javaMail question ( the same as previous topic with source code)

[Yurong Chen]

Hello, I use javaMail for my javabean to send email in my web server. However I got the following error message when I compile it.:

java.lang.NoClassDefFoundError: com/sun/mail/util/BEncoderStream
at javax.mail.internet.InternetAddress.setPersonal(InternetAddress.java:168)
at javax.mail.internet.InternetAddress.(InternetAddress.java:119)
at javax.mail.internet.InternetAddress.(InternetAddress.java:105)
at Email.send(Email.java:78)
 

my javabean Email.java has the source code as followed:

public void send() {
 
validate();
 

if (!errors.isEmpty())
return;
 
try {
InternetAddress from = new InternetAddress(getFromAddress(), getFromName());
InternetAddress to = new InternetAddress(getToAddress(), getToName());
 
Properties props = new Properties();
props.put("mail.smtp.host", fieldSmtpHost);
 
// Create a mail session
Session session = Session.getDefaultInstance(props, null);
session.setDebug(true);
 
mail = new MimeMessage(session);
mail.setFrom(from);
mail.addRecipient(Message.RecipientType.TO, to);
mail.setSubject(getSubject());
mail.setContent(getBody(), "text/plain");
} catch (Exception exc) {

}
 

(new Thread(this)).start();
 
return;
}  

My application FinishRegister.jsp have the followed source code:

 <% java.lang.String userName = (String)session.getAttribute("forename")+(String)session.getAttribute("lastname"); 
   java.lang.String userEmail = (String)session.getAttribute("email");
   java.lang.String password = (String)session.getAttribute("password"); 
   java.lang.String challengeQuestion = (String)session.getAttribute("question");
   java.lang.String answer = (String)session.getAttribute("answer");
   java.lang.String body = "Welcome to Bioinformatics webserver!Thank you for registering with our bioinformatics webserver."
+ " This automated reply is for your reference only. User Name: " + userName+" Email: "+userEmail
+ "Password: "+password+"Challenge Words: "+challengeQuestion+" , the answer is  " + answer;
   java.lang.String fromName = "Yurong Chen";
   java.lang.String smtpHost = "mailhost.dcs.shef.ac.uk";
   java.lang.String fromAddress = "[e-mail]";
   java.lang.String subject = "Registration";%>
 
<%
    email.setFromName(fromName);
    email.setSmtpHost(smtpHost);
    email.setFromAddress(fromAddress);
    email.setBody(body);
    email.setSubject(subject);
    email.setToAddress(userEmail);
    email.setToName(userName);
    email.send();
 %> 

Thank you in advanced!

It looks like you need to add the path of com.sun.mail.util.BEncoderStream to your server's classpath.

It is the problem! Thank you ! I ignored that package when I imported the javax.*.
However, I met a new problem now. I sent out the message without any error now. But I didn't receive the email in the destination email address. I wrote a test program for that and got the following message:

javax.mail.SendFailedException: Sending failed;
  nested exception is:
class javax.mail.MessagingException: IOException while sending message;
  nested exception is:
javax.activation.UnsupportedDataTypeException: no object DCH for MIME type text/plain
at javax.mail.Transport.send0(Transport.java:218)
at javax.mail.Transport.send(Transport.java:80)
at SendEmail.main(SendEmail.java:43)  

Could you help me to explain that?
Thanks in advance!
Yurong

Yurong.. this is not an answer to your problem... i don't know... .. but after looking at your code, have you tried using JSTL to send email?, it is BEAUTIFUL... I think it is called mailer taglib. I've used and it's great!
cheers

Include com.sun.mail.handler package in ur class path.

[Yurong Chen]

Dear Andres and Ankur,

I think my problem is on setting the environment variables. However, I have set the package into my classpath. It still gave me the error message when I compiled the program:

 javax.activation.UnsupportedDataTypeException: no object DCH for MIME type text/plain
at javax.activation.ObjectDataContentHandler.writeTo(DataHandler.java:841)
at javax.activation.DataHandler.writeTo(DataHandler.java:295)

at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:324)
at javax.mail.Transport.send0(Transport.java:163)

javax.mail.SendFailedException: Sending failed;
  nested exception is:

  nested exception is:

at javax.mail.Transport.send0(Transport.java:218)
at javax.mail.Transport.send(Transport.java:80)
at SendEmail.main(SendEmail.java:43) 

Should I put the source code of my program here? It is a little long.

  import java.util.Properties;
 import javax.mail.*;
 import javax.mail.internet.*;
 
 
 public class SendEmail{
public static void main (String args[]) 
throws Exception {
 
   String password = "124124";
   String challengeQuestion = "How are you?";
   String answer = "I am fine";
   String toAddr = "[e-mail]"; 
   String toName = "Chen Yurong";   
   String body = "Welcome to Bioinformatics webserver!Thank you for registering with our bioinformatics webserver."
+ "This automated reply is for your reference only. User Name: " + toName+" Email: "+toAddr
+ "Password: "+password+"Challenge Words: "+challengeQuestion+" , the answer is  " + answer;
   String fromAddr = "[e-mail]";
   String fromName = "Yurong Chen";
   
   String subject= "Registration on the bioinformatics web server";
   
   //Specify the SMTP Host 
   Properties props = new Properties();
   props.put("mail.smtp.host", "broadstone.sheffield.ac.uk");
   
   //Create a mail session, turn on the debug flag
   Session ssn = Session.getDefaultInstance(props,null);
   ssn.setDebug(true);
   
   try{
   //set the from information
InternetAddress from = new InternetAddress(fromAddr, fromName);
//set the to information
InternetAddress toUser = new InternetAddress(toAddr, toName);

//Create the message
Message msg = new MimeMessage(ssn);
msg.setFrom(from);
msg.addRecipient(Message.RecipientType.TO, toUser);
msg.setSubject(subject);
msg.setContent(body, "text/plain");

//Send the message across
Transport.send(msg);
System.out.println("send successful!");
   }
        catch (MessagingException mex) {
        mex.printStackTrace();
   }
   }
   
 } 

Thank you for your kind help!

Dear Andres,
I want to try the JSTL to send email after my program running. It should be brilliant. I need time to learn that.

Dear All,
Thank you very much! I have solved the problem in Windows. However, I am still trying to set the right path in my web server.

Hi,

I encounter a similar problem when i send a e-mail form my SMTP code.I am suing mail.jar(version 1.3.2) and activation.jar(version 1.0.2)- doenloaded from sun's site.And i have included it in the class-path.

This is the stackTrace i get when i set session.setDebug(true).
Pls. do let me know how you resolved it.

Hi Yurong,

could you let us know how you solved the problem? I also got the same problem.


Thanks

Just having mail.jar and activation.jar in your classpath is sufficient for compiling, but not for runtime. Depending on which protocols you use, you need some or all of smtp.jar, pop3.jar and imap.jar.

I don't believe this is correct. I have only mail.jar and activation.jar in my classpath at runtime and this works fine for SMTP and IMAP. I expect it would work for POP as well. My understanding is that smtp.jar and so on are extracts from mail.jar that you can use if having smaller jar files is important to you.
