Problem using Java Mail API with WLS 7.0
Hi All,
I am trying to use the Java Mail API provided by WLS 7.0. I have made the
settings metioned in the WLS 7.0 docs. However when I try to run the program I
am getting the following error:
javax.naming.NoInitialContextException: Need to specify class name in environment
or system property, or as an applet parameter, or in an application resource file:

Can anyone please tell me what is the problem. I thought that we cannot directly
do

So I had written a method getInitialContext() as shown in the above piece of code,
but that too did not work.
Eagerly awaiting a response.
Jimmy ShahYou can use InitialContext ic = new InitialContext() only if you are using a startup class, servlet or a JSP i.e
server side code.
If you are using a java client you need to use Context ic = getInitialContext();
Try this code
import java.util.*;
import javax.activation.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.naming.*;
import java.io.*;
import java.net.InetAddress;
import java.util.Properties;
import java.util.Date;
public class MailTo {
public static void main(String args[])
try {
Properties h = new Properties();
h.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
h.put(Context.PROVIDER_URL, "t3://localhost:7001");
Context ic = new InitialContext(h);
Session session = (Session) ic.lookup("testSession");
Properties props = new Properties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.host", "XX.XX.XX.XX");
props.put("mail.from", "[email protected]");
Session session2 = session.getInstance(props);
Message msg = new MimeMessage(session2);
msg.setFrom();
msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse("[email protected]",false));
msg.setSubject("Test Message");
msg.setSentDate(new Date());
MimeBodyPart mbp = new MimeBodyPart();
mbp.setText("This is a mail sent to you using JAVA Mail API and Weblogic Server");
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp);
msg.setContent(mp);
Transport.send(msg);
catch(Exception e)
e.printStackTrace();
}//end of main
}//end of class
We have shipped a javamail example in the samples\server\src\examples\javamail folder.

Problem in sending messages using java mail api
Hi All,
I have a problem in sending messages via java mail api.
MimeMessage message = new MimeMessage(session);
String bodyContent = "ñSunJava";
message.setText (bodyContent,"utf-8");using the above code its not possible for me to send the attachment. if i am using the below code means special characters like ñ gets removed or changed into some other characters.
MimeBodyPart messagePart = new MimeBodyPart();
messagePart.setText(bodyText);
// Set the email attachment file
MimeBodyPart attachmentPart = new MimeBodyPart();
FileDataSource fileDataSource = new FileDataSource("C:/sunjava.txt") {
public String getContentType() {
return "application/octet-stream";
attachmentPart.setDataHandler(new DataHandler(fileDataSource));
attachmentPart.setFileName(filename);
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messagePart);
multipart.addBodyPart(attachmentPart);
message.setContent(multipart);
Transport.send(message);is there any way to send the file attachment with the body message without using MultiPart java class.Taken pretty much straight out of the Javamail examples the following works for me (mail read using Thunderbird) // Define message
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
// Set the 'to' address
for (int i = 0; i < to.length; i++)
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
// Set the 'cc' address
for (int i = 0; i < cc.length; i++)
message.addRecipient(Message.RecipientType.CC, new InternetAddress(cc[i]));
// Set the 'bcc' address
for (int i = 0; i < bcc.length; i++)
message.addRecipient(Message.RecipientType.BCC, new InternetAddress(bcc[i]));
message.setSubject("JavaMail With Attachment");
// Create the message part
BodyPart messageBodyPart = new MimeBodyPart();
// Fill the message
messageBodyPart.setText("Here's the file ñSunJava");
// Create a Multipart
Multipart multipart = new MimeMultipart();
// Add part one
multipart.addBodyPart(messageBodyPart);
// Part two is attachment
for (int count = 0; count < 5; count++)
String filename = "hello" + count + ".txt";
String fileContent = " ñSunJava - Now is the time for all good men to come to the aid of the party " + count + " \n";
// Create another body part
BodyPart attachementBodyPart = new MimeBodyPart();
// Get the attachment
DataSource source = new StringDataSource(fileContent, filename);
// Set the data handler to this attachment
attachementBodyPart.setDataHandler(new DataHandler(source));
// Set the filename
attachementBodyPart.setFileName(filename);
// Add this part
multipart.addBodyPart(attachementBodyPart);
// Put parts in message
message.setContent(multipart);
// Send the message
Transport.send(message); -
Problem in retrieving email using java mail api
hi,
In my project,i am retrieving mails from a particular email id.
I am able to retrieve the latest mails and save it in a folder in my system.
The problem is whenever i run the program eventhough the most recently received mail in inbox is retrieved and saved,again it is retrieving the same one and saving it in the same folder(not repeating).
I tried to check the newmessages in the inbox using the folder.hasNewMessage() method in java mail api,but the method is returning false only regardless new mail is there in inbox or not.
I want to read the unread messages only.Dont want to retrieve the already read mails.
I got the mail retrieving code from the below site.(sorry not posting the code because it is so long and having 4 classes)
http://www.builderau.com.au/program/java/soa/Getting_the_mail_in_receiving_in_JavaMail/0,39024620,39228060,00.htm
Can anyone tell me how to read unread mails in the inbox?
Thanks a lothi parvathi
i think your mail program is receving mails using imap
the imap is only receve the mail from server but the pop is deleting the mails after receving
use the following sample code
package com.sfrc.mail.pop;

