I have sun-java6-plugin installed on my 10.10 AMD64, and I tested on the Java website that it works with applets.

However it doesn't work with web start - I have to download the jnlp file and double click to open.

Is there a way to integrate web start to my browsers?

It's a protocol handler thing. It works for me, but the jnlp handler might be disabled as a security risk(it can be). – RobotHumans Dec 16 '10 at 13:02

I have both Firefox and Chrome installed. Both don't work for jnlp – segfault Dec 19 '10 at 18:33

In firefox go,

Edit -> Prefferences -> Applications -> JNLP File 
Choose SunJDK Java 6 Web Start

I had a problem like this and I resolved it by intalling icedtea-6-plugin or icedtea-7-plugin. It depends on the case.

To integrate web start to my browsers follow the steps.

If you just run the applet code inside html tags it doesn't work. Run them inside script(javascript) tags.

  1. get the jars and class out of jnlp file and put them into applet code.
  2. then make that applet runs as java script from your html code.
