Re: Use of Runtime.getRuntime().exec

[Fred Kulack <kulack@xxxxxxxxxx>]

Not in particular a cobol program, but this should get you started.
Runtime exec simply runs any QSH command (parameters included).
The QSH system command outputs spooled files created by the CL
command as normal output (but obviously at the _end_) of the command.

import java.util.*;
import java.io.*;
public class CmdExec {
   public static void main(String[] args) {
      try {
         int count = 0;
         int i;

         Vector match = new Vector();
         String cmd = "system \"WRKCMTDFN JOB(*ALL) STATUS(*XOPEN) OUTPUT
(*PRINT)\"";
         boolean end = false;

         System.out.println(cmd);
         Process p = Runtime.getRuntime().exec(cmd);
         InputStream is = p.getInputStream();
         InputStreamReader ir = new InputStreamReader(is, "Cp037");
         BufferedReader buf = new BufferedReader(ir);
         count = 0;

         while (!end) {
            String s = buf.readLine();
            if (s == null)
               end = true;
            else {
               System.out.println(s);
               if ((i = s.indexOf("Global transaction identifier")) != -1)
{
                  // this line has gt id
                  int j = s.indexOf("X", i);
                  String gtid = s.substring(j);
                  System.out.println("gtid =" + gtid);
                  match.addElement(gtid);
                  count++;
               }
               if ((i = s.indexOf("Branch qualifier")) != -1) {
                  // this line has bqual
                  int j = s.indexOf("X", i);
                  String bqual = s.substring(j);
                  System.out.println("bqual =" + bqual);
                  match.addElement(bqual);
                  count++;
               }
            }
         }
         System.out.println("total matches=" + match.size());
      }
      catch (Exception e) {
         e.printStackTrace();
      }
   }
}
