Dear Gurus,
I am writing a servlet in order to
access WHOIS domain registration
database. I've read all of the messages
in this forum with respect to this
technique, so please do not redirect me
to them.
When sending the request through a
socket( OutputStream out = socket.getOutputStream();
String str = "kalyan.com";
byte buf[] = str.getBytes();
out.write(buf);) everything works fine,
however when I try to get the data from the socket
back ( InputStream in = s.getInputStream();
while ((c = in.read()) != -1) {
strRawResponse += (char)c;
} ) the process takes an enourmous amount of
time and sometimes returns an error.
Please advise me on how to approach this problem.
Here is the full code:
import java.net.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public
class whoisSuccess2 extends HttpServlet {
public void init(ServletConfig config) throws ServletException {
super.init(config);
}
public void doGet (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
res.setContentType("text/html");
String dome = req.getParameter("dome");
ServletOutputStream output = res.getOutputStream();
int c;
Socket s = new Socket("rs.internic.net",43);
InputStream in = s.getInputStream();
OutputStream out = s.getOutputStream();
String str = "kalyan.com";
byte buf[] = str.getBytes();
out.write(buf);
String strRawResponse = "";
while ((c = in.read()) != -1) {
strRawResponse += (char)c;
}
output.println("<html>");
output.println("<head><title>Whois</title></head>");
output.println("<body>");
output.println(strRawResponse);
output.println("</body></html>");
}
}
