I am seeing a problem with Web App Start running the same old jnlp.

I have been running on Mac, Darwin Kernel Version 10.8.0, forever. All of a sudden, I am not able to run the app from web start.

java -version
java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-10M3909)
Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

from the console, I run

javaws ./my.jnlp 
Java Web Start splash screen process exiting .....
    Bad installation. No JRE found in configuration file

the jnlp file contains:

<security>
    <all-permissions/>
</security>
<resources>
<j2se version="1.4+" initial-heap-size="128m" max-heap-size="256m" />

Not sure what is going on? Any ideas anyone?

Should your problem reappear, or should somebody else run into the same problem... Oracle's Mac Java FAQ states: "Apple disables the Java plug-in and Webstart applications when the Java update is done using Software Update." You can download Java 7 for the Mac from Oracle and use it for Webstart. See https://www.java.com/en/download/mac_download.jsp

Apple has been intermittently issuing software updates which disable Java applets and Webstart for awhile, so the problem may indeed resurface later.

I ran the software update for Java on my Mac and the problem disappeared. It came as a mystery, only fair for it to go away in mystery also.
