How to communicate with java code in PHP

Question

G' Day,

I have a requirement, where need to invoke java function in PHP script. I have been gone through PHP JAVA Bridge concept but not able to call from PHP script. May be my Process was wrong. Please find the below process what i have been implemented.

1. step -1 C:\xampp\htdocs\tomcat\webapp Need to pest JavaBridge.war in this webapp.

2. step - 2 Extract this (JavaBridge.war) file. then go to JavaBridge/WEB-INF/lib/ and copy below three files and pest into C:\xampp\htdocs\tomcat\webapp\bin

   php-script.jar php-servlet.jar servlet_api.jar

3. Step -3 Edit the Tomcat conf/web.xml. Add the following 9 lines marked with a +:

       + <listener><listener-class>php.java.servlet.ContextLoaderListener</listener-class></listener>
       + <servlet><servlet-name>PhpJavaServlet</servlet-name><servlet-class>php.java.servlet.PhpJavaServlet</servlet-class>
       + </servlet>
       + <servlet><servlet-name>PhpCGIServlet</servlet-name><servlet-class>php.java.servlet.fastcgi.FastCGIServlet</servlet-class>
       + <init-param><param-name>prefer_system_php_exec</param-name><param-value>On</param-value></init-param>
       + <init-param><param-name>php_include_java</param-name><param-value>Off</param-value></init-param>
       + </servlet>
       + <servlet-mapping><servlet-name>PhpJavaServlet</servlet-name><url-pattern>*.phpjavabridge</url-pattern>
   

   + PhpCGIServlet*.php ...
   

4. step - 4 Start Tomcat again. Now you can add PHP scripts to tomcat.

5. step - 5 Add a PHP test file

   <?php require_once("java/Java.inc");
   echo java("java.lang.System")->getProperties(); ?> 
   

   to some web context, for example "examples", and browse to http://yourHost.com:8080/examples/test.php.

Its working fine but when i am run this file in htdocs (http://yourHost.com/test.php) its throwing exceptions.

Please suggest me if i have been implemented wrong process or let me know if any new interface will work through this problem.

I do appreciate for Adv help.

I think you need to set your php.ini to allow url includes. The docs.
