Do something like this in your controller

def configure_charsets
      super
      @response.headers["Content-Type"] = "text/vnd.wap.wml;
charset=utf-8"
end

I have used the xml builder templates to make wap output. Start with two  
lines like this.

xml.<<"<?xml version=\"1.0\"
encoding=\"utf-8\"?>"
xml.declare! :DOCTYPE, :wml, :PUBLIC, "-//WAPFORUM//DTD WML 1.3//EN",
"http://www.wapforum.org/DTD/wml13.dtd"

Hi Biji,

I couldn''t try this, but this should help you anyways:
You have to serve the document with the correct content type header for 
wml, which should be "text/vnd.wap.wml", so in your controller you 
should have a

@headers["Content-Type"] = "text/vnd.wap.wml"

HTH,
Michael

Hi!

I think the best thing is to use an after_filter like this:

class ApplicationController < ActionController::Base
    after_filter :set_content_type

    def set_content_type
        @headers["Content-Type"] ||= "text/vnd.wap.wml"
    end
end

Either you enable the filter in your ApplicationController (to enable 
the wap header for the complete application) or only in specific 
controllers. You can put the method set_content_type in your 
ApplicationController and just enable the filter in each controller with 
after_filter :set_content_type.

Using an after_filter and ||= allows you to set the header in some 
actions manually. Only if that header is not set the filter sets the wap 
header.

Bye,
