Store and Read key/value pairs

I have a need to store some user selectable options for a struts app, but am waffling as to the best way to store those. Are there any portable / acceptable ways to store key value pairs somewhere in the application, a key interest here being that the mechanism I use has to be writable. I can add and use a table for this in a database, but it seems a bit overkill.
Thanks, Paul

Not really a Struts question. Moving to Java in General (Intermediate).

For key/value pairs that are Strings, look at the Properties class in the java.util package. It is designed for exactly this purpose.

Thanks, that looks interesting, and I'll look into it further. My primary concern with something this generic though, and perhaps there isn't a good answer, is being allowed to write to the file system when run under a servlet container (ie. Tomcat 4.x).
Thanks again, Paul
