New to Java

Hi all,

I forgot a lot about Java, and need to relearn a few things. I had a JRE (5.0_06) already installed, and installed the JDK (1.5.0). It seems to me I do not need to use the "old" JRE. Comments? But first things first, I use XP Home SP 2.

I am now doing a Wireless Development Tutorial where I had to install Tomcat. In the tutorial it says I need to set my classpath. It now points to the JRE (.;D:\Program Files\Java\jre1.5.0_06\lib\ext\QTJava.zip). Where should I point it to if I want to use the JDK instead of the JRE? To .;D:\Program Files\Java\jdk1.5.0\lib\ ?

Next, I should be able to compile a simple program. But when I type javac, I get "'javac' is not recognized as an internal or external command". How come?

I sat my JAVA_HOME in the System Properties (Advanced tab, Environmental Variables). I should think that would be enough to let the system find the javac program. The system does not agree with me, so who can enlighten me?
