RE: execute a java program from a cl-program

This CL works for me
Obviously you won't need/have the same jar files and hopefully you'll be on
a later version of JDK than 1.1.8 but it does work!

PGM PARM(+
         &i_dtaqlib +
         &i_rcvdtaq +
         &i_key +
         &i_dtlpgm +
        )
/* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
*/

/* Program parameters:
*/

DCL &i_dtaqlib  *CHAR 10   /* Library containing data queues
*/
DCL &i_rcvdtaq  *CHAR 10   /* Data queue to receive messages
*/
DCL &i_key      *CHAR 9    /* Key
*/
DCL &i_jar   *CHAR 10   /*used to set jar file             */

DCL &jarfile    *char 32   /* .jar file for INVESCO java classes
*/
DCL &classpath  *char 1000 /* Java classpath
*/

/* --------------------------------------------------------------------
*/

/* Detailed Processing
*/

/* set current directory
*/

CHGCURDIR '/java'

/* set jar file to use depending on incoming parm
*/

if (&i_jar = '*PROD') CHGVAR &jarfile 'live.jar'
else if (&i_jar = '*TEST') CHGVAR &jarfile 'test.jar'
else CHGVAR &jarfile 'developing.jar'

/* set class path & jar file
*/

CHGVAR &classpath ('.:/QIBM/ProdData/Java400/jdk118/lib/classes.zip' +
          *CAT ':jt400.jar:mail.jar:activation.jar:' *CAT &jarfile )

/* invoke java with parms & classpath
*/

   RUNJVA CLASS('queue/AS400QueueHandler') +
          PARM(&i_key +
               'email.FileEmailer' +
              ) +
          CLASSPATH( &classpath )

ENDPGM

Subject: execute a java program from a cl-program


hi,

i try to execute a java program in a cl-program but i always get an error
message. i try to run the program classpath.java which only prints out the
classpath. it runs in the qshell with no problems. but in a cl program i
get the error:

java.lang.NoClassDefFoundError: classpath
      java/lang/Throwable.<init>(Ljava/lang/String;)V+4 (Throwable.java:81)
Java-Programm mit Ausgangscode 1 beendet


CL-Programm:

PGM

RUNJVA     CLASS(classpath) PARM('-cp /tmp/classpath')

ENDPGM

the classpath java- and class-files resides in the folder /tmp/classpath

a little example would be nice. thanx.
