JAVA_HOME set to 32bit jdk but java -version shows 64bit

The environment user variable for JAVA_HOME is set to a 32 bit jdk on my machine at-"C:\Program Files (x86)\Java\jdk1.6.0_31" and the PATH includes JAVA_HOME. But when i check java -version from command prompt it shows 64bit version is running.

java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b05)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode)

I need to run 32bit version, is there something i need to change?

A suggestion how to set the OS environment variables for development tools.

Consider having installed Java, Ant, and Maven. Consider having the following directory structure for these installations:

C:\
 |
 |--- Programs/
 |       |--- Java/
 |       |      |--- jdk7/
 |       |      |     |--- bin/
 |       |      |     |--- <other files and directories>
 |
 |--- Tools/
 |       |--- apache-ant/
 |       |        |--- bin/
 |       |        |--- <other files and directories>
 |       |--- apache-maven/
 |       |        |--- bin/
 |       |        |--- <other files and directories>

Then you should have the following three HOME variables:

JAVA_HOME = C:\Programs\Java\jdk7
ANT_HOME = C:\Tools\apache-ant
M2_HOME = C:\Tools\apache-maven

Your PATH variable then should look like this:

PATH = ...;%JAVA_HOME%\bin;%ANT_HOME%\bin;%M2_HOME%\bin;...

From now on you only need to change the HOME variables when versions change. And your OS always finds the tool you want to start.

You need to change your PATH variable. JAVA_HOME is a variable normally used by java programms. The PATH variable is used for all kind of executable programms (like java vm).
