Running Java in Linux Terminal

[Bob Smith]

If you're using bash or korn shells you can set the classpath 
environment prior to running java, which could also get you around the 
errors that you are experiencing. 

Java must know the location of any package or packages or group of 
classes that you are going to call during the execution of an 
application, with the exception of the normal Java runtime class 
libraries.  The three options to using Java classpaths are to set the 
entire classpath on the command line ( java -cp [paths] classnames), set 
the classpath in the environment (export CLASSPATH=path1:path2...) or to 
run java from the root class directory that you are using.  I'm not 
going to get into jar file names and packages etc, because that's a 
whole nuther tutorial.

My recommendation is to acquire a good book, or more, on Java.  The Core 
Java Vol.1 book covers extensively how to run Java with various 
classpath definitions, and it's an excellent primer.  There are other 
good books out there too numerous to mention.
