Javac is not found

Question

I'm running Windows 8 and I can not get javac to work.

I have set my PATH in environmental variables to

C:\Program Files (x86)\Java\jdk1.7.0_17\bin

I have tried both with and without ';' but to no avail.

I recently had this issue on my desktop and adding ; worked but it's not in this case.

I have made sure that javac does exist in the bin too.

Any suggestions on fixes would be greatly appreciated.

EDITS echo %PATH% gives:

C:\Users\Arktri\Desktop>echo %PATH%

C:\Program Files (x86)\Intel\iCLS Client\;
C:\Program Files\Intel\iCLS Client\;
C:\Windows\system32;C:\Windows;
C:\Windows\System32\Wbem;
C:\Windows\System32\WindowsPowerShell\v1.0\;
C:\Program Files (x86)\Intel\OpenCL SDK\2.0\bin\x86;
C:\Program Files (x86)\Intel\OpenCL SDK\2.0\bin\x64;
C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;
C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;
C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;
C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;;
C:\Program Files (x86)\Java\jre7\bin

And the exact error is: 'javac' is not recognized as an internal or external command, operable program or batch file.

Solution 1

As far as I can see you have the JRE in your PATH, but not the JDK.

From a command prompt try this:

set PATH=%PATH%;C:\Program Files (x86)\Java\jdk1.7.0_17\bin

Then try javac again - if this works you'll need to permanently modify your environment variables to have PATH include the JDK too.

Solution 2

1. Go to my computer;
2. Right click properties;
3. Go to advanced system settings;
4. Go to environment variables;
5. In user variables for user click on new(top new button, not on system variables);
6. Set variable name as: Path
7. Set the value of that variable to: C:\Program Files\Java\jdk1.7.0_76\bin
8. Click ok;
9. Click ok;
10. Click ok.

Now you're set. Type javac in cmd. All javac options will be displayed.

EDIT: As @MediaMaker pointed out, after completing the above steps, you need to open a new command prompt for it to work.

Solution 3

Easiest way: search for javac.exe in windows search bar. Then copy and paste the entire folder name and add it into the environmental variables path in advanced system settings.

Solution 4

I'm searched many answers that suggest me to type in cmd:

set path = "%path%;c:program files\java\jdk1.7.0\bin"

but this is WRONG!

the right solution is that you leave "set" and just type

path = %path%;c:program files\java\jdk1.7.0\bin

P/s: of course you have to replace "jdk1.7.0" folder by your current java version folder. This works well on win 7 32bit, but I think it also works on win 8 - try it!

can you start a shell, type echo %PATH% and post results?

What is the error that you see? Saying "I can not get [it] to work" doesn't tell us anything about the problem.

[Eric Leschinski]

The double semicolons might be a problem.

[FazoM]

Do you have an extra space in you path? I can see: Pr ogram Files there...

Could you include here the information how to do it permanently?

[Sean Landsman]

I should have when I first posted this answer, but I suggest taking a look at @user4611364 answer below. Doing it that way will set it permanently (assuming you're using windows)

note that if you already have a cmd open and try to use that, it won't seem to work. You'll need to open a fresh cmd.
