trouble getting link to user-defined java class from php using php-javaBridge

We need to call a user defined java function within php code,so javaBridge connection is needed.

we have done the php-javabridge-configuration and it is working fine. http://phprambabu.blogspot.in/2016/04/php-javabridge-configuration.html

To connect php with java class, we are running the java class from eclipse on tomcat server, HTTP port:8086 and mentioning the same port number in java.inc file, and its path is added in php file as "required_once(Java.inc)".

-> this shows error in Java.inc file but changes made in Java.inc seems correct according to other resources found on internet and stackoverflow.

changes in Java.inc

define ("JAVA_HOSTS", "localhost:8086");

...

if(!defined("JAVA_HOSTS")) {
    if(!java_defineHostFromInitialQuery(java_get_base())) {
        if ($java_ini=get_cfg_var("java.hosts")) define("JAVA_HOSTS",$java_ini);
        else define("JAVA_HOSTS","127.0.0.1:8086");
    }
}

php file content snippet

function createBridge() {
    $demo = new java("main.bridge");
    echo 'New Bridge instance created';
    $demo->fn();
    return $demo;
}

Here, running java src folder contains -> "main" folder contains -> "bridge.java" -> fn() function

if mentioned changes are done in java.inc, Fatal error occurs:

Fatal error: HTTP status 403, Access to the specified resource has been forbidden. Apache Tomcat/7.0.72 in C:\xampp\htdocs\JavaBridge\java\Java.inc on line 869

Line 869 refers to 3rd line of below snippet:

function dieWithBrokenConnection($msg) {
    unset($this->protocol->client->protocol);
    trigger_error ($msg?$msg:"unknown error: please see back end log for details",E_USER_ERROR);
}

And we are using Xampp for local server. Please let us know if I'm doing something wrong in between or any other useful stuff that can help us out.
