Running JAR file on Windows

Question

I have a JAR file named helloworld.jar. In order to run it, I\'m executing the following command in a command-line window:

Answer 1

In Windows XP ^* you need just 2 shell commands:

   C:\>ftype myjarfile="C:\JRE1.6\bin\javaw.exe" -jar "%1" %* 
   C:\>assoc .jar=myjarfile  

obviously using the correct path for the JRE and any name you want instead of myjarfile.

To just check the current settings:

   C:\>assoc .jar  
   C:\>ftype jarfile  

this time using the value returned by the first command, if any, instead of jarfile.

^* not tested with Windows 7
