[hero69]

Hi

I have a problem when I will invoke a java class from Enterprise Cobol 3.2 (IBM). I get a system code 0019 and user code 0000.

cbl dll,thread
Identification division.
Program-id. "TSTHELLO" recursive.
Environment division.
Configuration section.
Repository.
Class HelloJ is "HelloJ".
Data Division.
* Set address of JNIEnv to JNIEnvPtr
* Set address of JNINativeInterface to JNIEnv
Linkage section.
* COPY JNI
Procedure division.
Display "COBOL program TSTHELLO entered"
Invoke HelloJ 'sayHello'
Display "Returned from java sayHello to TSTHELLO"
Goback.
End program "TSTHELLO".

Compiler and Options:
//COMPILE EXEC PGM=IGYCRCTL,
// PARM='SIZE(5000K),RENT,DLL,THREAD,DBCS,LIB'

Java-Class:
class HelloJ {
public static void sayHello() {
System.out.println("Hello World, from Java!"
}
}

Has someone any idee what the problme is?
