Tapestry, request processing from another application - httpclient

Question

i'have two web appli, tapestry appli and a simple web appli(servelt). in tapestry appli , i have a form, and when it'll be sent, i call a httpClient for sending some informations to author appli using apache's httpClient. like this
void onSubmitFromForm() {
try {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://localhost:8080/appli2/recep");
post.setHeader("referer", "http://localhost:9090/app1/start");
List<NameValuePair> param = new ArrayList<NameValuePair>();
param.add(new BasicNameValuePair("_data", getData());
post.setEntity(new UrlEncodedFormEntity(param));
HttpResponse response = client.execute(post);
response ?????
} catch (Exception e) {
e.printStackTrace();
}
}
And in my servelt recep of the simple web appli(2) i do the same like below
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
try {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(request.getHeader("referer"));
post.setHeader("p",getP());
client.execute(post);
} catch (Exception e) {
e.printStackTrace();
}
}
So, my recep reviev data from my form but it'cannot response it, i'would that tapersty appli could recieve the param 'P' from the simple web appli ?
thanks

If I'm correct you want your tapestry application to POST some form data received from a form submit within Tapestry to a servlet running on another application.
If this is what you want then what is missing is the haneling of the request and constructing a response in your servlet. Because both your tapestry page and your servlet are POST'ing meaning neither constructs a response for your HttpClient to deal with.
In your servlet you could:
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
response.setContentType("text/plain");
PrintWriter out = response.getWriter();
out.println(getP());
out.close();
}
And deal with the response in your tapesty form handler.
