Here is my code for sending the mail

package com.markEffy.aggregator.util;
import com.sun.mail.util.MailSSLSocketFactory;

import java.util.Properties;

import javax.mail.Message;
 import javax.mail.MessagingException;

        private String[] sendTo = {""};

        private int msgBodyType;

        public EmailAgent (String sendToAddr, int msgType) throws Exception {
            this.sendTo[0] = new String(sendToAddr);
            this.msgBodyType = msgType;
            }
        public EmailAgent (String sendToAddr, String emailMsgTxt, String emailSubjectTxt) throws Exception {
            this.sendTo[0] = new String(sendToAddr);
            this.emailMsgTxt = emailMsgTxt;
            this.emailSubjectTxt = emailSubjectTxt;
            }

        }

                return;
            }

            int msgType = this.msgBodyType; 
            new EmailAgent(sendTo, msgType).sendSSLMessage(sendTo, emailSubjectTxt, emailMsgTxt,
                    emailFromAddress, sf);
            System.out.println("Sucessfully Sent mail to All Users");
        }

        public void sendSSLMessage(String recipients[], String subject,
                String message, String from , MailSSLSocketFactory sf) throws MessagingException {
            boolean debug = true;
            Properties props = new Properties();
            props.put("mail.smtp.host", SMTP_HOST_NAME);

            props.put("mail.smtp.socketFactory.class", SSL_FACTORY);
            props.put("mail.smtp.socketFactory.fallback", "false");

            Session session = Session.getDefaultInstance(props,
                    new javax.mail.Authenticator() 
                     {
                         protected PasswordAuthentication                   

                      getPasswordAuthentication() {
                            return new

            for (int i = 0; i < recipients.length; i++) {
                addressTo[i] = new InternetAddress(recipients[i]);
            }
            msg.setRecipients(Message.RecipientType.TO, addressTo);

            // Setting the Subject and Content Type
            msg.setSubject(subject);
            msg.setContent(message, "text/plain");

            Transport.send(msg);
       }
}

I have added mail.jar and activation.jar in the lib folder of tomcat.I am using eclipse with tomcat 7,jre 7 and struts2.The following console error came while sending mail through Java:

Could you at a little bit more implementation and project setup for us. It is really difficult to see what's happening just out of this stacktrace. – mle
I have added some more details. Can u please help? – user3681970
Obviously there is a version mismatch of your com.sun.mail.smtp.SMTPTransport class. Can you say, which version of mail.jar you are using? – mle
I am using javamail-1.4.7. – user3681970
Ok, here it is javamail 1.5.2, working without problems... can you look through your classpath and verify that no other mail-implementations are present, so that we can eliminate version conflicts. – mle

So, I have just tested your code here, works perfectly with the following two mailing artifcats com.sun.mail:javax.mail:1.5.2 and javax.mail:javax.mail-api:1.5.2 Always keep the api-part and the implementation-part of your mailing artifacts in sync. So either change the mailapi-1.5.2 to mailapi-1.4.7 or update the javamail impl from 1.4.7 to 1.5.2.

Read all of the answers in multiple versions of javamail jar causing NoSuchProviderException.

You can also modify your code to set the context class loader during send to fix this issue:

    Thread t =  Thread.currentThread();
    ClassLoader ccl = t.getContextClassLoader();
    t.setContextClassLoader(session.getClass().getClassLoader());
    try {
        Transport.send(msg);
    } finally {
        t.setContextClassLoader(ccl);
    }
