PHP - JAVA BRIDGE

1) Download PHP-Java bridge here.

2) Extract the Zip there you can find JavaBridge.war extract that too.

3) You can find JavaBridge.jar here [JavaBridge.war\WEB-INF\lib\]. Copy that file to your lib\php\modules [LINUX]. For windows xampp/php/ext.

4) Run this command 

java -jar /usr/lib/php/modules/JavaBridge.jar HTTP_LOCAL:8088 3 JavaBridge.log

5) Make sure the path in above command is matches your path where you have placed the JavaBridge.jar

6)Make sure port 8088 is not listening some other service like tomcat.

7)Extract JavaBridge.jar and copy the java folder which is present in JavaBridge.jar\META-INF\  to wherever you want.  [Don't change the existing one which is present in your ext or module folder] 

8) Then run the below. It will display the info and java bridge version and some other properties.

9) require_once("java/Java.inc"); [Present in the below coding]. You need to change the path as per your requirement.
