More class path

I have read the entries about class path and understand that you no longer
use the environment method to set the path and now you enter the path at the
execution of you application.
What I don't know is where should I point my class path?
My path to Java is:

C:\Program Files\Java\sdk1.5.0_06

What do I add to that?
I am running WinXP

Thanks Bob Wright

Bob,

You can specify the classpath from the java executable using the -cp
switch. For example:

> java -cp somewhere MyProgram

Where somewhere is your classpath (holding classes) and MyProgram is the
java class you want to execute (the one with a static main method).

Where you 'point' your classpath depends on what classes & jars you want
access to.

For example, within a particular projects directory, I create another
called class.
I compile everything like this:

> javac -d class MyProgram.java

This dumps the class files into the class directory. Then to run the
program I use this:

> java -cp class MyProgram

The benefit is that it keeps all the .class files away from your .java
source files. A bit tidier I reckon.

You can also use the -cp switch to include jars

> java -cp class:someJar.jar MyProgram.

Hope that helps, if not, perhaps provide a bit more info on what you are
trying to do.
Andy
