Convergence - problem enabling browser-side caching

Question

I am following the ["Enhancing Browser-Side Caching of Static Files" section of the Convergence Performance Tuning|http://wikis.sun.com/display/CommSuite/Convergence+Performance+Tuning#ConvergencePerformanceTuning-EnhancingBrowserSideCachingofStaticFiles] wiki document.
I installed the class file
-rw-r--r--   1 root     root        2724 Oct  2 08:50 /opt/SUNWappserver/domains/domain1/config/lib/classes/ExpiresFilter.classAnd I added the following to default-web.xml (just below the last </servlet-mapping>)
<filter>
    <filter-name>ExpiresFilter</filter-name>
    <filter-class>iwc.ExpiresFilter</filter-class>
  </filter>
  <filter-mapping>
      <filter-name>ExpiresFilter</filter-name>
      <url-pattern>/iwc_static/js/*</url-pattern>
      <url-pattern>/iwc_static/layout/*</url-pattern>
      <dispatcher>REQUEST</dispatcher>
      <dispatcher>FORWARD</dispatcher>
  </filter-mapping>When I restart glassfish, I get this error in iwc_admin.log
ADMIN: ERROR from com.sun.comms.client.admin.web.util.ConfigHelper  Thread pool-1-thread-4 ipaddress= sessionid= at 09:21:35,355- Error occured while loading the configuration from the file Parsing Error

I'm guessing that it isn't loading the class correctly. Any ideas?

What version of Convergence are you using (./iwcadmin -V)?
I tried the steps with Convergence patch 10 (update 3) and Glassfish 2.1 (on Redhat Linux) and it worked fine -- I see "Expires" and "Cache-Control" headers for Convergence file requests.
I installed the class file
-rw-r--r--   1 root     root        2724 Oct  2 08:50 /opt/SUNWappserver/domains/domain1/config/lib/classes/ExpiresFilter.class
The class file should be in:
/opt/SUNWappserver/domains/domain1/lib/classes/iwc/Regards,
