Here's the error message that matters:

Could not find Class com.dovetail.jzos.ZUtil

This is because your CLASSPATH is not set correctly. (From the log), is set to:

CLASSPATH=:/tmp/jzos/jzos/*.jar:

This is because the following line in the script couldn't find the directory:

for i in "${JZOS_HOME}"/*.jar; do

So, check to see that /tmp/jzos/jzos is where the JZOS_HOME directory is really located.

Hello,

/tmp/jzos/jzos is where JZOS is installed...I passed this to one of our developers who fixed it; he wrote :

It seems that the "unix script" embedded in the sample JCL dosent seem
to want to work on our installation. I'm not sure why. It is a simple
change to get it working, and it has to do with the FOR loop that is in
the script looking for .jar files in the jzos installation folder. There
must be a simple typo there somewhere but I couldn't find it. Anyways,
there is only one jar file need so I referenced it directly.

Thanks

We have been distributing this configuration script in the sample JCL for some time and this is the first report of a problem. Check to make sure that your job's unix userid has both read and execute permission to the directory.

From: http://www.unix.org.ua/orelly/networkin ... h05_04.htm

If you have execute access to a directory but do not have read access, you cannot list the names of files in the directory (e.g., you cannot read the contents of the directory). However, if you have access to individual files, you can run programs in the directory or open files in it. Some sites use this technique to create secret files - files that users can access only if they know the files' names.
