java web start launcher has stopped working

If entries shown look like you see it in this screen shot then this version of Java is disabled on your computer ( and by the way you can use these Control Panel functions to decide which version of Java you like to enable / disable on your computer ). This can be checked through Control Panel, clicking on the appropriate Java icon, then on the “Java” tab and “View” button.

I picked a javaws.exe file I found on my computer, and key here is to put a “%1” behind the program name, something apparently not possible when trying to do the same thing from Internet Explorer ( Version 8 ).Īfter doing this Java Web Start worked again from Internet Explorer, but I bumped into another problem:Īnother hurdle is to make sure that the Java Runtime of the version of javaws.exe you picked is enabled on the Windows System. This dialog doesn’t work very user friendly as well: after having specified an action this one does not show up in the list of actions. Now the Advanced button became available letting me assign an action (“Open”) and a program to files of type JNLP. After this I clicked on New and specified “JNLP” as a extension to create a new file type entry. It started with a brave step: clicking on the Restore button for JNLP files, then deleting this entry entirely. Nevertheless, the behavior of the dialog to assign a program was as weird as when invoked from the IE browser. This article was very helpful to explain an alternate way: changing the assigned programs for JNLP files in Windows Explorer Folder Options –> File Types. Instead the browser showed me a prompt like this one:Ĭlicking on Browse… and navigating to the proper javaws.exe file ( the Java Web Start Launcher ) did not solve the problem, and this entire mechanism does not seem to work properly after selecting the javaws.exe file it did not show up properly in the list of Recommended or Other programs and I could not fix my problem. Launching it did work with Firefox, but stopped working with Internet Explorer. Somehow I ended up with an Internet Explorer not allowing me anymore to launch a java web application.
