how can i embedd the user phone number into the .jar

Purely out of curiosity.

Why would I want my phone number 'embedded'
in your ..anything? What benefits does that bring
to me, as an end user?

this specific user in order to use my
application.

Pack the jar on the fly at delivery time? Actually, it would be much easier
to do it by substituting a value into the jad file at delivery time, which
is what I'm planning to do with bike-race monitoring software I'm
developing. The racer enters his race number and event code into a web
form, they get substituted into a jad file which gets delivered to him,
the jad file causes the phone to download and install the jar file, and
when the racer starts the tracker app it sends his race number back to the
server. His live position during the race then appears on Google Earth...
assuming good phone network coverage, of course!

thanx for the info simon

send me any example link or code.
?

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

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
tested):


import org.apache.regexp.*;

....

protected void doGet( HttpServletRequest req, HttpServletResponse resp)
throws ServletException, java.io.IOException
{
doPost( req, resp);
}

protected void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, java.io.IOException
{
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.
