Thread: Desktop Notifications using JEE

I got a requirement like to get Desktop Notifications using JEE ( In a web based application).

A web application is normally executed on a server machine and then the results (HTML plus other) are viewed/executed typically by a browser on the client machine.

Is that possible to show popup on desktop through the webapplications?

At server side, being on another machine, you can't do anything directly on the client machine. You send to a client typically a mix of HTML, CSS, Javascript code. And this is handled by a browser (again, typically).

I've researched for it and came to know about the JNLP (Java network layer protocal) file which is deployed into client system.
JNLP is displaying a desktop notification but I'm not sure how far this can be useful.

JNLP is a Java technology to launch a standard Java application (with some restrictions by default) on the client starting from a simple link/button on a web page.
So a Java application on a client can certainly do more respect to a browser. However, the standard Java SE framework has no direct specific API for "desktop notifications". Since Java 6 there is the System Tray API but it's another thing.
Obviously a Java desktop app can certainly open a custom popup window but this is not a "standard".

EDIT: effectively, the TrayIcon class, since Java 6, has a displayMessage method. I have never used it before but javadoc states: "Displays a popup message near the tray icon.". So this may be what you want.

At browser level, yes, there is something. Follow this search: https://www.google.it/?gfe_rd=cr&ei=...+notifications
