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 "om28.com" 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:/om28.com/store/WEB-INF/config/cayenne-files/cayenne.xml
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 -->
<context-param>
<param-name>cayenne.configuration.path</param-name>
<param-value>/WEB-INF/config/cayenne-files</param-value>
</context-param>
<filter>
<filter-name>CayenneFilter</filter-name>
<filter-class>org.apache.cayenne.conf.WebApplicationContextFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CayenneFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Questions:
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 "om28.com"?
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? :)
