Installing the Java Plug-in. The Laj and Maj applets are written for Java 1.2 (a.k.a. J2SE 1.2), and theoretically any web browser that fully supports this (or any higher version) should work. However, for best compatibility we recommend that you download and install the official Java Plug-in software from Sun Microsystems. This plug-in.

I am running a jnlp in OSX 10.8.2 with jre the jre version 1.7.0_11 and jnlp tag is set to run in 1.6 as:

or

However, when the jnlp runs shows the following in the console:Java Web Start 10.11.2.21Using JRE version 1.7.0_11-b21 Java HotSpot(TM) 64-Bit Server

When I run the same jnlp file in windows using jre 1.7 works fine, it loads with jre 1.7 and then download jre 1.6 and run on it.

Any ideas?

Now, they told me they need java 1.7 as default.

So, I found that installing JDK 1.7 instead of JRE, it was fixed. I can have both versions and my jnlp is using jre 1.6 to run.

And then I had to run the follwoing commands from http://support.apple.com/kb/HT5559:

sudo mkdir -p /Library/Internet Plug-Ins/disabled

sudo mv /Library/Internet Plug-Ins/JavaAppletPlugin.plugin /Library/Internet Plug-Ins/disabled

sudo ln -sf /System/Library/Java/Support/Deploy.bundle/Contents/Resources/JavaPlugin2_NPAPI.plugin /Library/Internet Plug-Ins/JavaAppletPlugin.plugin

sudo ln -sf /System/Library/Frameworks/JavaVM.framework/Commands/javaws /usr/bin/javaws

After run this, the java applet plug-in starts to work in Chrome and I can handle all versions of Java from Application/Utilities/JavaPreferences

The root cause:

1. jnlp is set to only use java 1.6 otherwise download it from auto download site and installed automatically

2. All java versions for mac but 1.7 were developed by Apple so they do not have autodownload url

3. After 1.7 oracle is developing java for macs

4. When I review the java preferences only found java 1.7

5. Jnlp looks for java 1.6 and is unable to find it and try to autodownload and is unable to do it either, so the only option it has is run on java 1.7

To solve this we uninstall java 1.7 and then we use the following instructions to make 1.6 java default:http://support.apple.com/kb/dl1573
