Running through command prompt( Possibly Path error?)

Question

I have a problem when compiling my code from Notepad++ when i compile example( javac StudentApp.java). It does not compile but instead i get this error code - "is not recognised as an internal or external command operable program or batch file". I use Windows 8 - well 8.1 now. This is my path:

C:\Program Files (x86)\AMD APP\bin\x86_64;C:\Program Files (x86)\AMD APP\bin\x86;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Windows Live\Shared;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;append

If anyone could help I would greatly appreciate it. Thanks.

Answer 1

First be sure you have installed JDK , but not the JRE (jre comes without the javac).

Here's how you can the JAVA_HOME\bin to your path (in case you have installed JDK):

for /f  "delims=" %j in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit\1.6" /v JavaHome') do @set jreg=%j
set jreg=%jreg:    JavaHome    REG_SZ    =%
setx PATH "%jreg%\bin";%PATH%

Thanks everyone i got my solution i left out the bin directory which was " C:\Program Files (x86)\Java\jdk1.7.0_45\bin;" at the start of my path. Hope this helps anyone else with the same problem.
