Hi, May I know what port is used by Java Web Start?

Hi, We are using WebStart JNLP file to create a shortcut on our users` desktop. The problem is that we would like the code in our jar file to be launched only when the user press the desktop shortcut.

Hi, I am looking for a code signing certificate that will be accepted by Java Webstart. It is for the Arianne Project (a ten year old open source project hosted on Sourceforge). Unfortunately being "just" a spare-time open source project means we cannot proof our identity by posting extracts from the register of companies. Another issu...

My Java Webstart application download some large resource files.

I'm developing a game that I will distribute using Java Web Start / JNLP. Currently the fully packaged .jar is around 11mb, which is not too bad, but I'd still like to get the application responsive as quickly as possible, i.e. before everything is downloaded - in particular I'd like a splash screen during loading, then allow other reso...

Is there any way to force browser to execute jnlp right after the download completes, or event better, to make the whole process transparent, so user just confirms that he wants to launch the application? Thanks. ...
All my application I make with NetBeans as a Java Web Start applications behave quite strangely. When I run them as a normal application, everything works.
