Re: Scheduling a Java PGM to run...

    Hi Mike,

    I agree with Paul.  We have a client that runs detail and summary
billing every day using the job scheduler.  While I could see a rationale
for occasionally executing jobs via the web, especially if you don't have a
5250 emulator or Java program to execute the commands, here the job
scheduler does exactly what you need and you don't have a batch job
intermixed with your web processing.

    The base CLLE we use to run jobs looks like

 /* Pgm calls Java app                               */
 /*  must be ILE CL to work properly                 */

              PGM
 /* Invoke PGM with proper arguments  */
              JAVA       CLASS(MyClass) PARM(anArgString) +
                           CLASSPATH('/dirForMyClass:/qibm/proddata/ja+
                           va400/jt400ntv.jar:')
 END:
              ENDPGM


    Multiple directories, if needed, are separated by colons, not
semicolons, as shown above.  HTH,
