loading another datadomain
Hello.
My web application has a single DataDomain. This application are
sometimes deployed with a second application (as a boundled jar-file
in the same classloader) that I am porting over to cayenne. As the
first application has to work without the second app loaded, my main
cayenne.xml has only the first domain and map-file.
During startup of the main application, I want to load the second
domain and map if it is pressent. Is that possible? How?

Yeah, you would want to have both maps in a single DD (otherwise
you'll have to maintain two DataContexts for the same user). If
cdeploy Ant task is too cumbersome to use (i.e. you want runtime
detection), you can load a second map via the API.
The easiest way to do this is using the trick Michael referred to -
rename the second cayenne.xml to something else, then load it in a
separate temporary Configuration instance [new DefaultConfiguration
("my-cayenne.xml")]), and then grab a DataNode from that separate
stack and attach it to the main stack (DataDomain.addNode(..)).

If it is easier, I guess using a single DataDomain for both of the
DataMaps should be possible. Each of the DataMaps will have a
separate DataNode. I still wonder how those can be loaded if present.
