Problem using Javax.Mail API

Hi Experts,
I am using Javax.mail API to send an email through java application. But i am facing an issue when i am deploying the java application in SAP WAS.
I have assigned values in SMTP Host ,Port, and InternetAddress and deployed to WAS. But when i deploy this java class again in WAS with changing the values for SMTP Host ,Port and InternetAddress and putting in Properties object ,its always picking the values set at first time.
Can anyone tell me whats wrong with following code .
Properties prpt = new Properties();
if (host == null)
host=token[0];
prpt.put("mail.smtp.host",host);
prpt.put("mail.smtp.sendpartial", "true");
if (port == null)
port=token[1];
prpt.put("mail.smtp.port", port);
Session session1=Session.getDefaultInstance(prpt, null);
MimeMessage message=new MimeMessage(session1);
message.setFrom(new InternetAddress(emailId"));
Thanks in advance.

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
InitialContext ic = new InitialContext();
So I had written a method getInitialContext() as shown in the above piece of code,
but that too did not work.

You 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.

Setting Importance Level for a email message using javax.mail.* API

Setting Importance Level for a email message using javax.mail.* API
From what I understand we can set Flag on Email Message. How can we set Importance Leve: High/Low for an email message?
Thanks
Purvi

Most of the message Flags work only for IMAP mailboxes. POP3 supports only the DELETED flag. It must be understood that Javamail is a framework which provides all the features available in a standard mailing system. But whether or not a particular feature works is a functionality of the particular implementation being used.
Thus for example POP3 cannot differentiate read from unread messages in a mailbox though Javamail provides that feature.

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.)
HTH.

Error using javax.mail package

Hi,
I have included the package javax.mail.* in my code.I have downloaded
jaf 1.0.2 and javamail 1.1.3 from the Sun Microsystems website.
When i try to compile my code i get the error message:
com/voxspectrum/ccvox/EmailServer.java:55: cannot resolve symbol
symbol : class MimeMessage
location: class com.voxspectrum.ccvox.EmailServer
javax.mail.Message msg = new MimeMessage(session);
I am using JDK ver 1.3.1_02. What should i set my path and classpath as, if i am using javax.mail package?
Please could you help me out with this problem!

Hi Nisha
You need to include the path to the mail.jar and activation.jar files in your classpath.
How you do it depends on the OS you are running on
in Windows 95 /98 the easiest way is to edit the autoexec.bat file and add the settings to your already existing classpath statement i.e.
set CLASSPATH=%CLASSPATH%;C:\richard\javamail-1.3\mail.jar C:\richard\jaf-1.0.2\activation.jar
(excuse the word wrapping) then reboot
on Linux / Solaris edit the .profile file for your user and set the CLASSPATH variable to
CLASSPATH=$CLASSPATH:<pathtofile>/mail.jar:<pathtofile>/activation.jar
export CLASSPATH
and that should do it
Hope this helps

How to use Java Mail API in Unix

I am trying to write some code using Java mail API. I want to execute it in Unix. I downloaded the mail API to windows machine and ftped the mail.jar file to a Unix machine. Then I set the class path as below:
export CLASSPATH=$CLASSPATH:/home.../mail.jar
Then I tried to compile my Java program. The output is as below:
error: error reading /home.../mail.jar; invalid END header (bad central directory offset)
mail.java:1: package javax.mail does not exist
import javax.mail.*;
Can any one please help me out.

You should also include the "activation.jar" file that you obtained from
downloading the Java Activation Framework, in your CLASSPATH.
For example:
export CLASSPATH=$CLASSPATH:/urPath/activation/activation.jar
Besides, assuming you unzipped javamail-1_4_1.zip in home/download the following should work
export CLASSPATH=$CLASSPATH:home/download/javamail-1.4.1/mail.jar:.

Using java mail api without servlets, I ve sent an html mail. In that Ive specified action to the servlet. On click, it shows url as file:///C:/Documents%20and%20Settings/sirivanig/Local%20Settings/Temporary%20Internet%20Files/Content.IE5/CNFHMDIT/updatemailerform%5B2%5D.htm instead of www.servername.com/....
May I know the reason why it shows like this.
Do I ve to send htmlmail through servlet so that it does show proper url?

Possibly your mailer is restricting your access to URLs to prevent
various scams. Without the details, it's hard to know what's going
wrong.
Have you tried with a different mailer?

How to do SAVE AS DRAFT using java mail api

Hello,
I want to know how to do SAVE AS DRAFT using Java mail Api.
thanks

Hello,
I want to know how to do SAVE AS DRAFT using Java
mail Api.
thanksI don't think you can. That sounds like a feature of a mail client app itself. The Java mail API is for when you're ready to actually send the thing. Saving drafts is storing them somewhere like you would any other data; nothing to do with the mail API.

Can i use java mail APIs to read Unix mail

hi
can i use java mail APIs to read Unix mail?
Unix has "mail" command which can be used to access mails on the Unix system.
is it possible to execute mail & access unix mails remotely using POP/IMAP
thanks in advance

There are JavaMail providers that allow you to access the Unix mail spool files directly. Alternatively the standard JavaMail API can access a POP or IMAP server, if one is installed.

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 lot

hi 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

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);

Problems sending email using javax.mail.*

I need to send an email from an application I am working on. I am using the features of the javax.mail package to do so. In looking at the code I am unsure why this is not working. This is my first time using this package so it might be something silly I am missing so any of your thoughts are appreciated. The code is as follows:
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
public class EmailTester {
     public static void main(String[] args) {
          try {
               //Set the smtp address
               Properties props = new Properties();
               props.put("mail.smtp.host", args[0] );
               // get the default Session
               Session session = Session.getDefaultInstance(props, null);
               session.setDebug(true);
               // create a message for this session
               Message msg = new MimeMessage(session);
               // set the from and to address
               InternetAddress from =
                    new InternetAddress( args[1] );
               InternetAddress[] to = new InternetAddress[1];
               to[0] = new InternetAddress( args[2] );
               msg.setFrom(from);
               msg.setRecipients(Message.RecipientType.TO, to);
               // set the subject and content type
               msg.setSubject("subject");
               msg.setContent("this is my test email", "text/plain");
               // send the email
               Transport.send(msg);
          catch (MessagingException me) {

I have an EMail class that I use at:
http://www.discoverteenergy.com/files/EMail.java
Feel free to use it or compare against your code to see what is different.
