[Php-java-bridge-users] Problem with custom servlet

[<php...@li...>]

Hi, 

I'm a beginner with JavaBridge. I'm executing this example (custom
servlet):
 http://php-java-bridge.sourceforge.net/pjb/servlet-programming.php

Well. When I run the servlet, this runs ok and it don't generate errors,
but  when I run this php script: 

<?php
  define("JAVA_HOSTS", "localhost:8080");
  define("JAVA_SERVLET", "/MyWebApp/Hello");
  require_once("Java.inc");

  echo java_context()->getServlet()->hello();
?>

the script generates this error: 

HTTP Status 500  
The server encountered an internal error () that prevented it from
fulfilling this request 
java.lang.NullPointerException
	php.java.servlet.RemoteHttpServletCont in /var/www/Java.inc on line 869

I don't understand because it generates this errors, any ideas ?.

Rober.
