Having trouble deploying web app with AsyncListener
Hi,
I am using WildFly 8.2 on JDK 1.8. I have an AsyncListener defined, source code builds fine. But on deployment I get the following error :
2015-02-02 20:53:52,078 INFO [org.jboss.as.server.deployment] (MSC service thread 1-1) JBAS015876: Starting deployment of "chapter3.war" (runtime-name: "chapter3.war")

My Listener class is looks like :
package com.redhat.chapter3;
import java.io.PrintWriter;
import javax.servlet.AsyncEvent;
import javax.servlet.AsyncListener;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebListener;
/**
* Application Lifecycle Listener implementation class ExampleAsyncListener

*/
@WebListener
public class ExampleAsyncListener implements AsyncListener {
/**
* Default constructor.
*/
public ExampleAsyncListener() {
// TODO Auto-generated constructor stub
}
/**
* @see AsyncListener#onComplete(AsyncEvent)
*/
public void onComplete(AsyncEvent arg0) throws java.io.IOException {
// TODO Auto-generated method stub
System.out.println("AppAsyncListener onComplete");
}
/**
* @see AsyncListener#onError(AsyncEvent)
*/
public void onError(AsyncEvent arg0) throws java.io.IOException {
// TODO Auto-generated method stub
System.out.println("AppAsyncListener onError");
}
/**
* @see AsyncListener#onStartAsync(AsyncEvent)
*/
public void onStartAsync(AsyncEvent arg0) throws java.io.IOException {
// TODO Auto-generated method stub
System.out.println("AppAsyncListener onStartAsync");
}
/**
* @see AsyncListener#onTimeout(AsyncEvent)
*/
public void onTimeout(AsyncEvent arg0) throws java.io.IOException {
// TODO Auto-generated method stub
System.out.println("AppAsyncListener onComplete");
ServletResponse response = arg0.getAsyncContext().getResponse();
PrintWriter out = response.getWriter();
out.write("Timeout Error in processing");
}
}
Can somebody please help?
TIA
