Re: [Springframework-developer] Example classes needed and naming convention

Forgot that SF sent me a notification ... sorry about that.
There *really* were problems but not with that mail.
In addition to the naming conventions for the jar packages:
Should it be
1a) jürgen.jar or 1b) jürgen-full.jar
or
2a) juergen.jar or 2b) juergen-full.jar
Maybe Spring could provide some kind of converter for developers
with names containing German 'Umlaut' :-)
Regards,
Lars
