"java -version" not working in command prompt

Issue

I downloaded this Java JDK and installed it.

But when I go to the command prompt to check the version, it says it's not recognized.

Is anyone else experiencing this issue with the latest Java?

I might not have installed the right version. I need the java that works with grails

C:\>java
'java' is not recognized as an internal or external command,
operable program or batch file.

C:\>java -version
'java' is not recognized as an internal or external command,
operable program or batch file.

C:\>

when i do a search on my computer for java, it does not find anything

Solution

Windows 2k8 R2 server- For both java [-option] or %JAVA_HOME% to work in the command line you need the following:

In Control Panel->System and Security->System->Advanced system setting->Advanced->Environment Variables->System Variables

Edit the Path variable and add a ";" after the last value and add the the path to the Java bin directory: e.g.- C:\Progra~2\Java\jre6\bin\

Add the JAVA_HOME Variable with the value set to the path for the java executable: e.g.- C:\Progra~2\Java\jre6\bin\java.exe
