RE: Starting out question.

This is a pretty common problem, one discussed many times here.  One discussion was very useful.  I am copying the replys from Wanda Cummings and David Wall into this note.  Hope it helps.

i had the same problem, i got this answer, and it worked.

Your classpath does not include the Toolbox access classes.  Add
"/QIBM/ProdData/HTTP/Public/jt400/lib/jt400.jar" to your classpath
and you should be set.  There are a couple of ways to do this.  In
your example you use the -classpath parm of the Java command.  You
can change that to
   "java -classpath /myjava:/QIBM/ProdData/HTTP/Public/jt400/lib/jt400.jar
ShowMeClas"
or setup up the CLASSPATH environment variable once in QSHELL by entering
command
"export -s CLASSPATH=
/myjava:/QIBM/ProdData/HTTP/Public/jt400/lib/jt400.jar"

Since you talk about QSHELL you must be running on the AS/400.  Make sure
the Toolbox container you use (jt400.jar or jt400Access.zip) has an
associated
Java program.
This will make java programs run much faster.
