[Zope] loading zclass from zeo client

[Erik A. Dahl]

I'm writing an external zeo client program that needs to interact with
zclasses.  When I try and load a zclass from the database I get the
following:

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/home/edahl/zope/lib/python/ZODB/Connection.py", line 471, in
setstate
    state = unpickler.load()
  File "/home/edahl/zope/lib/python/ZODB/Connection.py", line 142, in
_persistent_load
    return self[oid]
  File "/home/edahl/zope/lib/python/ZODB/Connection.py", line 103, in
__getitem__
    klass=self._db._classFactory(self, module, name)
  File "/home/edahl/zope/lib/python/ZODB/DB.py", line 119, in
_classFactory
    return getattr(__import__(location, _globals, _globals, _silly),
ImportError: No module named *UoHgL+xNgSWAgKCB4JIj9A==

When I look at the Basic tab on the zclass I see that its Class Id is
UoHgL+xNgSWAgKCB4JIj9A== but how do I import a class that is living in
the database?  Zope is doing it so I assume there is a function
somewhere for this but I have yet to find it.  Any help or examples
would be welcomed.

Thanks,
