Cayenne and classpath question and help

Hi,

I have an application that dynamically loads jar files and reloads them 
when they are changed.  Unfortunately I'm have an issue getting Cayenne 
to see the classes inside one of these dynamically loaded jar files. I 
have some test code that looks roughly like this.

import com.dbclientbase.Database.Account;
public class blah

   public testMethod(){

             Account ac = new Account();  // This object instantiates 
without an error so it's visible to app outside of Cayenne

             ObjectContext oc = DBClientBase.getObjectContext(); // This 
method generates the ServerRuntime and fails to get an ObjectContext to 
work with (error below)

  }
}

The error output below seems to suggest that Cayenne cannot access the 
Account class although I can successfully instantiate a non-Cayenne 
object.  What can I do to ensure that Cayenne also has access to the 
contents of a dynamically loaded and reloaded jar file?  I have found 
references to AdhocObjectFactory.getClassLoader()  but I can't find any 
examples on how to use it and I'm quite at a loss on how to even begin 
use it.

Thanks,

Andrew
