Solve the problem that jar files cannot be double-clicked in Windows 7.

Problem: you cannot double-click to run the JAR file in Windows 7. That is to say, there is no response after double-click. In addition, WinRAR and 360 are compressed under Windows 7. You can view the contents of the JAR file. However, you can run it directly in the command line !!

 

Solution:

1. Select the default program: Right-click the jar package and choose "open method"> "default program"> "View". Select javaw.exe in the binfile under "jre" (for example, javaw.exe in C: \ Program Files \ Java \ jdk1.7.0 _ 04 \ bin ).
2. Edit the Registry: hkey_classes_root \ applications \ javaw.exe \ shell \ open \ command, and change the data value to "C: \ Program Files \ Java \ jdk1.7.0 _ 04 \ bin \ javaw.exe "-jar" % 1 "(that is, you only need to add-jar to the original value ).

In this way, double-click the JAR file to run it directly.
