Passing values between different applications in ExtJS 4.2

Question

Currently I am working on an project where ExtJS 4.2 is used for the UI. So suppose I have a standalone project X (a .war application) deployed in server(tomcat) . So if I am creating another standalone project Y(another .war application) and deploy it to server(different tomcat) , is there any way to pass values from one view of UI of Project X to one view of UI of Project Y and vice versa.

Currently the projects works on mvc

Thanks

You can not pass messages (values) on client side(UI). Moreover, even somehow you can manage to do it, it is very bad practice.

1) You can use HTTP / JSON service calls between applications and using web sockets/ polling get message with other application's UI.

ie. X app calls Y apps web service and Y pushes notification to UI with websockets/ polling.

2) Another way in UI Y calls X web service (HTTP/JSON or SOAP ) and gets messages.
