WAP/WML support to existing application

[Mike Landis <mi...@hotmail.com>]

Hello,
How or is is possible to add WAP/WML support to existing Struts application?
I would like keep Web based (html) application as untouchable as possible.
Are there any possibilities to configure Struts so, that WAP and Browser 
requests
will be handled in their own actions? If yes, how or is it wrong approach?
In my case there is no need/want to XML/XSLT generation so I can 'replicate' 
JSP pages depending on their content type (wml and html).
Can anyone give me some tips how to add WAP support to existing Web 
application?

Thanks,
mike

The simplist way would be just to have WML copies of your JSP's

Something like this at the top of you jsp.. (i'll have to check but i 
think its correct. JSP's default to contentType="text/html")

<%@ page language="java" contentType="text/wml" %>

If you want to minimize repetitive markup between html and wml versions 
then some cunning use of tiles and a WML layout could do the job... But 
this would really be up to you. Having stuff too rationalized can make 
applications harder to maintain.. I'd add new views but use the same 
actions.

The other option would be the parse the HTML version into a WML 
versions, personally I think that this is a little more elegant but 
would confuse maintainers more. . Youu could go for best of both worlds 
and do an XSL transformation at build time to generate the additional 
jsp's, but unless your site is huge this could take more time than this 
would warrant.

1 issue affecting WML from JSP.
The only problem with WML versions and JSP is that a few of the 
original nokia wap phones (7110) have trouble with white space at the 
top of WML pages. I worked for an agency where the contact for one of 
their clients had one of these phones and it was a pain in the arse. I 
ended up doing all my WML as servlets because of the control over white 
space. You can replicate this bug with the original version of the 
nokia wap kit, the emulator has the same issue.
