Problem in logging site analysis event from serveResource method

The Logging custom business event using Site Analysis entry explains how you can use the com.ibm.portal.portlet.service.siteanalyzer.PortletSiteAnalyzerLoggingServiceHome for logging custom business event. As per WPS documentation we should be able to use this service from serveResource() method also but when i tried logging a sample event in the serverResource i get exception.

This is the code that i used

public void serveResource(ResourceRequest request, ResourceResponse response)
throws PortletException, IOException {
response.setContentType("text/html");
response.getWriter().println(
"Hello from SiteAnalyticsDebugPortlet.serveResource()");
PortletSiteAnalyzerLogger logger = portletSiteAnalyzerLoggingServiceHome
.getLogger(request, response);
if (logger.isLogging()) {
logger.log("Sample serveResource event");
}



This is the exception that i am getting. I might have to open a PMR with IBM for this
