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.
