Jeff Pierson commented on CAY-785:
----------------------------------
Today I got the trunk built on my machine and tried to debug this problem.
With my limited knowledge of Cayenne internals, here is what I think is
happening. The Modeler application, when opening a Cayenne.xml file calls
ProjectAction.buildProjectApplication() which makes a new ProjectConfiguration
object. ProjectConfiguration overrides the getDataSourceFactory() method of
Configuration and always returns a ProjectDataSourceFactory which extends
DriverDataSourceFactory. When the RuntimeLoadDelegate.shouldLoadDataNode()
attempts to load the datasource it calls getDataSourceFactory() and uses the
ProjectDataSourceFactory instead of the DBCPDataSourceFactory that was passed
in. It tries to parse the dbcp.properties file as if it were a driver.xml
file. If you delete or rename the dbcp.properties file, the modeler will go
ahead and load the project. I was hoping this was a simple fix and I could
just submit a patch but I don't think that is the case. I also think this is
more than a minor bug. It seems to me that the Modeler will always fail to
load any project using dbcp if the dbcp.properties file exists, which is the
normal case.
