HI

you supposed to set the jdk path (like C:\Program Files\Java\jdk1.6.0_22\bin) in environment variable.
go to my computer property->advanced->Environment variable-> click on New -> put 'path'in first text box and jdk path like 'C:\Program Files\Java\jdk1.6.0_22\bin' in second text box.
than OK.

i think you can do it.
