event bus bridge cannot ok on vert.x 1.3

[Yi Long]

Hi all
recently I just quickly implement the event bus bridge on Vert.x 1.3.
but client side always throw the "INVALID_STATE_ERR", in vertxbus.js,
when registerHandle or publish, it always check the state, if state !=
vertx.EventBus.OPEN will throw Error('INVALID_STATE_ERR') ,who can
help me on that?
thanks in advance

the code on server side:
HttpServer httpServer = vertx.createHttpServer();
httpServer.requestHandler(new Handler<HttpServerRequest>() {
public void handle(HttpServerRequest req) {
String file = req.path.equals("/") ? "index.html" : req.path;
req.response.sendFile(serverRoot + file);
}
});
SockJSServer sockJSServer = vertx.createSockJSServer(httpServer);
// Set security permission to let everything go through
JsonArray permitted = new JsonArray();
permitted.add(new JsonObject());

//bridge to eventbus and allow
sockJSServer.bridge(new JsonObject().putString("prefix", "/
eventbus"), permitted, permitted);

eb = vertx.eventBus();

myHandler = new Handler<Message<JsonObject>>(){

public void handle(Message<JsonObject> event) {
eb.publish(_Complete_Update_Topo_Event, new
JsonObject().putString("aaa","bbbb"));
}

};
//register event that ask for update current status of Topology
eb.registerHandler(_Ask_Update_Topo_Event, myHandler);
httpServer.listen(8080);

client side:
<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script src="http://cdn.sockjs.org/sockjs-0.3.4.min.js"></script>
<script src="js/vertxbus.js"></script>
<script src="js/json2.js"></script>
<script>
var eb = null;

function publish(msg) {
if (eb) {
var json = {
text : msg
};
eb.publish('asking', json);
console.log(' ---- publish event ----');
}
}

function subscribe() {
if (eb) {
eb.registerHandler('completing', function(msg, replyTo) {
alert(msg);
});

}
}

function openConn() {
if (!eb) {
eb = new vertx.EventBus("http://localhost:8080/eventbus");
//eb.sockJSConn.onopen();
eb.onopen = function() {

};

eb.onclose = function() {

eb = null;
};
}

}
function closeConn() {
if (eb) {
eb.close();
}
}
$(function() {

openConn();
subscribe();
publish('hello');
});
</script>

That error is given when the socket is not open.

Without really looking at the code, you'll have to make sure that you are actually able to establish an open sockJS connection to your server.

don't call subscribe() or publish() until eb.onopen has been called

I have tried to call eb.onopen but the state is still
"INVALID_STATE_ERR", how could I make the state open? thanks

no, you need to move subscribe and publish into the onopen function. it is called when the connection is successful,  you don't call it explicitly yourself

hope this makes sense

thanks all of your replying , I found the problem is that I have to
bind publish or subscribe to dom event, that means after page load
then the sockjs will connect to server side.
after I bind publish to button click, then everything is fine.
thanks

I meant that you could change openConn to:

    function openConn() {
        if (!eb) {
            eb = new vertx.EventBus("http://localhost:8080/eventbus");

            eb.onopen = function() {
                subscribe();
                publish('hello');
            };

            eb.onclose = function() {
                eb = null;
            };
        }
    }

And you last function to just:

    $(function() {
        openConn();
    });

Then subscribe won't be called till the connection is open...

Glad you got it working though.

The other replies are correct, but also please look at the working eventbusbridge example in the distribution which shows how to do this.
