[appfuse-user] DWR help

[Martin Ravell]

Hi,

I’m having a play with Appfuse 2 and DWR but without much luck and was
wondering if someone could help.

I thought I’d start with a simple demo and see if I could get it to work
within the confines of a clean Appfuse project. The demo is from
http://getahead.org/dwr/examples/text.


My dwr.xml looks like this:


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC
    "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
    "http://getahead.org/dwr/dwr20.dtd";>

<dwr>
  <allow>
    <create creator="new" javascript="Demo">
      <param name="class" value="com.rave.ChessChat.Demo"/>
    </create>
  </allow>
</dwr>


The JSP page looks like this:

<%@ include file="/common/taglibs.jsp"%>

<script type='text/javascript' src='/dwr/engine.js'></script>
<script type='text/javascript' src='/dwr/util.js'></script>
<script type='text/javascript' src='/dwr/interface/Demo.js'></script>

<script type='text/javascript'>

function update() {
  var name = dwr.util.getValue("demoName");
  Demo.sayHello(name, function(data) {
    dwr.util.setValue("demoReply", data);
  });
}

</script>

<p>
  Name:
  <input type="text" id="demoName"/>
  <input value="Send" type="button" onclick="update()"/>
  <br/>
  Reply: <span id="demoReply"></span>
</p>


The Demo.java looks like this:

package com.rave.ChessChat;

public class Demo
{
  public String sayHello(String name)
  {
    System.out.println("Bolocks");
    return "Hello, " + name;
  }
}



I can URL the page and it displays OK but nothing happens when I hit the
Send button. Any ideas on what more I need to get this to go?


Regards
Marty
