Use a Java object from PB (using the Microsoft JVM)

Use the Microsoft javareg utility to register a java class as a COM server. Once registered, the Java class will be visible from all languages that can deal with COM objects. I am giving here some examples in VbScript, JScript, ASP and Powerbuilder.
NOTE: The class can compiled with any JDK but the actual execution will use the Microsoft JVM installed on the system.
The javareg utility is part of the Microsoft Java SDK which can be freely downloaded from the Microsoft Web site.
First a simple Java class.
[JavaSays.java]
package JavaCom;
public class JavaSays {
public String Hello() {
return "Hello world" ;
}
public String Say(String what) {
return what ;
}
}
Then this BAT file is executed to register our class.
javareg /register /class:JavaCom.JavaSays /progid:JavaCom.JavaSays
md c:\Windows\Java\TrustLib\JavaCom
copy JavaSays.class c:\windows\java\trustlib\javacom
That's it. The system now has a COM object called JavaCom.JavaSays installed.
