Where The Heck Is Java Web Start?

So you have a from-the-browser Java application that requires Java Web Start to load on your beautiful Mac, and that Java application is named something crazy like:
viewer.jnlp(192.168.1.123@0@idrac-BR2XXXX1,+PowerEdge+R710,+User_joeblow@3313732211320)

What do you do? It doesn’t open automatically, and when you double click the filename it just asks you what application you want to use to open the file.

Well I will tell you what you do!

  1. On the “Launch Application” dialog that opens when you double click the filename, click “Choose…” beside “Choose an Application”.
  2. Navigate to Macintosh HD > System > Library > CoreServices.
    /System/Library/CoreServices/Java Web Start.app
  3. Choose “Java Web Start” and click Open.

There you go. A post like this would have saved me 15 minutes anyways, hope it helps someone else.
