Yes it is! I've exactly the same problem. if u've Windows XP, Ya must go to control panel, performance and Maintenance, System, Advanced, Environment Variables, System Variable. Goto Path, click Edit. Now its here that changes must be made, if any, they say ya should leave everything but after bin type the following ;C:\Program Files\j2sdk_nb\j2sdk1.4.2\bin
then, type java -version, hit return then ya should get something like
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition(build 1.4.2-
Java HotSpot(TM) Client VM (build 1.4.2-b28,mixed mode)
it's something like that, it should be almost similar anyway.
However, I typed javac then and got
'javac' is not recognised as an internal or external command,
operable program or batch file.
It's is a nightmare trying to solve this but I know that the problem is with the Class Path Environment variable.
