V. Deploy your PHP and Java file

In this chapter, I will not talk detail about how to create and run Java.
If you are curious about how to create PHP that executes Java, check PHP/JavaBridge site.

1. Create Java Hello World

1.1. Open eclipse and create Java Project.
1.2. Create HelloWorld.java file under the project.

import javax.swing.JOptionPane;

public class HelloWorld {
    public static final String JAVABRIDGE_PORT="8080";
    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]);
    }
}

1.3. Create MANIFEST.MF

Main-Class: HelloWorld
Class-Path: JavaBridge.jar

1.4. Add JavaBridge.jar into Build Path.
Right click on the project and go to Build Path.
Add JavaBridge.jar file on library tab.

1.5. Built and Run
Make sure Project -> Build Automatically is checked on eclipse.
Right click on your project, and choose Run -> Java Application.

You will see no result, and it is ok for now. Just make sure it run without error.
1.6. Create TestBridge.jar file.
Right click on the project and choose Export to the executable jar file.

2. Create test php file

Create mytest.php under JavaBridge folder, which contains following code.

<?php
require_once("http://localhost:8080/JavaBridge/java/Java.inc");

$world = new java("HelloWorld");
echo $world->hello(array("from PHP"));
?>

3. Deploy jar file

Place TestBridge.jar under JavaBridge/WEB-INF/lib/

4. Set up CGI on the web

4.1. Go to Tomcat directry
Open Finder and go to your tomcat directory, such as /usr/local/apache-tomcat-{your version}/.
4.2. Edit conf/web.xml file
Open conf/web.xml file on any text editer and comment out for and tags.
If you have any problem, here is the Tomcat site that guide you how to set up CGI more detail.

5. Change php.ini

5.1. Go to PHP folder
Go to PHP directory, such as /opt/local/etc/php53/.
5.2. Edit php.ini file
Open php.ini file on text editer and add following line.

allow_url_include = On

6. Restart Tomcat

If you have not set up Tomcat on your local machine, here is II. How to install Tomcat.

/Library/Tomcat/bin/startup.sh
/Library/Tomcat/bin/shutdown.sh

7. Check the result

Go to http://localhost:8080/JavaBridge/mytest.php and you will see your jar file is executed.
