matlab java builder not working properly, i.e deploytool doesn't works properly, build fails

well i'm using matlab deploytool to convert my matlab code into java. em following this tutorial, but building fails. this is what i get..

'javac' is not recognized as an internal or external command, operable program or batch file. Error: An error occurred while shelling out to javac (error code = 1). Unable to build executable.

this is the error em also getting, plz @madhura suresh, do help me :) or someone else do help me, as its very important for me.. by executing this command:

version -java

Java 1.6.0_12-b04 with Sun Microsystems Inc. Java HotSpot™ Client VM mixed mode

i've tried very hard to fing this compiler but couldn't find it, is there any other way to counter this problem? i.e i should be able to generate java code of my matlab algorithm.

i've followed this question and has tried the things mentioned in it, but now em not able to find this compiler of java so that i should install it. em using matlab r2009a.

Do you have the JDK installed on your machine? It is possible that you only have the JRE on your machine. Also add the path to JDK/bin and JDK to your Windows path, so that Builder JA can see the Java compiler (javac).

Have you set the JAVA_HOME and MATLAB_JAVA to point to the JDK accordig to teh builder JA doc?

well i've jdk 1.7 installed on my machine, but how to set the JAVA_HOME and MATLAB_JAVA to point to the JDK?
