AtmosphereFramework exception java.lang.IllegalStateException: Not supported

Question

I am using Atmosphere in my grails application. every thing is fine when running application from my IDE (IntelliJ Idea). but when I deploy it to tomcat (7.0) following exception raises:

2013-07-08 09:07:19,118 [ajp-nio-8009-exec-13] ERROR cpr.AtmosphereFramework  - AtmosphereFramework exception

myservlet config in web.xml is:

<servlet>
        <description>MeteorServlet</description>
        <servlet-name>MeteorServlet</servlet-name>
        <servlet-class>org.grails.plugin.platform.events.push.GrailsMeteorServlet</servlet-class>
        <init-param>
            <param-name>org.atmosphere.cpr.broadcaster.shareableThreadPool</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <param-name>org.atmosphere.cpr.broadcaster.maxProcessingThreads</param-name>

        </init-param>
        <load-on-startup>0</load-on-startup>
        <async-supported>true</async-supported>
    </servlet>

usage is

var receivedOrders = new Array();
    var grailsEvents = new grails.Events("${rootPath}",
    {
        transport: 'sse',
        fallbackTransport: 'long-polling',
        timeout: 10000,
        onMessage: function(data){
            try{
                if(data.responseBody.length > 0){
                    var order = jQuery.parseJSON(data.responseBody).body;
                    if(order.id){
                        if (receivedOrders.indexOf(order.id) == -1) {
                        receivedOrders[receivedOrders.length] = order.id;
                        var url = "<g:createLink controller="orderAdministration" action="orderNotification"/>";
                        $.ajax({
                            type: "POST",
                            url: url,
                            data: { id: order.id }
                        }).done(function (response) {
                                    if (response != "0") {
                                        $.msgGrowl({
                                            type: 'info', sticky: true, 'title': '${message(code: 'order.notification.title')}', 'text': response, lifetime: 5000
                                        });
                                    }
                                });
                        }
                    }
                }
            } catch (e) {
                // Atmosphere sends commented out data to WebKit based browsers
            }
        }
    });

    grailsEvents.on('order_event', function(data){});

it seems some thing is wrong with tomcat configuration. any idea?

EDIT:

I have tested it. but does not work.

the problem occured because I have provided options in grails.Events. by changing to this, exception solved.

var receivedOrders = new Array();
    var grailsEvents = new grails.Events("${rootPath}");

    function handleOrderEvent(data){
        try{
            if(data.id){
                if (receivedOrders.indexOf(data.id) == -1) {
                    receivedOrders[receivedOrders.length] = data.id;
                    var url = "<g:createLink controller="orderAdministration" action="orderNotification"/>";
                    $.ajax({
                        type: "POST",
                        url: url,
                        data: { id: data.id }
                    }).done(function (response) {
                        if (response != "0") {
                            $.msgGrowl({
                                type: 'info', sticky: true, 'title': '${message(code: 'order.notification.title')}', 'text': response, lifetime: 5000
                            });
                        }
                    });
                }
            }
        }catch (e) {
        // Atmosphere sends commented out data to WebKit based browsers
        }
    }

    grailsEvents.on('order_event', handleOrderEvent, {transport:'long-polling', fallbackTransport:'polling'});

but still no event is propagated to client!

I have an apache webserver in front of tomcat. events fired in services but not in javascript.

There is an other response from JF Arcand (the creator of the Atmospehere framework) : http://atmosphere-framework.2306103.n4.nabble.com/org-apache-catalina-connector-Request-startAsync-Not-Supported-td4651994.html

you either needs to add in your web.xml

<servlet-class>org.atmosphere.cpr.AtmosphereServlet</servlet-class>
<async-supported>true</async-supported>

to enable Servlet 3.0, or add

 <init-param>
      <param-name>org.atmosphere.useNative</param-name>
      <param-value>true</param-value>
  </init-param>

As async-supported is already defined, you should try to set the org.atmosphere.useNative to true
