[Zope] Finding and killing the POSKeyError in ZODB

[Jake]

I have been reading the instructions in ZopeLabs trying to figure out  
how to get rid of a few POSKeyErrors, but I can't get by this one point.

"Now that we have an OID, let's resolve that to the actual object  
like so:

 >>> app._p_jar[oid]

Once you have the object, you can start getting clues about it. It's not
acquisition-wrapped so you can't easily find out its containment path,
but you can find out its ID, mod time, type, and owner, like so:"

I get:

 >>> obj = app._p_jar['\x00\x00\x00\x00\x00\x04\x9d#']
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
AttributeError: 'function' object has no attribute '_p_jar'


Any help?
