Solution:
In the Model project JDeveloper has created files related to ViewController (Web Content/WEB_INF folder with faces-config.xml, trinidad-config.xml  and web.xml). If you use a SubVersioning System, it is easy to check because they ll newly created and not added to SVN.
 

Remove this files/folders.

Maybe you might need to remove the contents of drs folder, too.
That is the folder that JDeveloper delpoys the application in order to run it in the embedded WLS.
It is located under %JDEV_SYSTEM_ROOT%/\o.j2ee
eg
C:\Documents and Settings\user\Application Data\JDeveloper\system11.1.1.4.37.59.23\o.j2ee\drs

  1. Good approach this is too frequent an error now days. just to add java.lang.ClassNotFoundException comes because ClassLoader fails to load the class requested at runtime.This is mostly an environmental issue which depends upon whether request class is present in Classpath or not.to solve this error best approach is to first find the jar file in which problematic class exists and then examine your classpath.also don't confuse this with NoClassDefFoundError which is entirely different , for details see here NoClassDefFoundError vs ClassNotFoundException in Java

  2. Exactly!
    In the case of JDeveloper, while deveoping the wizard "thinks" that the Model project, that your BC are, is a ViewController project and adds the appropriate files. While running the application, server tries to launch the application from the Model project but as you correctly stated, it fails as it does not have the appropriate classes/jars in the classpath.
