System.out.println("onStartAsync " + arg0);
}
@Override
public void onTimeout(AsyncEvent arg0) throws IOException {
System.out.println("onTimeout " + arg0);
}
}
