Not able to send mail in a Maven/Spring project (with otherwise working code)

[Rohit Mehta]

Hi all, I am using java 6.0, Spring 3.0 & Maven. I am facing a strange problem.

I am trying to send mail from my application, but not able to do so. I checked with debug on, the logs seems fine - no exception/error but the mail doesn't trigger.

public class JavaEmail 
{
	private final String SMTP_AUTH_USER = "[e-mail]";
	private final String SMTP_AUTH_PWD  = "secret";
	
	public void sendMain(String strFrom, String strTo, String strSubject, String strContent) throws MessagingException 
	{
		Message message = new MimeMessage(getSession());

		message.addRecipient(RecipientType.TO, new InternetAddress(strTo));
		message.addFrom(new InternetAddress[] { new InternetAddress(strFrom)});

		message.setSubject(strSubject);
		message.setContent(strContent, "text/plain");

		try {
			Transport.send(message);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	private Session getSession() {
		Authenticator authenticator = new Authenticator();

		Properties properties = new Properties();
		properties.setProperty("mail.smtp.submitter", authenticator.getPasswordAuthentication().getUserName());
		properties.setProperty("mail.smtp.auth", "true");

		properties.setProperty("mail.smtp.host", "smtp.myorg.com");
		properties.setProperty("mail.smtp.port", "25");
		properties.setProperty("mail.debug", "true");

		return Session.getInstance(properties, authenticator);
	}

	private class Authenticator extends javax.mail.Authenticator 
	{
		private PasswordAuthentication authentication;

		public Authenticator() 
		{
			String username = SMTP_AUTH_USER;
			String password = SMTP_AUTH_PWD;
			authentication = new PasswordAuthentication(username, password);
		}

		protected PasswordAuthentication getPasswordAuthentication() 
		{
			return authentication;
		}
	}
	
	
	public static void main (String [] args) throws MessagingException {
		
		JavaEmail email = new JavaEmail();
		
		email.sendMain("[e-mail]", "[e-mail]", "Say Hi ..", "Body");
		
	}
	
}

I have tried with other sample programs as well - with or without spring configurations. No error. BUT no mail as well.

IMP - same program(s) work fine if I use them in my other project which doesn't use maven - but otherwise have same configurations. In those logs there are some more lines in between ..

Have tried other samples from net as well, but no luck. Seems Maven is not OK with something. Any suggestions are welcome.

How are you running the program?

[Rohit Mehta]

From different points - main() within class, outside class & through application logic flow. From everywhere - the logs are same (without those 4/5 lines as mentioned - otherwise smooth) - but no mail.

If you'll notice, your message body on the failing email is ".".

Actually, that's a little suspicious, since you'd generally terminate an interactive email body with a single line with a "." on it, but I don't think that's supposed to apply here.

One thing that my be an issue, however, is that there are actually 2 jars required to send email. One is the jar with the javax.mail packages, the other is the activation.jar. It may be that activation.jar isn't getting pulled in.

Here's something that might help:

Thanks Tim for your reply. Actually it was not due to "not finding jar" but due to "over finding" of jars.

Don't know how, but somehow from other dependencies - these two (& other geronimo*) jars were pulling & these two were causing issue:

geronimo-activation_1.1_spec-1.0.1.jar
geronimo-javamail_1.4_spec-1.2.jar

I excluded them - & all is well.

<plugin> <artifactId>maven-war-plugin</artifactId> <version>2.1.1</version> <configuration> <packagingExcludes>WEB-INF/web.xml,WEB-INF/lib/geronimo-activation_1.1_spec-1.0.1.jar,WEB-INF/lib/geronimo-javamail_1.4_spec-1.2.jar</packagingExcludes> <warName>SCTM_Retailer</warName> </configuration> </plugin>

Actually, you should have gone the other direction. The javamail facility is a standard component of J2EE, if I'm not mistaken, so all the full-stack servers have it, though the partial implementations such as Tomcat and Jetty do not.

You can include the standard javamail API with scope "provided" and build a WAR that should then properly run in Geronimo using the Geronimo facilities.

If you need to be able to test under Tomcat, you can set up separate Tomcat and Geronimo profiles so that the appropriate references are made for the desired target server.
