Environment (JDeveloper, ADF BC, ADF Faces)
When you work with large application which contains more than one Model/one ViewController projects, you need to set the project dependency between the model and the view controller project., failing to do this you may face this exception.
oracle.jbo.ConfigException: JBO-33001: Configuration file /model/common/bc4j.xcfg is not found in the classpath.
To solve the problem, double click the viewController project to open project properties dialog, and select the the Dependencies node and click the Edit Dependecies icon to add a dependency on the build output path or on one or more deployment archives.
Hope this will help someone faced the same problem.
