				}
				catch(JMSException e)

					logger.debug("Failed to close - ",e);

			}	
		}
		logger.debug("sendMessageToQueue end");
	}



the problem - 

the line -> 			connectionFactory = (ConnectionFactory)
jndiContext.lookup("jms/ConnectionFactory");

is causing

javax.naming.NamingException: Cannot create resource instance
        at
org.apache.naming.factory.ResourceFactory.getObjectInstance(ResourceF
actory.java:143)


I have spent roughly 10 hours on this now. I have searched all of Google,
Nabble, activemq/tomcat.apache.org ... all I can find is people more or less
asking "what have I done wrong" but I have not found anyone offering a
solution. The best documentation I can find on apache.org contains the
phrase  "This is completely untested but should work" ... and it does not.
At one point I thought I was nearing success by doing the "Look Inside this
Book" on Amazon.com looking at "Tomcat: The Definitive Guide (Paperback)"
but ultimately that did not work either. My Junit tests (in Eclipse using
jndi.properties) all work with no problem. When I try doing this within
tomcat w/ web.xml and context.xml it fails horribly.

Any input would be desperately appreciated.
