Java EE (Java Enterprise Edition) General Discussion

I want to try one AJAX example with DWR, so I refered one tutorial and according to taht I have downloaded dwr.jar and placed it in web-inf/lib and created

dwr.xml

  <!DOCTYPE dwr PUBLIC
    "-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN"
    "http://www.getahead.ltd.uk/dwr/dwr10.dtd">

<dwr>
  <allow>
    <create creator="new" javascript="JDate">
      <param name="class" value="java.util.Date"/>
    </create>
    <create creator="new" javascript="Demo">
      <param name="class" value="your.java.Bean"/>
    </create>
  </allow>
</dwr>[ /code]

and my web.xml is 

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>


<servlet>
<servlet-name>guestDBServlet</servlet-name>
<servlet-class>guestDBServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>guestDBServlet</servlet-name>
<url-pattern>/guestDBServlet</url-pattern>
</servlet-mapping>

<servlet>
  <servlet-name>dwr-invoker</servlet-name>
  <display-name>DWR Servlet</display-name>
  <servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
  <init-param>
     <param-name>debug</param-name>
     <param-value>true</param-value>
  </init-param>
</servlet>

<servlet-mapping>
  <servlet-name>dwr-invoker</servlet-name>
  <url-pattern>/dwr/*</url-pattern>
</servlet-mapping>


<resource-ref>
        <description>DB Connection</description>
        <res-ref-name>jdbc/MySQL</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
    </resource-ref>


</web-app>

Now the tutorial was saying  got to 
http://localhost:8080/[YOUR-WEBAPP]/dwr/ 
You should see a page showing you the classes that you've selected

When I tried got message Project/dwr is not available

Anybody can  advice ?
