Thread: Jar command problems

Hi,

When I try to run the simple 'jar' command on the Windows terminal I get the following error:

'jar' is not recognized as an internal or external command, operable program or batch file.

I have the latest JDK version installed, any ideas?

Thanks

Ok I see. I'm not sure where the jar command is located in Windows, it comes with the JDK package, right?

I'm using a tutorial to create a jar file with a bundle of java classes, but I came across this jar command problem, so therefore I have no idea about this jar command in the first place

Thanks

Yea I came across a Java folder in Program Files, and in the Java folder there is another folder called jre6. I did a search on jar, which resulted files that ended with the .jar extension. But there was no jar.exe command file? What is the standard representation of the jar command (name and extension type of file)?

Thanks

I cant seem to find the any JDK folders? I only have the jdk6***-64.exe file which I installed before, but no folders?

Thanks

Thanks for your time. Although I do have the JDK installed as I've been writing java programs with this computer.

Thanks

I can't even find the javac command anywhere on my computer. Is there a link to download the jar command? I've searched, but no positive sites.

Thanks

Yes i compile them on this computer. I use Jgrasp to compile them?

Thanks

I don't think so. I just click the 'Run' button on the Jgrasp IDE and it then returns the result on the JGrasp console. I don't use the command terminal for compilation.

Thanks

the problem is likely that you have set the path of jdk in the environment variable. i believe you are using window 7. if this is so, follow this simple steps if you have successfully installed your jdk
firstly, you need to know where your jdk is located on your system. you can find this by tracing it doing
go to your local disk, then to program files, then to java, then to jdk, then to bin.
you copy the path to be like this, c:\program files\java\jdk1.7.0_09\bin
note: the version of the jdk may vary.
secondly, go system properties, then to advanced system settings, then to environment variable, then under system variable locate path and click on "edit" just tab the front arrow key to make sure you didnt clear the highlighted directory
now, append a semicolon followed by the copied path in step one.
then click ok.

Thanks for your reply.

Yes that worked, thanks alot. See computer has two 'Program Files' folders (Program Files and Program Files (x86)) for some odd reason, and I was looking in the (x86) folder, but was located in the original folder. Thanks again for your help
