Example: Using JobList to get a list of jobs

///////////////////////////////////////////////////////////////////////////
//
// This program is an example of the "job" classes in the
// IBM Toolbox for Java.  It gets a list of jobs on the server
// and outputs the job's status followed by job identifier.
//
//
// Command syntax:
//    listJobs system userID password
//
// (UserID and password are optional)
