How to locate my java jdk folder and edit the path variable - integration maven

Question

i have Windows Vista and i'm trying to install maven and test it. But i realised that i have a problem with JAVA and i have to solve first.

I do Start->Run->cmd

and i type in the command line,

C:\>mvn clean

i get the following error

ERROR: JAVA_HOME not found in your environment. Please set the JAVA_HOME variable in your environment to match the location of your Java installation

So i say: Let's set the PATH for Java and i did:

Start->Control Panel->System->Advanced System Settings->Environment Variable->System Variables

Edit the PATH variable

C:\Program Files\Java\jdk1.6.0_32;C:\apache-maven-3.0.4\bin;

But then i get the same error when i do:

C:\>mvn clean

Then i typed in the cmd prompt:

  C:\>java -version
  java version "1.7.0_07"
  Java(TM) SE Runtime Environment (build 1.7.0_07-b11)

and i realise that the Java version that is running is not located under the "C:\Program Files\Java" directory

The only JDKs i have are: jdk1.6.0_29 jdk1.6.0_32

Then i did Run->cmd

C:\>where java
C:\Windows\System32\java.exe

(Recently i downloaded IDE Eclipse and IDE IntelliJ and i don't know if these apps come with the JDK).

Where can i find my JDK installation in Windows and set the path in environmental variables?

Answer 1

Go to

 Start->Control Panel->System->Advanced System Settings->Environment Variable->user variables

Click on new button

give the

     variable name : JAVA_HOME
     variable value: C:\Program Files\Java\jdk1.6.0_32

in that way you setup your java home and try

Also make sure to take new command prompt after you did any changes in environment variables
