Re: D-Specs for Java Prototypes in RPG

Think of a class like a service program. A service program does not return anything but the functions (methods) inside do. A package is a group of classes (service programs) so when you code it you first refer to the package and then the class inside that package and then the method inside that class. You also may need th change your enviromnet variable CLASSPATH so it can find the classes 

An example:
ADDENVVAR CLASSPATH '/home/myclasses:/home/mypackages:/home/myjarfiles/j1.jar'Here is some more info:
If the Simple class file is /home/myclasses/Simple.class, you would specify the directory /home/myclasses in your CLASSPATH environment variable, and you would specify 'Simple' as the class name in your RPG keywords.
If the PkgClass class file is /home/mypackages/MyPkg/PkgClass.class, you would specify the directory /home/mypackages (the directory containing the package) in your CLASSPATH environment variable, and you would specify 'MyPkg.PkgClass' (the package-qualified Java class) as the class name in your RPG keywords.
The class name for your RPG keywords is the same name as you would specify in your import statements in your Java classes. You use the CLASSPATH environment variable to specify the location of the class files, or the location of the directory containing the package.

Subject: D-Specs for Java Prototypes in RPG
I've been experimenting with using java within RPG programs. Curious about two issues. 

#1)
In the IBM Manuals it shows void method being coded as:
D pkgMethod       PR                  EXTPROC(*JAVA
D                                           : 'Pkg.PkgClass'
D                                           : 'method')
There's no "CLASS" entry needed. But when I try to code a void method like this: 
     * Open Document Method  (returns void)
    D opendoc         PR              O   ExtProc(*JAVA:
  D                                     'com.lowagie.text.Document':
    D                                     'open')
The WDSc syntax checker keeps telling me I need to declare a "CLASS", but there is no class to come back. 

#2)
I can't find anything in the IBM manuals relating to method calls that return primitives. I need to call a method that return boolean (not Boolean). How does one code the prototype's CLASS entry when the return value is not a class? 

Thanks,

Larry
