How do I get a JNLP file to auto-launch on click? (as opposed to clicking save or open when clicked) Is this some type of MIME association that the browser must first recognize?
回答1:
There is a server configuration file that specifies MIME or content type by file extension. For JNLP, it should be application/x-java-jnlp-file.

I think the other answer is outdated as of today.
Try changing your link from http:// or https:// to jnlp:// or jnlps://.
So your url would look something like this: jnlp://your.server/path/yourjnlp.jnlp
Caveat: For me, typing this in the Chrome URL doesn't work. It needs to actually be a link inside the page that gets clicked. There may also be a Windows requirement but I haven't confirmed that.
