We have web application that is almost 100% web service driven. We create & host oem versions of this web app for various vendors. Presently we are using asp.net & lots of user controls for the UI.
I am looking for solutions to providing the oem builds. Presently we turn features on & off server side, all configured in a database. I would like to provide more flexibility than is presently afforded. We are planning on letting oem's include custom css, and probably a ThemeRoller theme. I'm looking at the server portion though.
What do other frameworks & languages provide that could do something similar to this using a prebuilt control library to provide small & sometimes big customizations for different oems:
<%@ Page MasterPageFile="bla.master" CodeBehind="foo" %>
<our_widgets:widget1 default="true" other_setting="big" />
<our_widgets:widget42 somethin="5000" />
I am interested in how java, ruby, php other languages & frameworks do this.
