Unable to run the java class from php using PHP-Java Bridge

I am calling a java class from PHP program using Php-Java Bridge and I am using the Tomcat server. Where I have created a Jar file of my java program and put it in C:\Tomcat 8.5\webapps\JavaBridge\WEB-INF\lib this folder and my small PHP script which call java program resides in C:\Tomcat 8.5\webapps\test folder My jar file name and java class name is same.

File Name: NewFIle.java

import java.io.File;
import java.io.IOException;

public class NewFile {
   public static void main(String[] args) {
      try {
         File file = new File("E:/myfile");

         if(file.createNewFile())System.out.println("Success!");
         else System.out.println ("Error, file already exists.");
      }
      catch(IOException ioe) {
         ioe.printStackTrace();
      }
   }
}

File Name: test.php

<?php 

require_once("java/Java.inc");
// echo java("java.lang.System")->getProperties();

echo java("NewFile");

echo "Hello";
// print_r($data);
?>

I am getting an empty output problem to seem where I am calling java program, the java program which I wrote is creating a normal file in a particular file location.

Please Let me know what i am doing wrong any suggestion will be accepted. I know about PHP exec command but I am not able to execute with PHP-JAVA bridge
