thanx for the info simon
so, how can i place a value into the jad file on the fly, can you
send me any example link or code.

You'd put a value in your jad file something like this:

user-phone-number: @phonenumber@

Then you'd have an HTML page with a form with an input

        <input name="phonenumber" type="text">

The action of the form go to either a CGI or a Servlet. Actually a PERL CGI
might be a good solution here, because this sort of thing is one of the
(few) things PERL is good at, but because I'm used to Java I'd use Java.

The servlet would do something like (note: off the top of my head, not

import org.apache.regexp.*;


protected void doGet( HttpServletRequest req, HttpServletResponse resp)
               throws ServletException,
        doPost( req, resp);

protected void doPost(HttpServletRequest req, HttpServletResponse resp)
               throws ServletException,
        String pattern = "@([a-zA-Z0-9_-]+)@";
        String phonenumber = req.getParameter( "phonenumber");
        ServletOutputStream out = resp.getOutputStream()

        RE regexp = new RE( pattern );

        BufferedInputStream buffy =
                new BufferedReader(
                        new InputStreamReader( new FileInputStream( jadFile)));

        for ( String line = buffy.readLine(); line != null; line ++)
                if ( phonenumber != null)
                        regexp.subst( line, phonenumber);

                out.println( line);

but the actuall jad file doesnt downloaded into the client phone ?

Yes, it does. That's how 'Over the Air' provisioning works.
