If the XML-RPC interface of QueueMetrics is not working, i.e you get no meaningful response, you have to look up on the
catalina.out file in order to detect possible problems.
Xerces not installed With Java 1.5 and Tomcat 5.5, you may encounter the problem as an error string stating
redstone.xmlrpc.XmlRpcException: Could not instantiate XMLReader parser. This means the Xerces XML parser cannot be found.
If this happens, download Xerces from
http://xerces.apache.org/xerces-j/ and put the file called
xercesImpl.jar in your
queuemetrics/WEB-INF/lib. This should solve your problems.
