Aaron, Thanks for the tip. I already had the system default properties set to 1.4. In testing, I logged off and logged back on -- and only made this RPG call. Same problem. Any other ideas?

In the end it has to do with the default JRE that is being found and the wrong one can be selected for a variety of reason I have yet to figure out. Some things to check on would be if there are other applications currently running that would have already initiated a JVM that is somehow tied to your job.

When I call the Java program from the RPG, I get an error that was traditionally thrown when the Java program was compiled using a newer JDK than the JRE running the program. this exception is: Cause . . . . . : RPG procedure CRD002RTST in program MSILVERS/CRD002RTST received Java exception "java.lang.NoSuchMethodError: append (Ljava/lang/StringBuffer;)Ljava/lang/StringBuffer;" when calling method "<init>" with signature "()V" in class "com.shipley.ssl.CRD001J". I compiled the Java program on the System i using the JDK 1.4.2. I added a line in the program to run the command JAVA *VERSION to determine the JVM while the program is running -- it is using 1.4.2. Now for the strange part -- if I run the Java program from the command line using RUNJVA, the program runs with no problem. The only time I have a problem is when I run the program from an RPG program. I have stripped out everything in the RPG program to include only the bare minimums. My code is as follows: * Define object D crd001j S O Class(*JAVA: D 'com.shipley.ssl.CRD001J') * Define the Constructors D constr_crd001j PR O ExtProc(*JAVA: D 'com.shipley.ssl.CRD001J': D *CONSTRUCTOR) * D string PR O ExtProc(*JAVA: D 'java.lang.String': D *CONSTRUCTOR) D value 100A CONST VARYING * * string array for main class call..... * D args S O Class(*JAVA:'java.lang.String') D *CONSTRUCTOR) * D string PR O ExtProc(*JAVA: D 'java.lang.String': D *CONSTRUCTOR) D value 100A CONST VARYING * * string array for main class call..... * D args S O Class(*JAVA:'java.lang.String') D DIM(2) * * Define the main method - passing in one parameter D main PR ExtProc(*JAVA: D 'com.shipley.ssl.CRD001J': D 'main') D STATIC D O Class(*JAVA:'java.lang.String') D CONST D DIM(2) * * Define the main method - passing in one parameter D main PR ExtProc(*JAVA: D 'com.shipley.ssl.CRD001J': D 'main') D STATIC D O Class(*JAVA:'java.lang.String') D CONST D DIM(2) D OPTIONS(*VARSIZE) * D setdebug PR ExtProc(*JAVA: D 'com.shipley.ssl.CRD001J': D 'setDebug') D N Value * /Free // change the environment variables before the JVM is created commandstring = 'CHGCURDIR DIR(' + QUOTE + '/creditssl' + QUOTE + ')'; JCLCommand(commandstring); commandstring = 'ADDENVVAR ENVVAR(CLASSPATH) VALUE(' + QUOTE + '.:/creditssl/jt400Native.jar' + QUOTE + ') REPLACE(*YES)'; JCLCommand(commandstring); commandstring = 'JAVA *VERSION'; JCLCommand(commandstring); // constructor..... crd001j = constr_crd001j; // set the debug option setdebug(crd001j:*ON); // call the main class -- it will print out info in the log.... args(1) = string('Test 1'); args(2) = string('Test 2'); main(args); /End-free Any ideas???? ======================================= Mike Silvers, Chief Operating Officer Hainey Business Systems-Division of Affinigent, Inc IT Solutions for Business Performance Cell: (717) 324-5508 Phone: (717) 600-0033 ext 106 Fax: (877) 804-9589 http://www.affinigent.com <http://www.affinigent.com/> http://www.hbs-inc.com <http://www.hbs-inc.com/> AIM: IBMJavaMan Skype: hbs_mike_silvers ======================================= -- This is the RPG programming on the AS400 / iSeries (RPG400-L) mailing list To post a message email: RPG400-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/rpg400-l or email: RPG400-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/rpg400-l. -- This is the RPG programming on the AS400 / iSeries (RPG400-L) mailing list To post a message email: RPG400-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/rpg400-l or email: RPG400-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/rpg400-l.
