Have you tried
<head>
<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>
</head>

No, unfortunately, I don't know what the problem could be. You might
try debugging with Firebug in Firefox.

Hi Matt,
The /dwr page shows my Demo object and lets me execute it. A
System.out.println tells me that DWR is executing the method call on Demo
but it does not appear as if any value is being passed back to the page.
This would be consistent with the behaviour of my jsp page.
Any ideas?
Regards
Marty

If you go to http://localhost:8080/dwr - can you execute your class's
JavaScript from that page?

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
