Hi,
Thanks for your reply. Actually we are new to both LS & Java application. So, not able to get you. Are you asking us to check the "onLostUpdates" callback at client side coding?

In GWT, we are using the following methodology to receive the JSON message sent by LS server.

public native void publish() /*-{
$wnd.jsonUpdatedStaticJS = @com.chellasoft.http://www.client.ChellaSoft::jsonUp...lang/String;);
}-*/;

If you don't mind, Can we get the detailed information?

Note: In LS server side(Meta Data Adapter), we are able to print all the messages sent to client. but not at the client side.

Thanks,
Latha.P
