dynamic page (server-client)

hi guys, wonder if some of you have already gone through something like this.

I'm trying to develop a client-server application for wap, I have a php page that sends it's data to a remote socket server(upon submit), the server is getting the message alright but the problem occurs when I try to give as a reply a supposed to be a dynamic page

here is the code smippet in the server to which the page sends data into:

StringBuffer sb = new StringBuffer();



sb.append("<?php header(\"Content-Type: text/vnd.wap.wml\"); ?>");
sb.append("echo '<?xml version=\"1.0\"?>';");
sb.append("ob_start();");
sb.append("?>");

sb.append("<!DOCTYPE wml PUBLIC '-//WAPFORUM//DTD WML 1.3//EN' 'http://www.wapforum.org/DTD/wml13.dtd'>");



sb.append("<wml>");
sb.append("<card id='main' title='my game'>");
sb.append("<p align='center'>");
sb.append("<br/>");
sb.append("<big>");
sb.append("sample reply");
sb.append("</big>");
sb.append("</p>");
sb.append("</card>");
sb.append("</wml>");

this.socketChannel.write( charsetEncoder.encode(CharBuffer.wrap(sb.toString() + "\n" ) ) );


-----------------
expecting to display this dynamic page but I keep getting an error that says:

"The WAP site you have requested () could not be retrieved, due to some network error." - but the message has actually been sent, recieved by the server and been replied to..


Guys, do you have any idea about this? Or any suggestion, I would really appreciate it.
