I have created a java app and I would like to be able to execute actions in this app by calling some custom urls (ex: myapp://do_this)

I have already searched for this, and I have found some information about handling such urls in java (URLStreamHandler).

The only part I’m missing, is how to tell the OS to redirect the “myapp://” protocol to my application.

More and more apps are defining their own protocol and I was wondering whether it was possible to create such kind of things in Java.

Thanks

    The protocol in URLStreamHandler will be used inside of the jvm. Typical usage is something like res://… for resources. The OS and the browsers have their own sets of protocols (ftp, mailto).

    You could probably extend Firefox with a plugin to handle your protocol.

    But then you have to send that to your app, running as a small “web” server.

    Forget for a moment URLStreamHandler.

    Embed the Jetty web server in your app, say on port 8765, and write a servlet to handle your URLs. Then you can in your browser type “http://localhost:8765/do_this”. Should suffice.
