Java Mail: NoSuchProviderException: No provider for SMTP

[#1]

Hi experts,

please can someone help my by the following error:

<b>NoSuchProviderException: No provider for SMTP</b>

public class SendJavaMail {
	
	private static String status;
	private static String status_transport;

	public static String generateMail() {
		
		Properties props = new Properties();
		props.setProperty("mail.smtp.host", "ServerName");
		props.setProperty("mail.smtp.auth" , "false");
		
		Session session = Session.getDefaultInstance(props);
		
		try {
		MimeMessage mMeassage = new MimeMessage(session);
		mMeassage.setSubject("Subject");
		mMeassage.setText("Hello");
		InternetAddress fromAddress =
		new InternetAddress("[email protected]");
		InternetAddress toAddress =
		new InternetAddress("[email protected]");

		mMeassage.setFrom(fromAddress);
		mMeassage.setRecipient(Message.RecipientType.TO,  
                                toAddress);
		Transport transport = session.getTransport("SMTP");
		status_transport = String.valueOf(transport);
		<b>transport.connect("ServerName", "", "");</b>
		transport.send(mMeassage);
		transport.close();
		status = "Mail verschickt";
			
		} catch (MessagingException e) {
		status = e.getMessage();
		try{
		<b>Transport transport = session.getTransport("SMTP");</b>
		status_transport = String.valueOf(transport);
		}
		catch(NoSuchProviderException pe){
		status_transport 
                                = "NoSuchProviderException: "+pe.getMessage();	
		}
			
		}
		status = "Status Transport: "+status_transport+" 
                                Status: "+status;
		return status;
	}
}

I think transport.connect("ServerName", "", "") is not correct and

Transport transport = session.getTransport("SMTP") I get the error:

NoSuchProviderException

Have anyone an idea? Thanks in advanve!

If i change:

<b>transport = session.getTransport("smtp");</b>

I get the error:

java.lang.NoSuchMethodError: com.sun.activation.registries.MailcapFile.getMailcapList(Ljava/lang/String;)Ljava/util/Map;

Hi,

Did you find the solution of your problem?

I am facing same problem while sending mail. I have imported three jar files:

1) mail.jar

2) activation.jar

3) smtp.jar

Still getting exception : <b>'javax.mail.NoSuchProviderException: No provider for SMTP '</b>

How did you solve your problem?

Thanks,

I solved the problem by an other way. I used a WebService which already exists in my company to send mails.

If you find an other solution please let me know.

you need to include References for mail.jar in portalapp.xml

Hi,

include mail.jar,activation.jar,smtp.jar and other mail jar files in your classpath .

See that only one version of this jar's added to the classpath.

Answer if usefull...... reward with points.

Hi SAP user,

have you added smtp.jar file to your project?? If you want to send mail to User's then you must have 3 jar files with you they are:

1) mail.jar

2) activation.jar

3) smtp.jar(present in java mail package)

For more info on sending mails, refer to this code:
