How to run Java code using SAS (WPS) without JCL

Am try to call the java application using mainframe SAS 9.1 (WPS). Its a simple hello world program in which Java application will return some value/outfile. I need to read the same via SAS and comparing the result with existing values.

But when i try to execute it hits an error :
ERROR: Could not find JREOPTIONS entry for "-Dwps.jre.libjvm="

Since this is a mainframe sas , as posted in other blogs i am not able to set the class path .

On the other hand we are able to access java via JCL through a proc but i need the same via sas .

My code :

/*options jreoptions =(-Djava.class.path= */
/*jreoptions =(-Djava.class.path=
"/u/siva/BatchJava/lib/apps/helloWorld.jar") ; */
proc options option=jreoptions;
run;
/*%INCLUDE 'SYSS.P.COZEEE.PARMLIB(COZCFGD)'; */

proc javainfo; run;
endsas;

%macro init_classpath_update;
     DATA _null_;
         LENGTH path_separator $ 2
                 orig_classpath $ 500;
                 path_separator = '/';
         DECLARE JavaObj f("java.io.File", "");
         f.getStaticStringField("pathSeparator", path_separator);
         orig_classpath = STRIP(SYSGET("CLASSPATH"));

        IF _ERROR_ = 1 OR LENGTH(orig_classpath) = 0 THEN DO;
            PUT "NOTE: Ignore any messages from the next statement(s)";
            orig_classpath = "";
        END;
        CALL SYMPUTX('CP_orig_classpath',
                      STRIP(orig_classpath), 'GLOBAL');
        CALL SYMPUTX('CP_path_separator',
                      COMPRESS(path_separator), 'GLOBAL');
    RUN;
%mend;
%macro add_to_classpath(cp_addition);
    DATA _null_;
        LENGTH current_classpath $ 500
                new_classpath $ 500;
        current_classpath = STRIP(SYSGET("CLASSPATH"));
        IF _ERROR_ = 1 OR LENGTH(current_classpath) = 0 THEN DO;
        PUT "NOTE: Ignore any messages from the nearby statement(s)";
            new_classpath = "&cp_addition";
        END;

         ELSE DO;
             new_classpath = COMPRESS(current_classpath) ||
                             "&CP_path_separator" || "&cp_addition";
         END;
         CALL SYMPUTX('CP_new_classpath', STRIP(new_classpath),'GLOBAL');
     RUN;
     %PUT NOTE: Setting Java classpath to &CP_new_classpath;
     OPTIONS SET=CLASSPATH "&CP_new_classpath";
%mend;
%macro reset_classpath;
     %PUT NOTE: Setting Java classpath back to its
     original state: &CP_orig_classpath;
     OPTIONS SET=CLASSPATH "&CP_orig_classpath";
%mend;


%init_classpath_update;
%add_to_classpath(/u/siva/BatchJava/lib/apps/helloWorld.jar);

data _null_;
/* -- set length of variable to capture message ; */
length message $ 200 ;
/** -- initiate java object ; */
declare javaobj jobj ("helloWorld");
/* -- get message and clean up ; */
jobj.callStringMethod('getMessage', message);
jobj.delete();
put message = ;
run;
%reset_classpath;

If you're using WPS, the "JavaObj plumbing" is likely to be different than what SAS supports. You might need to work with WPS support to find the answer to this question in your environment.
