jnlp file is prompting mac to download JRE, but its already installed (Java 1.6.0_37) Mac OSX 10.7.5

Question

I don't even really know what to post in here except for the fact that the terminal on the computer says:

java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

but for some reason when i run the JNLP file a prompt pops up saying that to open this web start application I need to download the Java Runtime Environment. Which I already did. It originally installed Java 7, and after doing some research I discovered that this jnlp file won't open with Java 7 installed. So I went back and removed Java 7, and now this is happening.

If I open the Java Preferences window, I can see that Java SE 6 is indeed installed. I just have no idea what to do.

EDIT:

The terminal says

No Java runtime present, requesting install. Unable to locate a Java Runtime to invoke.

when I put in

javaws /(path).jnlp

Also I ran janela, and got this report:

Note that a java/j2se version of 'n.n*' will limit the app. to that  specific Java runtime, and no later.  It is often better to specify  version as 'n.n+'.

I'm sorry i know its a lot, but I don't even know what is important and what isn't. Hope this helps.

Answer 1

As discussed here , Apple disabled this and earlier versions of Java pending a security update. Version 1.6.0_39 is now extant via software update, as described here and here .

Answer 2

I had the same problem and this solution here worked just fine:

Answer 3

If you installed Oracle Java 7, you can run jnlp files with:

'/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/javaws' file.jnlp

If you would want, you can also replace /usr/bin/javaws file with a symlink to /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/javaws .
