doPost method

[Amitabh Sinha55555]

Dear Forum member my problem relates to the doPost method it goes as follows:
i have to call doPost method of servlet from a swing
form.Now for that u have to open a URL and
urlconnection and make a printwirter object.
i tried this but its not working.

URL url = new URL(stra);
file://while(true)
// {
URLConnection urlcon1 = url.openConnection();
urlcon1.setDoOutput(true);
PrintWriter out = new PrintWriter
(urlcon1.getOutputStream());
Set set = form1.hm.entrySet();
  Iterator  i1  =set.iterator();
InputStream input = null;
String ashu1 = "";
while(i1.hasNext())
  {
  Map.Entry me = (Map.Entry)i1.next();
  name = me.getKey().toString();
  value = me.getValue().toString();
  // out.print(name + "=" + value);
  char ch ='\n';   
  if(i1.hasNext()) ch='&'; else ch ='\n';
  
  System.out.print(name + "=" + value);
ashu1+= (name + "=" + value+
ch);//URLEncoder.encode(value)
// out.print(name + "=" + value + ch);
System.out.print(name + "=" + value+
ch);//URLEncoder.encode(value)
//
System.out.print("(((((((((((((((((()))))))))))))))"+ashu1);
}
//
System.out.print("(((((((((((((((((()))))))))))))))"+ashu1);
String search = "&=";
int i11 = ashu1.indexOf(search);
int length = ashu1.length();
String ashu11 =
ashu1.substring(0,ashu1.lastIndexOf(search));
StringTokenizer st = new
StringTokenizer(ashu11,"&");
String token = null;
do 
{char ch;
if(st.hasMoreTokens()) ch='&'; else ch ='\n';
token = st.nextToken();
out.print(token + ch );
System.out.print("***********"+token);
} while (st.hasMoreTokens());

It doesn't appear by your logic that the post String is getting formatted properly. I think I've captured all your problems and rules. This is how I would solve this. Note, because I fully form the Post String I can see what I'm sending and possibly what is preventing the proper post of information.

        URL             url = new URL(stra);
        URLConnection   urlcon1 = url.openConnection();
        urlcon1.setDoOutput(true);
        PrintWriter out = new PrintWriter(urlcon1.getOutputStream());
        Set         set = form1.hm.entrySet();
        Iterator    i1 = set.iterator();
        InputStream input = null;
        String      ashu1 = "";
        int         count = 0;
        while (i1.hasNext())
        {
            Map.Entry   me = (Map.Entry) i1.next();
            String      name = me.getKey().toString().trim();
            String      value = me.getValue().toString().trim();
            if (name.length() > 0 && value.length() > 0)
            {
                if (count > 0)
                {
                    ashu1 += "&";
                }
                ashu1 += (URLEncoder.encode(name) + "=" 
                          + URLEncoder.encode(value));
                count++;
            }
        }
        System.out.println(ashu1);
        out.println(ashul);
