soluble-japha-pjb62-compat

Introduction

*** Work in progress ***

Historically the PHP/Java bridge client didn't support namespaces.

Install this package if you have existing code relying on legacy php-java-bridge and don't want to refactor to the newer implementation provided by soluble/japha.

Features

Make soluble-japha compatible with the procedural phpjavabridge legacy api

Requirements

PHP 5.5+, 7.0 or HHVM >= 3.2.
The PHPJavaBridge server running

Installation

PHP installation (client)

Through composer.
```
$ composer require "soluble/japha-pjb62-compat"
```
Most modern frameworks will include Composer out of the box, but ensure the following file is included:
```
<?php
// include the Composer autoloader
require 'vendor/autoload.php';
```
PHP-Java-bridge server

Refer to the latest documentation provided in the soluble-japha project.

Or as quick install guide use the standalone server :
```
$ mkdir -p /my/path/pjbserver-tools
$ cd /my/path/pjbserver-tools
$ composer create-project --no-dev --prefer-dist "belgattitude/pjbserver-tools"
$ ./bin/pjbserver-tools pjbserver:start -vvv ./config/pjbserver.config.php.dist
```
The server will start on default port 8089. If you like to change it, create a local copy of ./config/pjbserver.config.php.dist and refer it in the above command.

Use the commands pjbserver:stop, pjbserver:restart, pjbserver:status to control or query the server status.

For production the recommended way is to deploy the JavaBridge servlet into a J2EE compatible server (Tomcat,...). Have a look to the complete java server installation documentation.

Examples

Connection example

Configure your bridge adapter with the correct driver (currently only Pjb62 is supported) and the PHP-Java-bridge server address.

<?php

use Soluble\Japha\Bridge\Adapter as BridgeAdapter;

$ba = new BridgeAdapter([
    'driver' => 'Pjb62',
    'servlet_address' => 'localhost:8089/servlet.phpjavabridge'
]);

This replace the include('xxx/Java.inc) used in previous versions.

Basic Java usage

With legacy mode enabled you can use the java* function directly

<?php

use Soluble\Japha\Bridge\Adapter as BridgeAdapter;

$ba = new BridgeAdapter([
    'driver' => 'Pjb62',
    'servlet_address' => 'localhost:8083/servlet.phpjavabridge'
]);

$bigint = new Java("java.math.BigInteger", 1);
$system = java_class('java.lang.System);

java_instanceof($bigint, 'java.math.BigInteger'); // -> true
java_inspect($bigint); 
java_values($bigint);
//java_invoke();

API

Refactor constants

Constant	Example
`JAVA_HOSTS`	`define("JAVA_HOSTS", "127.0.0.1:8787")`
`JAVA_SERVLET`	`define("JAVA_SERVLET", "/MyWebApp/servlet.phpjavabridge")`
`JAVA_PREFER_VALUES`	`define("JAVA_PREFER_VALUES", 1)`
`JAVA_LOG_LEVEL`	`define("JAVA_LOG_LEVEL", null)`
`JAVA_SEND_SIZE`	`define("JAVA_SEND_SIZE", 8192)`
`JAVA_RECV_SIZE`	`define("JAVA_RECV_SIZE", 8192)`
`JAVA_DISABLE_AUTOLOAD`	Not applicable anymore - PSR4 ;)

Initialization

Old way	New way
`include(... /Java.inc)`	`$ba = new Bridge\Adapter($option);`

API

The following table maps old and new recommended API.

Legacy	`Bridge\Adapter` ($ba)
`new Java($class, $args=null)` : `Java`	`$ba->java($class, $args=null)` : `Interfaces\JavaObject`
`java_class($class)` : `JavaClass`	`$ba->javaClass($class)` `Interfaces\JavaClass`
`java_instanceof($object, $class)` : `boolean`	`$ba->isInstanceOf($object, $class)` : `boolean`

(under review, soon to be implemented)

Legacy	`Bridge\Adapter` ($ba)
`java_values($object)` : `mixed`	`$ba->getValues($object)` : `mixed`
`java_invoke($object, $method, $args=null)` : `mixed	null`
`java_inspect($object)` : `string`	`$ba->debug()->inspect($object)` : `string`
`getLastException` : `Exception`	`$ba->debug()->getLastException()` : `Exception`
`clearLastException`	`$ba->debug()->clearLastException()`

function java_is_null($value) function java_is_true($value) function java_is_false($value)

Refactoring guidelines

Keep a step by step approach... you can use both API at the same time.
