RE: Compiling Hello.java with javac ?

As David suggests, you are far better off starting out on the PC.  In
QShell, the problem you are describing could be do to issues in file
naming, directories, classpath, who knows what.  If you insist on
pushing through with this, I would suggest one quick check: execute the
command "ls" (no quotes).  This will list the contents of the current
directory.  If hello.java is there, you can compile it.  But notice also
that you named the file incorrectly anyway.  It would have to be named
"HelloWorld.java" in order to compile.

I highly suggest installing WDSC on your PC and starting there.  There
is no tool out there like WDSC.  WDSC stands for WebSphere Studio Client
for iSeries and if you have an iSeries that has a current license to the
compilers (5722WDS) then you can get a copy of WDSC.
