Adding mimme types -- was: [Zope] can't use new mime type (content_type)

I am having a similar problem with .jnlp files.  In the past 
I have put them in the ZOOB and set the type by hand.  Now, for 
management reasons I want to maintain them in the local file system.

To make this work and get the mime type set right, I modified the 
LocalFS product adding entries in the _types dictionary and icon 
dictionary suitable for .jnlp files.  For some unknown reason, this
does not seem to work.  The typemap displayed in the ZMI (generated 
from the _types dictionary) does not reflect the changes I made in 
the _types dictionary.  Nor does the icon list.  Are there other places 
in the system that need to be updated to add a mime type?

BTW--it seems to me that mime types are mutable enough collect them in a
single place rather than having them defined in multiple places as seems
to be the case.
