Subject Re: Odd error
Date Sat, 04 Feb 2012 16:40:55 GMT
Here is more research on my "odd error".  

Production Server Env
	Tomcat, linux, MySQL 5.1, Java 1.6
	I only have control of tomcat config files & start/stop operations
	**** I am using a *temp* configuration for installation and only have an IP which I aliased
to "" in my hosts file (a standard trick)

Symptoms & Research:
It appears that tomcat has logged a Cayenne configuration exception

	Caused by: org.apache.cayenne.ConfigurationException: [v.3.0.1 Aug 25 2010 19:42:04] Can't
open config file URL: jndi:/

Which seems to be accurate because that is not were I put the cayenne.xml file.  Here is my
web.xml entry for the app

	<!-- Cayenne ORM -->

1. I have no understanding of why Cayenne would be looking for the xml file in a path that
included "store". Could this be a result of it getting confused by the alias ""?
2. I have a demo working on the same webhost, but as a subdomain. It is using, I believe,
the identical web.xml excerpt.  This same web.xml file is working on my development server.
 Is there a way to configure cayenne or the temp installation to make this work correctly
3. Or, am I completely on the wrong track? :)

it this error shows up mostly when I am adding the parent to which it is referring, however,
it also has just shown up at random when I make a simple query via cayenne.
