Thanks for your super quick response Andrus. I'm heavily reliant on
Netbeans (AKA lazy programmer ;-) ) so I typically avoid delving into
Ant configuration. I like my IDE to take care of the details. I just
learned how to add a classpath to a Netbeans project to get what I want
below!! How sad is that?

It has this little piece there: "Location is a '/'-separated path (same path
separator is used on UNIX and Windows) that is resolved relative to the application
classpath". But I guess we can emphasize it better.
Ideally I'd like to place my cayenne configuration files into the folder
WEB-INF/DBConfig_CayenneV3.1 using the simplest possible method so that it's
clear to any future developers of my project to understand exactly what these
files are used for.
First, let's maybe rename it to "DBConfig_CayenneV3_1" (Just in case, as "." can mean
other things in Java). Now since you are in control of the app structure, I suggest you just put them under
"WEB-INF/classes/DBConfig_CayenneV3_1" or a similar folder. But this is in a resulting .war. In
your *source* you would simply put it in a folder that is packaged to WEB-INF/classes during the .war
assembly. And your build tool (Maven, Ant, etc) will ensure it is in the right place in archive.
IMO placing it in "src/main/resources" (if you are using Maven) or to your Java
sources folder will make it very clear to developers. (in a DBConfig_CayenneV3_1
subpackage if you like).
Sticking to locations that end up on CLASSPATH one way or the other will ensure
you don't need a custom CayenneFilter. But of course you can write one to load
from WEB-INF too, which requires some, but very minimal DI understanding.

I'm trying to migrate to Cayenne 3.1 and I had the same problem trying to
figure out this problem until I found this thread topic. I'm trying to map the

from the documentation. (BTW, could the documentation be updated to reflect
the expected location of the cayenne configuration files?)
https://cayenne.apache.org/docs/3.1/cayenne-guide/starting-cayenne.html
"When started by the web container, it creates a instance of ServerRuntime and stores it in the ServletContext.
Note that the name of Cayenne XML project file is derived from the "filter-name". In the example above
CayenneFilter will look for an XML file "cayenne-project.xml". This can be overridden with
"configuration-location" init parameter."
I'm using tomcat (and I'm certainly not a power user and I don't want to dive
into DI) so I'm not clear exactly which init parameter this is referencing.

WEB-INF/DBConfig_CayenneV3.1 using the simplest possible method so that it's

<servlet>

<param-name>configuration-location</param-name>
<param-value>/WEB-INF/DBConfig_CayenneV3.1</param-value>
</init-param>
...
</servlet>
Thanks,

Great! Yeah, removing support for WEB-INF as a config location was an
intentional step. Using CLASSPATH to locate resources is the most portable
approach that works in any Java environment, not just web apps.
And of course for those who are used to WEB-INF/, it is always easy to write
your own bootstrap code based on CayenneFilter ideas.

Hi Andrus,
Thank you!
......
"cayenne-shopperDomain.xml" was located in WEB-INF. Changed my ant build
script to move "cayenne-shopperDomain.xml" (and the other associated cayenne
configuration files) to WEB-INF/classes. That was it. Doh! I did a Homer
Simpson :) I overlooked the obvious :). Thank so much for your patience.
.....
FYI
.....
Had been using Cayenne v3.0.1 and v.3.0.2 with Tomcat (on various projects).
Never to had to move the cayenne configuration files from "WEB-INF" to
"WEB-INF/classes" before. Thus, my confusion over the obvious.
......
In general, kudos to all the Cayenne contributors. I find Cayenne a joy to
work with.
......
The Cayenne Modeler v3.1M3 graphing is a great feature.
.....
Thank you so much for the help.
