Java error while starting Alice3 - Solution

I have faced the following problem when I tried to run Alice 3 in one computer running Windows XP at one of the venues where I conducted the workshop. I am sharing it as it may be helpful to some of our friends who might have faced same problem.

Problem: 
When you double click on the Alice 3 shortcut, a command window opens saying "java isn't recognized as a internal or external command, operable program or batch file" install java.

Solution: 
Right click on My Computer select properties and click on Advanced tab.
You will find a button environment variables at the bottom. Click on it and under system variable edit path variable to add the path to the bin directory under java folder (eg. C:\Program Files\Java\jre7\bin). Do not remove the other values in the path variable box, just add this at the end after the last semi colon ( ; )
The same may happen in Windows Vista and 7 and the solution is the same.
