Hi,

I tried the foll program but it is giving runtime errors. I am using postcast server as my smtp host.

import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;

public class sendMail{
public static void main(String[] a) throws Exception
{try{
String host="127.0.0.1";
String from="me@myweb.com";
String to="me@myweb.com";
Properties prop=System.getProperties();
prop.put("mail.smtp.host",host);
Session ses1=Session.getDefaultInstance(prop,null);
MimeMessage msg=new MimeMessage(ses1);
msg.setFrom(new InternetAddress(from));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
msg.setSubject("Urgent Message");
msg.setText("You won lottery!");
Transport.send(msg);}
catch(Exception e){System.out.println(e.getMessage());}
}
}


I am getting the following runtime error and I recieve no mail in my smtp server
java.lang.NoSuchMethodError: com.sun.activation.registries.MailcapFile.getMailcapList(Ljava/lang/String;)Ljava/util/Hashtable;
