I have an iMac running 10.6.8. I'm having a problem with .jnlp files. I've downloaded two, cgoban.jnlp and gopanda.jnlp. When I double-click the file, nothing happens. If I Control-click and select Open With Java Web Start, same. Nothing happens. Software Update says my Java is up to date. Any ideas?

iMac, Mac OS X (10.6.8), Java Web Start.app v.13.8.5

    Java 7 updated  for 10.7-10.8

     

    Released Feb 1, 2013,  fixes 50+ security flaws

    Download and install

     
    https://www.java.com/en/download/faq/java_mac.xml
     

     

    For Java versions 6 and below OS X 10.5-10.6 machines


    Apple supplies their own version of Java. For Mac OS X 10.6 and below, use the Software Update feature available under the Apple menu to check that you have the most up-to-date version of Java 6 for your Mac.

    Java SE 6 End of Public Updates
     
    After February 2013, Oracle will no longer post updates of Java SE 6 to its public download sites. We highly recommend downloading and installing Java 7.

     

     

    If your considering upgrading OS X from 10.6.8 to 10.8 via AppStore to run Java 7

     

    Be forewarned no PowerPC based programs or driver software will run any longer.

     

    Check here BEFORE you upgrade OS X!

    Alternatives if you must run Java 7

     

    If Apple disabled Java 6 in 10.6, and you can't upgrade OS X to 10.8, then your pretty much done with Java in OS X because Oracle won't issue updates for Java 6 anymore.
     
    However you can install Windows 7 and continue to use Java 7+ there until support for Windows 7 ends in 2020.


    Windows in BootCamp or Virtual Machine?

     

    If your on 10.6, I very highly recommend the free Virtualbox for the virtual machine software as it gets updates, VMFusion and Parallels have moved on with only 10.7+

    Check Software Update...

    APPLE-SA-2013-02-01-1 Java for Mac OS X v10.6 Update 12

     

    Java for Mac OS X v10.6 Update 12 is now available and addresses the

    following:

     

    Java

    Available for:  Mac OS X v10.6.8, Mac OS X Server v10.6.8

    Impact:  Multiple vulnerabilities in Java 1.6.0_37

    Description:  Multiple vulnerabilities exist in Java 1.6.0_37, the most serious of which may allow an untrusted Java applet to execute arbitrary code outside the Java sandbox. Visiting a web page containing a maliciously crafted untrusted Java applet may lead to arbitrary code execution with the privileges of the current user.

    These issues are addressed by updating to Java version 1.6.0_39.

    Further information is available via the Java website at http://www.oracle.com/technetwork/java/javase/releasenotes-136954.html

    That's very old, just like this thread, and it won't work any more as Java has been upgraded twice since then.

    Java stopped working for me again recently (after I most recently ran Software Update) and I had to reapply this exact fix; commenting out the keys, even though I've done it in the past.  And this thread isn't that old, only about a month.

    Which is an extremely dangerous approach to the problem, especially when an update to Java has been posted which patches the vulnerability. Taking your approach only allows you to be one of the first persons to discover a Zero-Day exploit. Apple would not have disabled it if it had not been in your best interest.

    And this thread isn't that old, only about a month.

    And as I said before, there have been two updates since this thread began. And just so you know, there have been something like five to eight new vulnerabilities uncovered and reported to Oracle since Monday.

     

    Check this site routinely to see how long it's been since the last discovery http://java-0day.com/.

     

    You want to live on the edge? Be my guest.

    A simple, "that will allow .jnlps to run, but it's dangerous, and shouldn't be necessary if you keep your Java up to date," would probably have been clearer and not sounded belligerent.

    Sorry, but I have some very strong feelings about this right now. From everything that I'm hearing from my contacts in the Java world, I am convinced that there will be no more Java use on the internet very soon, so the sooner we all cut the cord and push sites to abandon this broken system, the better off we will all be.

     

    I feel very sorry for those whose livelyhood depends today on using internet Java from their desktops. But I'm no longer going to waste any more of my time helping those who's games no longer work.

    One small additional remark. It is a mistake to think that Java is only used for playing games. Many companies in the financial industry use Java as well. My company has an erp application with about 1000 Java programs. It is very unlikely to think that because the Apple community does not like Java anymore, my company will decide to rewrite all these programs. It is more likely that my company will drop the support for Mac OSX and just continues to support Windows, Linux and other operating systems with Java. But when Apple wants to expand more and more into the business environments, Java support has not only to be continued, but also to be competitive with the other platforms. Currently it is not. Apple has made using Java for the average non-technical user far to complicated!!
