Installing Php/java Bridge

If you are using the RedHat Linux system (RedHat Enterprise or Fedora), you can download the 32-bit RPM package from the home page and enter rpm-i php-java-bridge-v.x.y-z-i386.rpm to install it. If you are using a 64-bit system and a 64-bit virtual machine, you need to install a 64-bit RPM package. Other systems look at the introduction below.

(1) Before installing Php/java Bridge, you need to make sure that you have installed:
Java1.4 or later,
gcc3.2 or later,
apache1.3 or later,
autoconf2.57 or later, done
Libtool 1.4.3 or later, done
automake1.6.3 or later,
GNU make Done
php4.3.2 or later

You can use the command java-version, gcc--version, apachectl-version, Libtool--version, automake--version, make null--version, AutoCo NF--version and Php-config. Version to determine the versions of these packages.

(2) Download the source code for Php/java Bridge
Http://www.sourceforge.net/projects/php-java-bridge

(3)
Decompression: Cat php-java-bridge_v.x.y.tar.bz2 | BUNZIP2 | Tar XF?

(4)

Execute the command in the unzipped directory php-java-bridge-v.x.y:

Phpize &&/configure--disable-servlet--with-java=/opt/ibmjava2-14 && make cflags= "-m32"

Generates a module for a 32-bit JVM.

(5) Install the generated module
Su-c ' Make install '

(6) Php/java Bridge can be run as the sub-component of the Web server, Add the following line to the php.ini, or write the line to a file Java.ini, and then copy the Java.ini to the directory containing the description of the PHP module, such as/etc/php.d/.

Extension = java.so
[Java]

(7) Restart Apache server:/www/apache/bin/apachectl restart

(8) You are now ready to test your Web installation. Copy the test.php to the site root directory (such as/var/www/html), accessed through the browser. You can see that the bridge module is active and running. Bridge will start as the server starts.

test.php

Phpinfo ();

print "\ n";

$v = new Java ("Java.lang.System");

$arr = $v->getproperties ();

foreach ($arr as $key = = $value) {

Print $key. "." $value. "
\ n ";

}

?>

Installation under the Windows platform:

1. Unzip php-java-bridge_2.0.4-win32-php5.zip, copy all files to C:\php

2. Double-click C:\php5\JavaBridge.jar or execute java-jar at the command line Javabridge.jar

3. php-cgi test.php >result.html (test.php source see above example)

4. Open result.html with your browser to see the results of the run

The segment tester first outputs all the options for the PHP environment, and then creates a new Java object and returns information about it.

Here, we are free to communicate with the Java object and implement the bridging between PHP and Java.

5. Next Modify your PHP.ini (C:\Windows\php.ini), put the semicolon before the Extension=php_java.dll;

Note that PHP also comes with a php_java.dll, which is located under C:\php\extensions, and is different from what Php-java-bridge offers. To avoid errors, be careful to set the Extension_dir in PHP.ini, the default Extension_dir = "./" to the C:\php directory.
