Forgot to add the exception for the 5.0 configuration is:

OK found the solution:

I added a ServerInvokerServlet to the invoker:

in deploy/http-invoker.sar/META-INF/jboss-service.xml

Add:

<mbean code="org.jboss.remoting.transport.Connector"
name="jboss.remoting:service=connector,transport=servlet"
    display-name="Servlet transport Connector">
    <attribute
name="InvokerLocator">servlet://${jboss.bind.address}:8080/invoker/ServerInvokerServlet</attribute>
    <attribute name="Configuration">
      <handlers>
        <handler
subsystem="AOP">org.jboss.aspects.remoting.AOPRemotingInvocationHandler</handler>
      </handlers>
    </attribute>
  </mbean>

In deploy/http-invoker.sar/WEB-INF/web.xml

Add:

<servlet>
        <servlet-name>ServerInvokerServlet</servlet-name>
        <description>The ServerInvokerServlet receives requests via HTTP
           protocol from within a web container and passes it onto the
           ServletServerInvoker for processing.
        </description>
        <servlet-class>org.jboss.remoting.transport.servlet.web.ServerInvokerServlet</servlet-class>
        <init-param>
            <param-name>invokerName</param-name>
            <param-value>jboss.remoting:service=invoker,transport=servlet</param-value>
            <description>The servlet server invoker</description>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>ServerInvokerServlet</servlet-name>
        <url-pattern>/ServerInvokerServlet/*</url-pattern>
    </servlet-mapping>

Finally change the url in the jboss.xml file to:

<client-bind-url><![CDATA[http://${jboss.bind.address}:8080/invoker/ServerInvokerServlet?timeout=300000&invokerDestructionDelay=300000]]></client-bind-url>

Missed one - add deploy/http-invoker.sar/META-INF/jboss-service.xml -

<mbean code="org.jboss.remoting.transport.Connector"
      name="jboss.remoting:service=Connector,transport=Servlet"
      display-name="Servlet transport Connector">
      <depends>jboss.aop:service=AspectDeployer</depends>
      <attribute name="InvokerLocator">
         servlet://${jboss.bind.address}:8080/servlet-invoker/ServerInvokerServlet
      </attribute>
     
      <attribute name="Configuration">
         <handlers>
