Update:

I tested this with Jasper Reports, and it is working really nice. It will allow you to Extend Java classes with PHP or just use Java class lik it was PHP.

use java\lang\String as JString;
require_once("javabridge/java/Java.inc");

class String extends JString {
    function toString () {
        return "hello " . parent::toString();
    }
}
$str = new String("Java");
echo $str->toString();

or

$temp = new Java('java.sql.Timestamp');
$javaObject = $temp->valueOf('2007-12-31 0:0:0');


$params = new Java("java.util.HashMap");
$params->put("text", "This is a test string");
$params->put("date",$javaObject);
