Maybe
you should elaborate on you question! It is not really clear what you want to do!
I don't know anything about Director so I do not know what those files do but if you want to read them (and extract some data from them) in your servlet or jsp you can do that using plain File IO.
If you would like to refer to them in your resulting page (HTML,WAP, xml, ...) you can place the referring code in your jsp or servlet just like you would refer them in an HTML page. The only thing you will have to take care of is that those files are accessible to the browser. So you will have to put them in your webcontainer (just like you would a HTML page, image, CSS file, ...)
