Re: Calling a Java pgm from RPG

Ramprasad,

You need to link your java class file to your RPG program like so...

d javaString      s                   o   class(*java:'java.lang.String')
d parm1           s                   o   like(javaString)
d parm2           s                   o   like(javaString)
d returnValue   s                500a varying
...
d myclass       pr              o   class(*java: 
d                                     'java.lang.String') 
d                                     extproc(*Java 
d                                     :'my.package.name.MyClass'
d                                     :'methodName') 
d                                     static 
d  parm1                             like(javaString) 
d  parm2                             like(javaString) 
d new_String      pr                  like(jString) 
d                                     extproc(*JAVA 
d                                     :'java.lang.String'
d                                     :*CONSTRUCTOR) 
d create_from                 1024A   varying const 
d getBytes        pr          1024a   varying 
d                                     extproc(*JAVA: 
d                                     'java.lang.String':
d                                     'getBytes') 
...
 /free
 parm1 = new_String('Test1');
 parm2 = new_String('Test2');
 javaString = myclass(parm1:parm2);
 returnValue = getBytes(javaString);
 /end-free

hope I didn't leave anything out...

Calling a Java pgm from RPG







Hi guys,
 
I have a java .class file in /testdir. I want to invoke that class file 
from
RPGILE.
The java pgm accepts 2 parameters and I should get the value back to 
RPGILE
pgm...
Can anyone provide me detailed steps to execute this...?
 
Thanks & Regards,
Ramprasad V
