question about DWR integration

[Ilya Liubovich <li...@hotmail.com>]

Hi,
I've asked this on the DWR mailing list, but never got a response.
May you be you can help.
The issue is the following:

I have an extension to requestProcessor which deals with authorizing 
requests based on request parameteres. I'd like to do the same to the 
requests directed to the DWR servlet.
My thinking was first, map url /dwr* to the ActionServlet, do the required 
checks in the
processMapping() of the extension of RequestProcessor, and then forward the 
request to the
DWR servlet.

Is this a right approach?
If so, could somebody advice how to do it?
Thanks, Lig

Hi Lig,

I think you would want to do two things... first, abstract out your 
authorization code from the RP into a filter... you should be able to 
slap this in front of vanilla Struts and get the same effect (perhaps 
with a little tweaking, since I'm not familiar with your implementation).

Next, map this filter to ActionServlet, as well as DWRServlet... DWR and 
Struts are really two different things (existing integration aside), and 
I don't think it would make much sense to run requests through Struts 
and then DWR... I can see why you'd think that with the auth code in the 
RP, but once its externalized, I think everything becomes quite a bit 
cleaner.
