File Association problem on FC5/gnome

[James Pifer]

I'm running FC5 and I have java 1.5.0_09 installed. That's all fine
except that on my gnome desktop I have an OpenOffice spreadsheet with
the .ods extension. For some reason gnome sees the file as a Java
Archive first rather than a OpenOffice Calc file. I can do Open With and
see Open with "Spreadsheet", but how do I get it to default to that?
Right now the icon on the file is the Java icon. It's not a big deal,
just an annoyance. 

Been googling and haven't found an answer. Any help is appreciated.

Thanks,
James
