Java web start does not work

Question

Java web start does not work

I have followed the instructions in this article, including the last step about web start, but it still does not work, neither applets or web start. When I try to launch a JWS application by double clicking it I get the dreaded warning dialog:

---------

To open this Web Start application, you need to download the Java Runtime Environment.

Click “More Info…” to visit the website for the Java Runtime Environment.

---------

I do have a JRE installed, 1.6, since I for compatibility reasons can't upgrade.

Trying to launch a web start application from the commandline looks like this:

$ javaws /tmp/airview.jnlp

Java Web Start splash screen process exiting ...

Can not find message file: No such file or directory

Regular Java-programs work fine.

$ java -version

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)

Java-OTHER, Mac OS X (10.7.5)

Read this thread https://discussions.apple.com/thread/4789691?tstart=0

This fixed the issue for me:

sudo /usr/libexec/PlistBuddy -c "Delete :JavaWebComponentVersionMinimum" /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta. plist

In the comments to the linked article someone suggests to comment out the node in stead of deleting it. Probably safer (it's explained further down how to do that). Anyway I already spent to much time on this nonsense, deleted it and it worked, so I'm happy.

Hmm I jumped the gun a little to quick there, now I can launch jnlp files from the command line but I still cannot double click them. Do you know why?
