I want to package some classes into one file.
So I try to run command:
C:\Program Files\Java\jdk1.7.0_10\bin\jar.exe
But the error is weird. C:\Program Files\Java\jdk1.7.0_10\bin\jar.exe is not a valid Win32 application.
What should I do now? Do I need to install any other tool?
I reinstall the 64bit version jdk, and it works
