How to call Java application from php script

Create and test your Java desktop application.

1. Create a simple application,
   HelloWorld.java
   , which just displays a "hello world" dialog box:
   
   
   
   
   
   
   
   import javax.swing.JOptionPane;
   
   
   
   public class HelloWorld {
   
     public static void main(String args[]) throws Exception {
   
       JOptionPane.showMessageDialog(null, "hello world");
   
       System.exit(0);
   
     }
   
     public void hello(String args[]) throws Exception {
   
       JOptionPane.showMessageDialog(null, "hello " + args[0]);
   
   
     }
   
   }
   
   
   
   
   
   Create a manifest file,
   MANIFEST.MF
   , with the following content:
   
   
   
   
   
   Main-Class: HelloWorld
   
   
   
   
   
   
   
   
   
2. Compile and run your Java application. Open a command shell and type:
   
   
   
   
   
   
   javac -Djava.ext.dirs=. HelloWorld.java
   
   jar cvmf MANIFEST.MF HelloWorld.jar HelloWorld*.class
   
   java -jar HelloWorld.jar
   
   
   
   
   

Add the PHP/Java Bridge library to your Java application

1. Copy JavaBridge.jar to the current directory.
   
   
   
2. Add
   JavaBridge.jar
   to your Java application. Edit the manifest
   MANIFEST.MF
   like this:
   
   
   
   
   
   
   Main-Class: HelloWorld
   
   Class-Path: JavaBridge.jar
   
   
   
   
   
   
3. Open a communication port for PHP. Edit
   HelloWorld.java
   like this:
   
   
   
   
   
   
   import javax.swing.JOptionPane;
   
   
   
   public class HelloWorld {
   
     public static final String JAVABRIDGE_PORT="8087";
   
     static final php.java.bridge.JavaBridgeRunner runner =
   
       php.java.bridge.JavaBridgeRunner.getInstance(JAVABRIDGE_PORT);
   
   
   
     public static void main(String args[]) throws Exception {
   
       runner.waitFor();
   
       System.exit(0);
   
     }
   
   
     public void hello(String args[]) throws Exception {
   
       JOptionPane.showMessageDialog(null, "hello " + args[0]);
   
     }
   
   }
   
   
   
   
   
   
4. Recompile your Java application.
   
   
   
5. Run your Java application. This time your application doesn't display anything and doesn't return.
   
   
   
6. Create a PHP test script. For example:
   
   
   
   
   
   
   
   <?php
   require_once("http://localhost:8087/JavaBridge/java/Java.inc");
   
   
   
   $world = new java("HelloWorld");
   
   echo $world->hello(array("from PHP"));
   
   ?>
   
   
   
   
   
   
7. Open a new command shell and run your test script. For example with:
   

   
   

   
   
   php -n -dallow_url_include=On test.php
   
   

   
   

   
   
8. Your PHP script has called the method hello(), which should display a message dialog.
   
9. Note that the above code doesn't create a application-modal dialog. The communication can be traced by starting your application with the options:
   java -Dphp.java.bridge.default_log_file= -Dphp.java.bridge.default_log_level=4 -jar HelloWorld.jar
