How to dynamically pass parameters in web.xml using weblogic 10.3.x?

 I am trying to pass a JVM parameter for a variable configured in web.xml as a context-parameter using a -D notation when starting weblogic server. I have already tryied this same configuration using Tomcat 7 and it works as expected, but it DOES NOT work in weblogic server 10.3.3, any clues?

web.xml

        <?xml version="1.0" encoding="UTF-8"?>

    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd
