与Windows的“路径变量”中Java的“ bin”目录混淆-如何解决此问题？

Question

So on my server running Windows Server 2008 x64 R2 I installed the Java JDK 7 Update 5. I added "C:\\Program Files\\Java\\jdk1.7.0_05\\bin" to the System "Path" variable.

Now in console, certain Java executables like java.exe work, but others like javac.exe only work whenever I'm actually in that "bin" directory.

Does anyone have a clue what I did wrong and how I can fix this?

EDIT: Whenever I enter 'javac' it returns:

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

When I type 'PATH', I get:

PATH=C:\PROGRA~2\PARALL~1\Plesk\ADDITI~1\Perl\site\bin;C:\PROGRA~2\PARALL~1\Ples
k\ADDITI~1\Perl\bin;C:\Program Files (x86)\Parallels\Plesk\Mail Servers\Mail Ena

还创建带有Java路径的环境变量JAVA_HOME

Answer 2

Try this,

For eg:

My JDK is located in my C:\\Program Files\\Java

So you must do as following:

Copy C:\\Program Files\\Java\\jdk1.7.0\\bin , then goto your "Path" variable and set this...

And yes.. open you command prompt and give the following command..

gpupdate /force
