More Improvements from Nicholas Albion
I got another version of WALL from Nicholas Albion which improves on the one sent by Brandon last month, It can be download from here.
Here is the message I got from Nick. On behalf of the WURFL community, thanks nick.

Hi Luca,

Here's my Christmas present to the WURFL/WALL community.  
I've taken Murray Brandon's code for a test drive and have 
to say that I like it.  I like the idea of only having to 
check if the device supports WML/CHTML/XHTML once, and 
storing that in the DocumentInfo object.  I've changed 
that code so that it only needs to do an int comparison 
instead of a string comparison.

I've also set up Murray's code in a seperate directory, 
so that I could compare it with your original code - and 
go back to that if I came across any problems with his code.  
So far it's been good though, I've even added a few other 
tags/classes of my own.

I'm trying to design my site (web application) so that 
it will support AJAX on PCs, so I've added "id" and 
"style_class" attributes to the 
 and 
 wall tags, 
and also created a  tag.  Where the page can be 
broken up into tiles (as per struts:tiles), I've created 
a  tag which breaks large pages up into cards for 
WML, but renders as 
s for XHTML and CHTML.

I trust Murray will be impressed that I've made use of 
his XxxRenderer classes from a servlet.  I've modified 
his code so that it uses java.io.Writer, rather than 
JspWriter - this allows the servlet to render Wall 
tags using the response's PrintWriter.

I've added more notes in txt file within the zip file.  

I hope you're able to put this code to good use.

Regards,

Nick
