run no_xml_example
Hello,
I want to run the no_xml_example of A.Rothe:
https://cwiki.apache.org/CAY/no-xml-example.html.
But I get the following Exceptions:
org.apache.cayenne.CayenneRuntimeException: [v.3.1M3 Sep 13 2011 19:17:16]

Yes, I think I should do it on my own.
Now I configure Cayenne like in the post:
http://cayenne.195.n3.nabble.com/How-to-configure-Cayenne-and-map-generic-object-programmatically-from-scratch-without-using-of-XML-td3506305.html.
I don't understand where and how to implement DataSourceFactory and
Provider<DataDomain>.
best regards

Not sure about no-xml-example. Haven't looked at this code. But maybe you can do it the other way around - decide what you need to do in your app, and then figure out how to do that in Cayenne. And use this list to get advice if you get stuck.
