[wsia] [wsia-req-Financial Charting Service] divine details

["Quintas, Peter" <Peter.Quintas@divine.com>]

The details surrounding the divine-FAME communication in the Financial Charting Service scenario are as follows:

 

The divine Financial Charting component has forms on the left and top of the component that wrap an include of a iChartz (FAME) URL.  The surrounding forms construct the iChartz URL with the corresponding input parameters.  Below is a sample URL:

 

http://www.ichartz.com/ichartz/servlet/iChartzImage?profile=<PROFILE_ID>&id=TKR:US;DVIN&timeframe=1year&frequency=daily&ct=line&height=300&width=540&refresh=true

 

Note that the <PROFILE_ID> part of the URL would specify who the requesting client is of the stock chart… This is the interesting part (or actually the uninteresting part)…

 

The look-and-feel of the component is controlled in 2 ways.  The forms and surrounding markup are produced by the divine component, thus following the style and skin of the divine application.  The way that the look-and-feel of the chart is rendered is this…

 

iChartz has a tool in which administrators of the consuming application (divine’s application) can log in to and specify the look-and-feel of the resulting chart… manually.  So the chart is rendered using the fixed style on a client-by-client basis.  (By client, I mean if we install our application at a client, they can only have one look-and-feel for all of their charts).  

 

This scenario is screaming for more view-level dynamic adaptations.  Also note the limitation for adapting the view as divine re-produces this application.

 

I hope this helps to shed some light on some of the details here…
