How to run a batch file of an application that takes images as arguments in java

I have a batch file run.bat that requires many arguments for it to run. It is a part of an application named GeoMatch for which I have GeoMatch.exe present in the same folder as the .bat file.

In order to run the application, I need to run the batch file.

By using command prompt in Windows , I run the batch file as follows:

 C:\programs\test\GeoMatch_demo>GeoMatch -t template.jpg -1 10 -h 100 -s search1.
 jpg -m 0.7 -g 0.9

I get my desired output. However, when I try to run the same from my Java Application I am not getting the desired result.

My Java code:

   import java.io.*;
   import java.lang.*;

  public class BatchDemo
    { 
       public static void main(String args[]) throws IOException
      { 
        try{
         String cmd;

           try { 

         String[] command = { "cmd.exe", "/C", "Start", "C:\\programs\\test\\GeoMatch_demo\\run.bat","C:\\programs\test\\GeoMatch_demo\\Search1.jpg","C:\\programs\\test\\GeoMatch_demo\\template.jpg"};
           Runtime r = Runtime.getRuntime();
           Process p = r.exec(command);
           p.waitFor();

            } catch (Exception e) 
            {

            System.out.println("Execution error");} 
        }
      catch(Exception e)
       {
     e.printStackTrace();
      }
  }
}

Also to run this .bat file we require 3 DLL's to be present in the same folder as the .bat file. I have added those 3 DLL's in my Java Project but still I don't get the desired result.

can someone help me ?

Thanks in advance

Try to add the path C:\programs\test\GeoMatch_demo into PATH environment variable.

when you execute the bat file from the java code you do not change the current directory in the cmd, meaning that you are not actually in C:\\programs\\test\\GeoMatch_demo\\. So the exe file can not be found. If you refer to the exe file with absolute path in the batch file, the problem should go away.
