You need to set a ENVIRONMENT Variables to your java installation folder..

You need to set your in two ways.



1) PATH :- this will set your compilation path



step 1: goto Start--> Control Panel --> click on System

step 2: In the System Properties, click on the Advanced tab--> and click on the Environment Variables button in the bottom

step 3: In the Environment Variables , goto the system variable..

select the PATH and edit. You will be opened a popup with Edit System variables--> in the variable value .. add semicoln (;) and add your java installed bin location like (C:\Program Files\Java\jdk1.6.0_16\bin)

step 4:- Click ok to close all windows.



2) CLASSPATH :- this will set your run path



Follow the above steps through 2 and in third step you need to open CLASSPATH and edit. You will be opened a popup with Edit System variables--> in the variable value .. add semicoln (;) and add your java installed lib location like (C:\Program Files\Java\jdk1.6.0_16\lib)

The java compiler comes with the Java SDK, not the JRE. Make sure you have the SDK and not the JRE version.
