So I've been having this problem for a while, and the problem is that when I run any .jar file by double-clicking it, I get an error saying "Unable to launch the application.", and this didn't happen before. I tried to delete and re-install both the JRE and JDK, but that didn't help either. I also tried resetting the Path variable, but that didn't work as well.


There's a "Details" button on the error window, and when I click it the exception is as follows:

1  
2  
3  
4  
5  
6  
7  
8  
9  
MissingFieldException[ The following required field is missing from the launch file: <jnlp>]

   at com.sun.javaws.Main.continueInSecureThread(Unknown Source)
   at com.sun.javaws.Main$1.run(Unknown Source)
   at java.lang.Thread.run(Unknown Source)


I'm also using JRE version 1.7.0_04-b20. Any ideas what the problem might be? Undecided

Looks like your file association got screwed up and and associated all jars with javaws instead of javaw.  If you're on windows, there's a clicky way to fix this: http://www.softpedia.com/progDownload/Jarfix-Download-79716.html
