[ale] Java Help

[Terry Lee Tucker]

Hello ALE:

I'm completely new to java.  I'm trying to run a simple "Hello World"
type program on my RedHat 4.2 system. I have no idea how to setup the
environment. I am trying to compile a java file called first.java. When
I type the following command I get an error.
$ javac first.java
$ No library path set.
$ Cannot find essential class 'java/lang/Object' in class library ...
aborting.

Can anyone help?
