Answer 1

its really easy
To read from server, use something like:
HttpConnection connector = null;
InputStream inp_stream = null;
OutputStream out_stream = null;
void CloseConnection()
     if(inp_stream!=null)inp_stream.close();
     inp_stream=null;
     if(out_stream!=null)out_stream.close();
     out_stream=null;
     connector.close();
     connector = null;
public void getResponse(String URL,String params)
  try
     if(connector==null)connector = (HttpConnection)Connector.open(URL);//URL of your text file / php script
     connector.setRequestMethod(HttpConnection.POST);
     connector.setRequestProperty("User-Agent","Profile/MIDP-2.0 Configuration/CLDC-1.1");
     connector.setRequestProperty("content-type", "application/x-www-form-urlencoded");
     //connector.setRequestProperty("charset","windows-1251");
     //*** If you need to send ("arg1=value&arg2=value") arguments to script use this:
     out_stream = connector.openOutputStream();
     byte postmsg[] = params.getBytes();
     out_stream.write(postmsg);
     int rc = connector.getResponseCode();//in any case here connection will be opened & closed
     if (rc != HttpConnection.HTTP_OK)
          CloseConnection();
          throw new IOException("HTTP response code: " + rc);
     inp_stream = connector.openInputStream();
     int pack_len = inp_stream.available();
     byte answ[]=new byte[pack_len];
     inp_stream.read(answ);
     CloseConnection();
     ProcAnswer(answ);//process received data
  catch(Exception ex)
     System.err.println("ERROR IN getResponse(): "+ex);
} And you can read from resource file like
public void loadFile(String filename)
    DataInputStream dis = new DataInputStream(getClass().getResourceAsStream("/"+filename));
    String str="";
    try
         while (true)
            ch = dis.read();//read character
            if(ch=='\r')continue;//if file made in windows
            if(ch=='\n' || ch==-1)//end of line or end of file
                if(str.length()==0)continue;//if empty line
                //do some thing with "str"
                if(ch==-1)break;//it was last line
                str="";//next line
                continue;
             str+=(char)ch;
       dis.close();
   catch (Exception e)
       System.err.println("ERROR in loadFile() " + e);
}Welcome! =)
