No thats all sorted, its the error message with the driver thats the prob.
thanx anyway,
j.f.
hi all,
I have tried using this code to access a mysql database but alas i get an error 'Exception in thread "main" java.sql.SQLException: No sutible driver'
but I installed the driver from 'http://mmmysql.sourceforge.net/' and set the CLASSPATH up correctly!?
Here is the code
--------------------------------------------------------
import java.sql.*;
public class Connect{
public static void main(String args[]) throws Exception{
Connection con = null;
try{
String url = "jdbc://hostname:3306/database";
Class.forName("org.gjt.mm.mysql.Driver");
con = DriverManager.getConnection(url, "uname", "pwd");
if(con != null){
System.out.println("whehe");
}
}
finally{
if(con != null){
try{
con.close();
}catch(Exception e){
System.out.println(e.getMessage());
}
}
}
}
}
Hello all,
I have tried to send mail using this code...
----------------------------------------------
import java.io.*;
import java.net.*;
/**
* This program sends e-mail using a mailto: URL
**/
public class SendMail {
public static void main(String[] args) {
try {
// If the user specified a mailhost, tell the system about it.
if (args.length >= 1)
System.getProperties().put("mail.host", args[0]);
// A Reader stream to read from the console
BufferedReader in =
new BufferedReader(new InputStreamReader(System.in));
// Ask the user for the from, to, and subject lines
System.out.print("From: ");
String from = in.readLine();
System.out.print("To: ");
String to = in.readLine();
System.out.print("Subject: ");
String subject = in.readLine();
// Establish a network connection for sending mail
URL u = new URL("mailto:" + to); // Create a mailto: URL
URLConnection c = u.openConnection(); // Create its URLConnection
c.setDoInput(false); // Specify no input from it
c.setDoOutput(true); // Specify we'll do output
System.out.println("Connecting..."); // Tell the user
System.out.flush(); // Tell them right now
c.connect(); // Connect to mail host
PrintWriter out = // Get output stream to host
new PrintWriter(new OutputStreamWriter(c.getOutputStream()));
// Write out mail headers. Don't let users fake the From address
out.print("From: \"" + from + "\" <" +
System.getProperty("user.name") + "@" +
InetAddress.getLocalHost().getHostName() + ">\n");
out.print("To: " + to + "\n");
out.print("Subject: " + subject + "\n");
out.print("\n"); // blank line to end the list of headers
// Now ask the user to enter the body of the message
System.out.println("Enter the message. " +
"End with a '.' on a line by itself.");
// Read message line by line and send it out.
String line;
for(; {
line = in.readLine();
if ((line == null) || line.equals(".")) break;
out.print(line + "\n");
}
// Close (and flush) the stream to terminate the message
out.close();
// Tell the user it was successfully sent.
System.out.println("Message sent.");
}
catch (Exception e) { // Handle any exceptions, print error message.
System.err.println(e);
System.err.println("Usage: java SendMail [<mailhost>]");
}
}
}

The program hangs on 'c.connect()' trying to find a connection i guess.
I submitted my mail host and my own e-mail address but it just hangs and somtimes it states that the connection is not found what am i doing wrong.

confused person.
