I wouldn't try learning this on an iSeries, unless all you have is a dumb 
terminal.

You could compile a very simple class, like HelloWorld without your 
classpath set, but you will not be able to run it.

Your classpath is not correct.  At a minimum, it needs to include /Java. 
You can also do a CHGCURDIR to /Java prior to entering QShell.  Then just 
make sure that '.' is in your classpath.

The reference to the ../jt400/lib folder in your classpath is also not 
correct.  You can only put folders in your classpath if the folder 
contains .class file (including the package directories).  "lib" folders 
typically contain JAR files.  JAR files have to be specifically added to 
your classpath. 

So, let's assume that you want jt400.jar in your classpath for some 
reason.  Your classpath environment variable should look like this:


/Java:/QIBM/ProdData/HTTP/Public/jt400/lib/jt400.jar:
/QIBM/ProdData/HTTP/Public/jt400/lib/data400.jar:
/QIBM/ProdData/HTTP/Public/jt400/lib/x4j400.jar

And you could possibly have replaced /Java with a single dot, provided 
your current directory was /Java.
.:/QIBM/ProdData/HTTP/Public/jt400/lib/jt400.jar:
/QIBM/ProdData/HTTP/Public/jt400/lib/data400.jar:
/QIBM/ProdData/HTTP/Public/jt400/lib/x4j400.jar

As a newbie to Java on the 400, I am perplexed by the classpath issue. I
simply want to run the HelloWorld program from a command line. I have
the source in /Java. From within QSH, I did a "cd /Java, and then a
javac HelloWorld.java". 
The compile was successful and the class file now exists in /Java. When
I do a java HelloWorld, from within QSH OR from a OS/400 command line, I
get all sorts of errors. The first being
"java.lang.NoClassDefFoundError". 
What I don't understand is if I am able to compile the program, doesn't
that mean that the classpath is set correctly and I should be able to
run it without any problems?  Any suggestions would be greatly
appreciated. By the way, if it helps, my CLASSPATH ENVVAR is set to
"'/QIBM/ProdData/HTTP/Public/jt400/lib/'"
