Cannot use jar command on windows

The jar command is not working on my box. I have downloaded the jdk, and set the envar "Path" to include the path to the jdk \bin directory. However, I still get that annoying message, "'jar' is开发者_JS百科 not recognized as an internal or external command, operable program or batch file." Does anyone have any suggestions to solve this problem?

I think from the error message that you're using Windows?

If so, did you try it in a command prompt that you opened after changing your path using the GUI? And did you double check for typos in the path you added?

You can always try running "echo %PATH%" to check your path, and ensure your change is both showing up and error free

Can you paste the result of env command ? Or please launch new command prompt, then please try again if you think you configuration is Ok.
