MXINFO question

Hello,

I've just created my first MXINFO file, but the descriptions I put in 
don't appear in the management console of MX4J. Apparently the file 
wasn't evaluated, but I don't see any error message in phoenix.log. Here 
are the files I have:

MyApp - an empty interface class (no methods or constructors)
MyAppMBean - contains some interface definitions for JMX
MyAppImpl - contains the implementations of the MyAppMBean interfaces 
and implements MyApp
MyAppMBean.mxinfo - my MXINFO file

Here's my MyAppMBean file:

public interface MyAppMBean {
    public String deleteObject(String id);
    public String getStatus();
    public void resume();
    public void pause();
    }

Here's what I have in the MXINFO file:

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE mxinfo PUBLIC "-//PHOENIX/Mx Info DTD Version 1.0//EN"

"http://jakarta.apache.org/avalon/dtds/phoenix/mxinfo_1_0.dtd";>

<mxinfo>

    <topic name="MyApp">

      <!-- attributes -->
      <attribute
        name="status"
        description="Status of MyApp"
        isWriteable="no"
        type="java.lang.String"
      />

      <!-- operations -->
      <operation
        name="deleteObject"
        description="Deletes an Object"
        type="java.lang.String"
      >
        <param
          name="instance"
          description="ID of Object to be deleted"
          type="java.lang.String"
        />
      </operation>

    </topic>

</mxinfo>

I was expecting that the descriptions I put in should appear in the 
MX4J-generated MBean web page, but they don't. I can think of two 
possible mistakes I made (although the docs don't forbid them):

1. I didn't define all the methods from the interfaces in MyAppMBean in 
the MXINFO file, because I only need descriptions for a few.

2. I should have called the MXINFO file MyAppImpl.mxinfo

Any ideas on how to debug this?
