David promptly replied: Hi Jerry, It's hard to diagnose from what you've sent me. Can you send me the full traceback (from the HTML source code of the error page)? That will make determining where the error occurred a lot easier. So the very least I could do was respond with: ------------------------------------- The first one: Traceback (innermost last): File /l01/Zope-2.2.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /l01/Zope-2.2.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 187, in publish File /l01/Zope-2.2.1-linux2-x86/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: POPMailAccountBase) File /l01/Zope-2.2.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 171, in publish File /l01/Zope-2.2.1-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: index_html) File /l01/Zope-2.2.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: index_html) File /l01/Zope-2.2.1-linux2-x86/lib/python/OFS/DTMLMethod.py, line 172, in __call__ (Object: index_html) File /l01/Zope-2.2.1-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: index_html) File /l01/Zope-2.2.1-linux2-x86/lib/python/DocumentTemplate/DT_Util.py, line 337, in eval (Object: ListMessages()) (Info: ListMessages) File <string>, line 0, in ?

Hi David,

I'm looking at your Pop3 Client tool for Zope and have hit a snag. Is there any documentation about correct usage, or example (Zope) code?

I'm using Zope 2.2.1 on Redhat Linux, with PopMailBase .0.0.3, and PopMail .0.0.2

I have looked over POP.py, and have a glimmer of what to do to call these methods and functions. I have added a Pop Client Folder, and a client account object, but when I try to use the "View" tab in the Zope TTW GUI, I get the tracebacks, below.

The 'error_proto' is a reference to the first class listed in poplib.py, which simply 'pass(es)' when an Exception is used as a parameter. One thing I noticed is that poplib seems to treat error_proto as a function sometimes, which strikes me as odd. Some Pythonic stuff boggles my mind. Now you know as much (hopefully much more!) than I do.

Thanks for any help! Jerry S.
