No class by name: AjaxUtils

J've just installed JForum 2.1.6 and, in the admin pages, when I click on "Configurations" in "Forum Admin" I see the page and get the following exception.

What's wrong and how do I solve it?

Rafael, I've checkout the CVS today to check if this error happens there too.

I confirm that it happens in the lastest version of the code.
And I haven't mess with the configuration. It happens "out of the box".

hhm.. problem related to jetty? Are you able to just test it with Tomcat?

Thanks

In fact the pb seems to load the dwr-jforum.xml...

I think the parameter of the servlet DWRServlet was not correctly pass with some application server.

I modify the web.xml as follow

<!-- AJAX -->
<servlet>
<servlet-name>dwr-invoker</servlet-name> <servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
<!-- <br /> <init-param> <br /> <param-name>configJForum</param-name> <br /> <param-value>WEB-INF/dwr-jforum.xml</param-value> <br /> </init-param> <br /> -->
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
</servlet>

I copy dwr-jforum.xml to dwr.xml and now it's working in Ias 10gR3...

May this help some one of you...

edit your web.xml
change .. from
<param-value>WEB-INF/dwr-jforum.xml</param-value>
to
<param-value>/WEB-INF/dwr-jforum.xml</param-value>

This fixed my AjaxUtils class problem. Now I am getting the following logs... Any ideas? I am running 2.1.7 on Jetty5.

Ran into this as well, so I'll post this just for reference.

You should be able to fix all errors from DWR by changing the content of your dwl-jforum.xml to the following:

<?xml version="1.0" encoding="UTF-8"?>
<!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="AjaxUtils">
			<param name="class" value="net.jforum.util.ajax.AjaxUtils"/>
		</create>
		<convert converter="bean" match="net.jforum.entities.*"/>
	</allow>
</dwr>

Works for DWL version 1.1 supplied with JForum 2.1.7.


Regards,
Martin
