[Error] Shared Object inside Schedule Job

[Frenda Rangga Aksara]

I try to update SO and send to client. But it shows error like this:
java.lang.IllegalMonitorStateException
        at java.lang.Object.notifyAll(Native Method)
        at org.red5.core.Application$1.execute(Application.java:142)
        at org.red5.server.scheduling.QuartzSchedulingServiceJob.execute(QuartzS
chedulingServiceJob.java:59)
        at org.quartz.core.JobRunShell.run(JobRunShell.java:202)
        at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.j
ava:525)

and my code :
this.addScheduledJob(5000,new IScheduledJob() {
            @Override
            public void execute(ISchedulingService jobs0)
                    throws CloneNotSupportedException {
                System.out.println(sendList);
                try{
                    so.setAttribute("thread", sendList);
                    so.notifyAll();
                }catch (Exception e) {
                    e.printStackTrace();
                }
    
            }
        });

it shows error like that when so.notifyAll();
Have anyone ever crush something like that?

thanks in advance

Google:
In order to use notify* or wait, the current thread needs to be the owner of the
lock on the object, in this case the 'this' object.  Either declare the function
as 'synchronized' or create a synchronized block around the notify.

hi, I have did what you have suggested, like this :

try{
                    so.setAttribute("thread", sendList);

                    synchronized (so) {

                        so.notifyAll();
                    }
                }catch (Exception e) {
                    e.printStackTrace();
                }

Correct me if I'm wrong.
it didn't show error, but my SO didn't updated or it didn't send to my client.
any idea?

thanks for replay

[Cristian Rusu]

Usually I don't call any notification
Make sure you actually create a listener o flash
When I set attribute on SO, it automatically goes to all connected clients as updated.

Yeah, when I didn't use ScheduleJob, it's run correctly. I wonder it because the scheduleJob, but I still don't know.

my listener client like this :
public function onCreationComplete(event:FlexEvent) : void {
                // setup connection code
                connection = new NetConnection();
                connection.addEventListener(NetStatusEvent.NET_STATUS, onConnectionNetStatus);
                connection.connect("rtmp:/Red5Trhread");
                connection.client = this;
                shared = SharedObject.getRemote("thread", connection.uri, false);
                shared.client = this;
                shared.connect(connection);
                shared.addEventListener(SyncEvent.SYNC, receiveVariable);
            }

public function receiveVariable(e:SyncEvent):void{
                Alert.show(shared.data.thread.toSting()+"test");
                var temp:String = shared.data.thread.toSting();
                myAC2 = temp.split(",");   
                arrayOfObject = myAC2.map(toObject);
                list1.dataProvider = arrayOfObject;

Your client code is all wrong.

You cant do all that in one single function and your stuff is out of order.

public function onCreationComplete(event:FlexEvent) : void {
// setup connection code
connection = new NetConnection();
connection.addEventListener(NetStatusEvent.NET_STATUS,
onConnectionNetStatus);

connection.client = this;
connection.connect("rtmp:/Red5Trhread");
}

public function onConnectionNetStatus(nse:NetStatusEvent){
if(nse.info.code=="NetConnectionConnectSuccess")
{ shared = SharedObject.getRemote("thread", connection.uri, false);
shared.client = this;
shared.addEventListener(SyncEvent.SYNC, receiveVariable);
shared.connect(connection);

[Cristian Rusu]

Also is this really correct?

"rtmp:/Red5Trhread

I can see a typo there...?

@Cristian : it's correct, I make a typo when create project :D
@Andy: I'll try it, bro. thanks

[Frenda Rangga Aksara]

@andy: I have did what you have said. Move sharedObject definition at onConnectionNetStatus. But, it's still same problem. How about Sync.Event, is it true?
sorry, i don't have any idea about this problem.

[Frenda Rangga Aksara]

hmm, I can't solved it yet.

[Frenda Rangga Aksara]

Hi Cris and Andy. Finally I make it, the problem is at my client function when receiving sharedobject data. I make a typo, because the compiler didn't notice it.
Thanks to you all.

The method you tried to use is not for notifying shared object subscribers, it is a base Object method and must be used in a synchronized block. If you want to know more about it, read this post: http://www.java-samples.com/showtutorial.php?tutorialid=306

Hi, mondain. So, in your opinion. What must i do to notify  the change of shared object ?

[Cristian Rusu]

Nothing, it should update connected clients automatically
