nah....it's something you need to do often and it can be easily done using the avalon lifecycle. we've got Parameterizable and Parameters for passing in property-like stuff, but the use of that in current container is not quite as easy as using Configuration and Configurable. What you do is provide a xml configuration file, and then that configuration is handed in as an object hierarchy (think DOM, but way easier to use) to the component by the container (it calls the configure() method on your component). This is guaranteed to happen before initialize() is called. (While it is of course possible to put stuff like this in a Context, using a Configuration is usually easier and more straightforward for data that is naturally represented in XML) How to do this exactly differs a little per container. If you are using phoenix, your best bet is to take a look at how the demo apps do it (somewhat out-of-date downloads from http://cvs.apache.org/~hammant/apps/, for the most recent stuff you'll have to get this from the jakarta-avalon-apps CVS) for clues. I'm CCing the avalon-user list as that's really the best place for talk about this. no worries though ;) regards, - Leo Simons -- To unsubscribe, e-mail: <mailto:avalon-dev-unsubscribe@;jakarta.apache.org> For additional commands, e-mail: <mailto:avalon-dev-help@;jakarta.apache.org>
