Hi al .....

I try to connect database by servlet and storing the
result to applet.
Servlet is working good, servlet-applet communication
also ok.

The problem is the result not appear ( by appletviewer
or from netscape).
Help me please.

This is the servlet code :..........res.setContentType("text/plain");PrintWriter out = res.getWriter(); 
   try {         Class.forName("org.postgresql.Driver");          con = DriverManager.getConnection(
"jdbc:postgresql:lecture","me", "pass");         stmt = con.createStatement();     rs = stmt.executeQuery("SELECT K_ID,
K_NAME,
TERM, DATE FROM KAMOKU");       while(rs.next()) {       out.println(rs.getString(1) + " " +
rs.getString(2) + " " +           rs.getString(3) + " " +
rs.getDate(4).toString());       }    }   catch(ClassNotFoundException e) ..........


The applet code :

import java.applet.*;
import java.awt.*;
import java.io.*;
import java.net.URL;
import com.oreilly.servlet.HttpMessage;

public class applettoservlet2 extends Applet
{   TextArea httpText;      public void init()   {       httpText = new TextArea();         }
   public void start()   {       refresh();   }
   private void refresh()   {       httpText.setText(HttpText());   }
   private String HttpText()   {       try       {         URL url = new
URL("http://localhost:8088/servlet/servlettoapplet");         HttpMessage msg = new HttpMessage(url);
InputStreamin = msg.sendGetMessage();         DataInputStream result = new
 
DataInputStream(new
BufferedInputStream(in));         String date = result.readLine();         in.close();         return date;       }
       catch(Exception e)       {           e.printStackTrace();           return null;       }   }  
}


Thank you,
S.A.Pamungkas
