    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.


    Cayenne Modeler Fails to Open Project

    Key: CAY-785
    URL: https://issues.apache.org/cayenne/browse/CAY-785
    Project: Cayenne
    Issue Type: Bug
    Components: CayenneModeler GUI
    Affects Versions: 2.0 [STABLE]
    Environment: Ubuntu 7.04, JDK 1.5.0_11
    Reporter: Gary Jarrel
    Assignee: Andrus Adamchik
    Priority: Minor
    Attachments: files.tar.gz


    If cayenne.xml contains an entry:

    <map-ref name="katya"/>
    </node>
    Noting the datasource: katya.driver.properties
    The following exception occurs:
