Reload of the page causes multiple request

[Veeramani]

When the JSP page which is subscribed to a channel gets reloaded,
there are multiple requests fired hitting the server as if load
testing is happening.

The following is the code that is used in the jsp page.

dojo.require("dojo.io.cometd");
dojo.io.cometd.init({}, "/bayeux/cometd");
dojo.io.cometd.subscribe("/callback/channel/jsp", null, "onUpdate");

When the F5 key (refresh) is pressed, the request is happening few
thousand times before it goes for long pooling.

Anyone faced this issue please?

Thanks

That's not the right require() for cometd.
No idea what you're requiring here, but for CometD is
require("dojox/cometd") (Dojo 1.7+).

URL must be absolute.

> dojo.io.cometd.subscribe("/callback/channel/jsp", null, "onUpdate");

Doing a subscribe just after init() is wrong.

Please read the documentation about the API usage at
http://docs.cometd.org/reference/#javascript

Hi,

I am following the example from the following link:

http://docs.oracle.com/cd/E12840_01/wls/docs103/webapp/pubsub.html#wp158992
Section: Updating a Browser Client to Communicate with the Pub-Sub
Server

The question is when the page is reloaded, hundreds of requests are
fired. What can go wrong here please?

Thanks
Veera

No idea, you are using a different library, not CometD.
You should ask to Oracle.

If, instead, you decide to use CometD, then we may be able to help you.
