Offline scenario - post data from saved form to SQLServer

Question

This is the scenario am struggling to develop. User downloads the interactive form.  Goes offline. I mean no connection to the Web Application Server. But he will have access to a SQLServer database (it may be on his machine or in his intranet). He will fill the form and save it on his local hard disk. Now, I want his saved form data to be posted to the SQLServer.  I thought about a couple of ways to do this.
1) Is it possible to change the control type of 'Submit' button to submit and then in the URL field, call some ASP page (this page is deployed on a local IIS) and then submit the form fields to that ASP page which takes care of database connection, posting etc. So user downloads form only once. But fills it with different data each time and clicks submit. First of all, will submit button work when the form is not opened in web browser? I mean when it is saved on a local hard disk opened in a standalone Adobe Reader?
2) Is it possible to write some java program using any APIs and extract the data from the form saved on local hard disk? It may be possible because I have the .xdp file for the form. But I dont know if there are some APIs available to do the same.
Any inputs whether these ideas are feasible? Any other new ideas are also welcome. Thanks in advance.

Hi Narayana,
if you want to export xml data from Reader to local disk you can use a command:
xfa.host.exportData("",0);
It works like from menu Export data from Forms.
To your second post:
Yes, you can save form in Adobe Live cycle designer as pdf and you can open it in Adobe Reader and test it. It will work.
In tab Submit for your button set these properties:
Submit Format: XML Data (XML)
Submit to URL: url of your page
Encoding: UTF8
Here is a sample code in c# for asp.net. Insert method save to your asp.net page and call it from method Page_Load.
          using System;
          using System.IO;
          using System.Web;
          private void save()
               const int coniBufferLen=1024;
               string lsTmpFile;
               try
                    lsTmpFile="c:\adobe\body.pdf.xml.txt";  // File on local disk where to save xml data sent by Reader. IIS needs rights to write here.
                    FileStream loFS=null;
                    try {loFS=File.Create(lsTmpFile);}
                    catch (Exception e1)
                         // TODO
                         return;
                    int liCelkem=Request.ContentLength;
                    int liNacteno=0;
                    byte[] laResponse=null;
                    int liLen=Math.Min(coniBufferLen,liCelkem-liNacteno);
                    while (liLen>0)
                         try
                              laResponse=Request.BinaryRead(liLen);
                              loFS.Write(laResponse,0,liLen);
                         catch (Exception e1)
                              try {loFS.Close();}
                              catch {}
                              try {File.Delete(lsTmpFile);}
                              catch {}
                              // TODO
                              return;
                         liNacteno+=liLen;
                         liLen=Math.Min(coniBufferLen,liCelkem-liNacteno);
                    loFS.Close();
               catch (Exception e2)
                    // TODO
                    return;
