Hi mark, It is a good question! I've not used them so far but i think the new java Properties class is designed to supply config. info to a system. If you have a command processor class that gets the connection maybe you should make it's name a property so you can have a different class in the web env. from other env? hth - I'n not n expert on this stuff - just in case no=one else replies! K.
