How to run.jar file by double click on Windows 7(64) (10) Installing the newest JRE fixed this for me. (Even though I had a JDK and JRE(s) installed before.) Running a.jar file in a command line works fine, but i am not able to run any.jar file by double clicking on my Windows 7 (64).

What is a JAD file?

JAD stands for Java Application Descriptor file. This particular file extension was developed by Sun Microsystems. Files with the .jad extension are descriptor files that are commonly used to describe the contents of a MIDlet.

MIDlet files are created for the Java ME virtual machine. MIDlets are commonly used to package applications and games that have been created for cell phones and other mobile devices. For the MIDlet application to run properly, it must have both a .jar and .jad file associated with it. The .jar file contains the actual application data and the .jad file contains the technical information needed to operate the MIDlet program.
