Have multiple Macs running 10.5.7 w/latest software update. Install mac for pc. Each trying to use the same web application. Web app downloads a.jnlp file. For most Macs, it launches Java and life is good. On a lone Mac (so far), the.jnlp file downloads, but is opened by TextEdit. Check File Info, and it's associated with TextEdit, so there's the culprit. On the working Macs, the file is associated with Java Web Start.app. Jun 3, 2016 - Discover how to use the JavaScript scripting language on your Mac. Learn how to code in Java on a Mac. Safari is fine as a web browser, but we don't advise creating code in TextEdit because it doesn't save as text files. So, I figured I'd change the association on the Mac that's broken, but I can't find Java Web Start.app. It doesn't show up in Spotlight, so I use the locate command in Terminal and find it listed as being found in /Applications/Java. This folder does not exist on any of the Macs in this scenario. Where is it?! How do I fix the association for.jnlp files to be Java Web Start.app? I have the same problem. After running the latest Java update, Java Web Start is gone. I have Xcode installed on my machine, but still don't have Java Web Start anywhere on my drive. I attempted to restore it to /Applications/Utilities/Java using Time Machine, but when I launched it, it merely crashed. I understand that part of the Java update was to patch a vulnerability that could be exploited through Java applications launched from the web, but I was under the impression that there was a fix that didn't simply involve disabling Java Web Start. Is there a new version of Java Web Start out there that doesn't crash with the new Java update? Alternately, is there a way to run a jnlp file without a working version of Java Web Start? I have a program that I absolutely need to have running in the next 30 minutes -- which doesn't give me enough time to roll back the whole update. Is it too much to expect Apple to fix what they broke with this update? In my case, the problem popped up with a jnlp file I've been running every business day for the last 3 years or so. Apple has broken it with Java updates before, but never like this. Using the version in the /System/Library/CoreServices got it to launch, but it hung right away, rendering it useless. Like I said, I understand that the security issues with web launched apps needed to be addressed, but disabling web launched apps entirely seems like overkill when Apple has trailed substantially behind Sun in patching a well known security flaw. ![]() Anyone who runs jnlp apps from an unknown source gets what they deserve, but please don't punish those of us who know the source of our apps. I've got the same problem. My JNLP files open in TextEdit. Free video player for mac that can play all formats. Java Web Start has gone missing from the Applications -> Utilities folder after I upgraded to the latest Java. In fact, the entire folder is gone. All that remains is the Java Preferences application. When I go to associate the JNLP file with javaws (System/Library/Frameworks/JavaVM.framework/Versions/A/Resources/Deploy.bundle/ Contents/MacOS) it is not seen as an application. So where has this function gone? I've looked through Safari 4.01, but have found nothing. And it doesn't appear to have been incorporated into the Java Preferences app.
