Using command prompt and Notepad

[paralinx]

Hey all,

I have a book that tells you how to use the command prompt and notepad to run java code. But, when it tells me to run this line in the command prompt it says that its not a found function:

javac HelloWorld.java (which is supposed to compile the java file)

Does anybody know why this doesn't work?

JDK Class path property is not set or set improperly, search this forum and you'll find the right way to do it

search what? command prompt java?

1- Open System properties (Control Panel==>System)
2- Go to the "Advanced tab"
3- Click on the "Environment vars" button
4- In the "System vars" table, make sure you have "CLASSPATH" variable with the value set to the folder containing java JDK

I do have that.