import javax.mail.internet.*;
import com.sun.mail.handlers.message_rfc822;

Using Java Mail API from Tomcat
Hello,
Purely as an academic exercise I have written a JSP page which, upon being requested from the client's browser, should send me a default email using Java Mail Api.
here is the code :
import java.util.*;
import java.io.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class TestMail {
static String msgText1 = "success this time 12";
static String msgText2 = "This is the text in the message attachment.";
public String sendIt() {
String to = "<my email";
String from = "<anything>";
String host = "<my ip address of smtp server>";
boolean debug = false;
Properties props = new Properties();
props.put("mail.smtp.host", host);
Session session = Session.getInstance(props, null);
.....The code works fine as a stand alone app but when called from JSP page it hangs on the Session.getInstance line. I can only guess that this might be a security issue with the container not allowing access to the smtp server ?
Can anyone give me a clue ???Your Tomcat log files should spell out the problem for you.
My Tomcat installation does not come with the Java Mail API. I had to add the mail and activation jar files to the server/common.lib directory (or the server's shared/lib or the WEB-INF/lib of your application.)

}END OF PART 2
END OF PROGRAM 2
P.S: CHECKING !!
STEP 1.
First compile and execute the PROGRAM 1 with your USERNAME & PASSWORD. This will send a mail to your own account.
STEP 2.
Now compile both PART 1 & PART 2 of PROGRAM 2. Then, execute PART 1 - Main.java. This will retrive the mail sent in step 1. njoy! :)
In future, I hope this is added to the demo programs of the Java Mail API download package.
This is for 3 main reasons...
1. To prevent a lot of silly questions being posted on this forum [like the ones I did :(].
2. To give the first time Java Mail user with a real time working example without code modification [code has to use command line args like the demo programs - for instant results].
3. Also, this is what google has to say..
"The Gmail Team is committed to making sure you always can access your mail. That's why we're offering POP access and auto-forwarding. Both features are free for all Gmail users and we have no plans to charge for them in the future."
http://mail.google.com/support/bin/answer.py?answer=13295
I guess bshannon & Java Mail team is hearing this....
Again, Hurray and thanks for helping me make it!! cheers & no more frowned faces!!
(: (: (: (: (: GO JCODERS GO!! :) :) :) :) :)

Error while sending mail when using Java Mail API
Hi Experts,
I am trying to execute a webdynpro application which uses the Java Mail API to send emails. The exception that I get on executing the application is :
Sending failed; nested exception is: javax.mail.SendFailedException: Invalid Addresses; nested exception is: javax.mail.SendFailedException: 550 5.7.1 Unable to relay for [email protected]
Can anybody please help me sort out the issue.
Regards
AbdullahHi,
Usually one get this error if the SMTP server is configured not to relay mails (a security measure) or the SMTP server need the mail to be sent from a trusted IP or with proper authentication. Some SMTP servers are configured to block junk mails.
Pls check with your mail server administrator.

Java mail api: SendFailedException when trying to send Mail via SMTP
Hello,
I'm trying to send a mail via java mail api using a server that requires smtp authentication.
I'm currently using the following code:
protocol = "smtp";
host = "auth.smtp.profimailer.de";
port = 25;
String from="[email protected]";
String to="[email protected]";
props.put("mail.smtp.host", host);
props.put("mail.smtp.auth", "true");
Authenticator auth = new PopupAuthenticator();
session=Session.getInstance(props,auth);
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from,"[email protected]"));
message.addRecipient(Message.RecipientType.TO,new InternetAddress(to,"ToName"));
message.setSubject("Hello JavaMail");
message.setText("Welcome to JavaMail");
Transport.send(message);
static class PopupAuthenticator extends Authenticator {
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("e12345676", "mypass");
}When trying to run this code, I get the following exception:

Any suggestions on this?
Thanks and best regards,
JensHi,
yes smtp is a standard and I think you could use this with almost every smtp server.
If your smtp server doesn't require authentication you can access it without an authenticator
I think...
Best regards,
