VBJ 5.2 How to start irep from within a Java application?

Problem:

How to start irep from within a Java application?

Resolution:

The following code demonstrates how to startup irep inside a JAVA application.
 

package testirep;
 
import com.inprise.vbroker.compiler.tools.tool;
 
class Startup {
 /* Method to startup any JAVA based tool */
 static void startTool(String[] args)
 {
   System.err.println("Called for " args[0] " !");
   com.inprise.vbroker.compiler.tools.tool.main(args);
 }
 
 /* Test this method through process startup */
 public static void main(String[] args)
 {
   Startup.startTool(args);
 }
};

 
It consists of two static functions:

(a) startTool, which starts tools using arguments passed in.
** This is the function that can be copied into the Application code and the
** incoming parameter array can be replaced with "hardcoded" values.

(b) main, which starts the above function with the parameters given on the command line.
** This can be used to explore the correct arguments. However,
** this type of startup is exactly used by the "irep.exe" and the equivalent scripts
** on UNIX boxes.

To test this:
1. Compile this code:
"vbjc testirep/Startup.java" for 5.2

"vbjc -VBJaddJar vbdev.jar testirep/Startup.java" for 8.x
 
2. To start the irep do:
"vbj testirep/Startup irep -fe com.inprise.vbroker.ir.irep" for 5.2

"vbj -VBJaddJar vbdev.jar testirep/Startup irep -fe com.inprise.vbroker.ir.irep" for 8.x
 
After initialization, the IREP tool should be up and running. Other tools like idl2ir can also be started in a similar manner.
