NoClassDefFoundError for javax.mail.Message while posting mail

Hi All,

i have created a background callable object to send mails where I am using following code :-

import java.util.Collection;
import java.util.Iterator;
import java.util.Locale;
import java.util.Properties;

import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public boolean postMail(String[] p_to, 
						String[] p_cc, 
						String[] p_bcc, 
						String p_subject, 
						String p_from, 
						String p_message) {

		//Set the host smtp address
		Properties props = new Properties();
		props.put("", "<portal smtp host ip>");		
		Session session = Session.getDefaultInstance(props);
		// create a message
		Message msg = new MimeMessage(session, null);

		// set "From" 
		InternetAddress addressFrom = new InternetAddress(p_from);

		//Set "To"
		InternetAddress[] addressTo = new InternetAddress[p_to.length];
		for (int i = 0; i < p_to.length; i++)	{
			addressTo<i> = new InternetAddress(p_to<i>);
		msg.setRecipients(Message.RecipientType.TO, addressTo);
		//Set "CC"
		InternetAddress[] addressCC = new InternetAddress[p_cc.length];
		for (int i = 0; i < p_cc.length; i++)	{
			addressCC<i> = new InternetAddress(p_cc<i>);
		msg.setRecipients(Message.RecipientType.CC, addressCC);
		//Set "BCC"
		InternetAddress[] addressBCC = new InternetAddress[p_bcc.length];
		for (int i = 0; i < p_bcc.length; i++)	{
			addressBCC<i> = new InternetAddress(p_bcc<i>);
		msg.setRecipients(Message.RecipientType.BCC, addressBCC);
		//Set the "Subject" 
		//Set Message and Message Type
		msg.setContent(p_message, "text/plain");
		//Send mail over the SMTP
	}catch (Exception e) {
		// TODO: handle exception
	return false;			

But when i am executing this CO, I get java.lang.NoClassDefFoundError for javax.mail.Message.

Can anybody help me with this?

Thanks and regards,

Amey Mogare

    Hi Amey,

    i guess the solution was the missing reference ?

    What do you have to use for the mail jar ?

    • Actually, mail.jar, activation.jar were not deployed on server...I only created and added compilation public part of this external library DC. But later I figured this out and created-n-added assembly public part to a J2E server component Library DC and deployed it.

      Then it worked successfully.

      Thanks and regards,
