Re: Running Java in a batch Job

Hello,

The classpath must be specified in the CL program.

PGM PARM(&DATEFIC)
DCL VAR(&DATEFIC) TYPE(*CHAR) LEN(4)
RUNJVA CLASS(aal.Bnf) PARM(&DATEFIC) +
CLASSPATH('+
/homepgm:+
/homepgm/outils/Chaine:+
/homepgm/acces/ConnexionBatch:+
') OPTION(*VERBOSE) OUTPUT(*PRINT)

ENDPGM

In this example, the class Bnf.class is stored in the IFS at /homepgm/aal/
I call aal.Bnf, so I put the path to the base package first (/homepgm:)
I also add the path to all packages I may use outside of the base package, and all .jar I might need, all separated by :
All parameters will be available in the java program as args[]
Option verbose provides a spool file with all classes opened and error messages, I use it only in test mode.
Hope it helps.

Best wishes,

Marie-Line

I am using an autostart job entry to run the runjva command in a CL Program. I guess I could use STRQSH? in the program. Do you have a small example?

I should be ashamed, but I've never actually used RUNJVA. I've always used QSH in the SBMJOB command and done all my setup in a shell script where the last entry is the java command line.

Thanks for that information. I am using the RUNJVA command to start my class in my batch job but it is not finding my class. Does RUNJVA look in the current directory or do I need to specify the full path name to my class?

I've not done this myself, but it would help my application, so I looked it up.

To monitor for ENDSBS or ENDJOB use Runtime.addShutdownHook().

I found this in an old APAR report associated with a V5R2 PTF. Assumably, all releases since then will have the functionality.

To All:


I finally have my Java environment setup to run the J9 Java6 JVM and the Classic 1.4 JVM in separate worlds and can run either JVM by setting my JAVA_HOME ENVVAR. My question now is what is the best way to start a Java jar file from within a CL batch job and what is the cleanest way of ending the job when an ENDSBS command is processed? Thanks for all of your help so far.
