How to install php-java bridge on plesk centos  ?
If you want to install php-java bridge then you need to follow the steps.

For java :
Please check JAVA is installed or not on your server.
[root@server]# which java
[root@server]# ll /usr/bin/java
lrwxrwxrwx 1 root root 22 Mar 12 20:00 /usr/bin/java -> /etc/alternatives/java
[root@server]# ll /etc/alternatives/java
lrwxrwxrwx 1 root root 39 Mar 12 20:00 /etc/alternatives/java -> /usr/lib/jvm/jre-1.6.0-openjdk/bin/java

Means java is installed into the folder “/usr/lib/jvm/jre-1.6.0-openjdk” so export the java home

[root@server]# export JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk

If java is not installed then you can installed it by using following commands
[root@server]# yum install java
you can install it manually by using following steps
Download j2sdk-1.4.2 from Sun Download center Here I have used j2sdk-1_4_2_18-linux-i586-rpm.bin which will install j2sdk using RPMS and set the Path of JAVA_HOME automatically
[root@server]# chmod +x j2sdk-1_4_2_09-linux-i586.bin
[root@server]# ./j2sdk-1_4_2_09-linux-i586.bin

Now Check if Java is installed on the server using command java -version
[root@server]# java -version
java version “1.6.0_07?
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing

Installation of PHP / Java bridge
[root@server]# cd /usr/src
[root@server]# wget
[root@server]# rpm2cpio php-java-bridge-4.1.8-1.src.rpm | cpio -ivd
[root@server]# tar xzf php-java-bridge_4.1.8.tar.gz
[root@server]# cd php-java-bridge-4.1.8
[root@server]# phpize
[root@server]# ./configure --with-java=$JAVA_HOME
[root@server]# make
[root@server]# make install
Add the following lines in php.ini file
vi /etc/php.ini
java.java_home = "/usr/lib/jvm/java-1.6.0-openjdk/bin" = "/usr/lib/jvm/java-1.6.0-openjdk/bin/java"
java.class.path = "/usr/local/src/JavaBridge.jar"
; NOT SURE about the next line, for me works
java.library = "/usr/lib/jvm/java-1.6.0-openjdk-"
java.library.path = "/usr/lib/php/modules"
java.log_level = 2

The check php-java-bridge is properly installed or not
[root@server]#  php -i | grep java
Output is as follows
java support => Enabled
java bridge => 4.1.8
java.java_home => /usr/lib/jvm/java-1.6.0-openjdk/bin => /usr/lib/jvm/java-1.6.0-openjdk/bin/java
java.log_file => <stderr>
java.log_level => 2
java.security_policy => Off
java command => JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk/bin LD_LIBRARY_PATH=/usr/lib/php/modules: /usr/lib/php/modules/RunJavaBridge /usr/lib/jvm/java-1.6.0-openjdk/bin/java -Djava.library.path=/usr/lib/php/modules -Djava.class.path=/usr/lib/php/modules/JavaBridge.jar -Djava.awt.headless=true LOCAL:9268 2
java status => running
java server => 9268

For testing =
[root@server]#cd /var/www/vhosts/default/htdocs/
[root@server]# mkdir java
[root@server]# locate
[root@server]# cp /usr/local/src/META-INF/java/  /var/www/vhosts/default/htdocs/java

Then create file Java.php in /var/www/vhosts/default/htdocs/java and add the following code in it.
[root@server]# cd /var/www/vhosts/default/htdocs/java
[root@server]# vi Java.php
$session = java_session();
$system = new Java('java.lang.System');
// créer une instance de la classe Java java.lang.System dans PHP
// accéder aux propriétés
echo 'Java version=' . $system->getProperty('java.version') . ' <br />';
echo 'Java vendor=' . $system->getProperty('java.vendor') . '<br />';
echo 'OS=' . $system->getProperty('') . ' ' .
$system->getProperty('os.version') . ' on ' .
$system->getProperty('os.arch') . '<br />';
// Exemple avec java.util.Date
$formater = new Java('java.text.SimpleDateFormat',
"EEEE, MMMM dd, yyyy 'at' h:mm:ss a zzzz");
echo $formater->format(new Java('java.util.Date'));

Then access the URL
If the URL shows the output of code then the PHP-Java bridge is properly installed on your server
If you are getting any error then please ask me on this thread

    1. Hello Rohit,
      Thanks for the comments. Please check the code
      require_once("java/"); in Java.php file and correct the path or name of file. As per above code first locate the file and then create the folder “java” in the same folder in which “java.php” file is present then copy the file in “java” folder.
      If you are still facing same error then check the server logs.
      If JavaBridge.jar is not present then donload this file by using the URL ” “. in /usr/local/src folder.

      yum install php-devel
      after that run phpize on your server
