Subject Re: Two DataMaps/DataNodes with the same entity/class name
Date Tue, 16 Jun 2009 12:22:38 GMT
Hi Borut, you may want to look at my copying DataMaps example:

It is old (still references "objectstyle" instead of "apache", but
might work fine with minor changes (like changing the package name).
(I haven't tried it on Cayenne 2.x+ yet.)

I was able to use the same classes across different
DataDomains/DataNodes even within the same running application using
this technique.  (I had 7 active database connections to development
(x2), testing (x2), acceptance (x2), and production (x1) databases for
a support program to examine application data internals.)  The trick
is to create your DataContext passing it the correct
DataDomain/DataNode to use and then all is well.  Cayenne handled
everything very smoothly after that -- everything went to the proper
database connection since the DataContext (which was created with the
DataDomain/DataNode to use) does all the queries and the commits.
