Hi Srini,

Is there any way to integrate WMl with servlets. I want to create a
dynamic WML thro servlets is it possible any URL guidance in this regard
will be highly appreciated.

Yes.
For all the specs, go to the WAP Forum (www.wapforum.org). For s/w try
Nokia, Ericsson, Phone.com, IBM Alphaworks - there are others, of course,
but they should keep you busy enough!
If you just want to create dynamic WAP content, then you'll be creating
WML files. For client-side scripting, there's also WMLScript (stored
in separate files, unlike the typical HTML/Javascript setup), and
also images - WBMP files (level 0 only at present = static monochrome).
Both WML and WMLScript content may be compiled.
MIME types for these are:
WML : text/vnd.wap.wml
Compiled WML : application/vnd.wap.wmlc
WMLScript : text/vnd.wap.wmlscript
Compiled WMLScript : application/vnd.wap.wmlscriptc
WBMP : image/vnd.wap.wbmp
When other WBMP formats appear, you'll need to change the last to
image/vnd.wap.wbmp; level=0
You can serve these from a standard Web Server - the handsets will
contact a gateway, which will then forward the request over http
to your server. So, your system will see a standard http request,
and you can serve it with static content or something generated
by servlets/JSP.
If you are intending to operate your own gateway, then you might be
interested in Nokia's WAP Server (and toolkit), as they have integrated
servlet support into their gateway product.

To handle WAP (the mobile equivalent of HTTP) is more problematic. I
suspect you'll need a servlet engine specifically designed to support
WAP.

Sorry Nic, but WAP is not a protocol as such - rather it's a coupled
collection of protocols and standards. There are HTTP-like protocols
within this framework - there's WSP the Wireless Session Protocol and
WTP - the Wireless Transport Protocol, but a WAP developer doesn't
need to worry about them for anything other than better insight into
what WAP's about.
All the best,
Anthony Scott-Hodgetts
