InstantiationException -- need guidance

Hello All:

In one of my database classes for a test application that
I am writing, I am getting the exception below on my server
process.

The problem is occurring when I try to create a new database
object from within a method on a current database
object.  In my example, I have a pre-existing PersonInfo
object which is trying to create a PersonName object.

In my PersonInfo object, I have this method:
  public void addToNames(String name) throws Exception {
    if( names == null )
      names = new OrderedSet();
    PersonName personName = (PersonName)
database().createObject(PersonName.class.getName());
    personName.setName(name);
    names.add(personName);
  }

The failure is occurring on the database().createObject() call.

I did a fresh checkout from the CVS sources and build just now,
so this is the current code.

I am still trying to trace it down, but I went thru the
class.newInstance() call in my debugger and it was fine and
went back into the Server code for the next Event from the
Client.  But, since there is a lot of code here and I am not
very familiar with it, I am hoping that someone can guide
me on what to look for. 

I am attaching my sources in case it helps.

Thanks,
	Neil.
