Spring Sending Email With Attachment

[Rudi28]

Hi Everyone,

I'm trying to get an example of using Spring Mail to run.

The example is composed of an one interface and two classes in the src directory as well as a configuration xml file:

IMailer.java

package com.test.mail;

import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;

public interface IMailer {

	public void SetSimpleMailMessage (SimpleMailMessage simpleMailMessage);

	public void setMailSender(JavaMailSender mailSender);

	public void sendMail(String greeting, String content);

}

Mailer.java

package com.test.mail;

import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.MailParseException;
import org.springframework.mail.javamail.MimeMessageHelper;

public class Mailer implements IMailer {

	private JavaMailSender 		mailSender;
	private SimpleMailMessage 	simpleMailMessage;

	@Override
	public void SetSimpleMailMessage(SimpleMailMessage simpleMailMessage) {
		this.simpleMailMessage = simpleMailMessage;
	}

	@Override
	public void setMailSender(JavaMailSender mailSender) {
		this.mailSender = mailSender;
	}

	@Override
	public void sendMail(String greeting, String content) {

		MimeMessage message = mailSender.createMimeMessage();

		try {
			MimeMessageHelper helper = new MimeMessageHelper(message, true);

			helper.setFrom(simpleMailMessage.getFrom());
			helper.setTo(simpleMailMessage.getTo());
			helper.setSubject(simpleMailMessage.getSubject());
			helper.setText(String.format(
					simpleMailMessage.getText(), greeting, content));

			FileSystemResource file = new FileSystemResource("C:\\log.txt");

			helper.addAttachment(file.getFilename(), file);
		}

		catch (MessagingException e) {
			throw new MailParseException(e);
		}

		mailSender.send(message);
		
	}

}

App.java - To run the example

package com.test.mail;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class App {

    public static void main( String[] args )
    {
    	ApplicationContext context = new ClassPathXmlApplicationContext("Spring-Mail.xml");
    	 
    	IMailer mailer = (IMailer) context.getBean("mailer");
        mailer.sendMail("Mr. SIRS", "This is some text content to test this application.");
    }

}

Spring-Mail.xml

		<property name="text">
		<value>
			<![CDATA[
				Dear %s,
				Mail Content : %s
			]]>
		</value>
	</property>
	</bean>

</beans>

I added the following jars to the Java Application: activation.jar, common-beanutils, commons-chain, commons-collections, commons-digester, commons-logging, commons-validator, log4j, mail.jar, servlet-api.jar, and spring.jar. Granted, some jars might not be needed.

When I try to run the example I get:

org.springframework.beans.factory.BeanCreationExce ption: error creating bean with name mailer defined in class pathSpring -Mail.xml. Initialization of bean failed; nested exception is org.springframework.beans.InvalidPropertyException : Invalid property ’simpleMailMessage’ of class com.test.mail.Mailer. No property simpleMailMessage found.

Any help is appreciated. Thank you.

Best regards,

Rudi

Check your source.

@Override
	public void SetSimpleMailMessage(SimpleMailMessage simpleMailMessage) {
		this.simpleMailMessage = simpleMailMessage;
	}

Although this is valid in .Net it isn't in java... get/set should start with lowercase.

Hi Marten,

Thanks for the comment. I appreciate your help.

Good catch. Definitely that was wrong. I changed the name
of the SimpleMailMessage setter to start with lower case:

	@Override
	public void setSimpleMailMessage(SimpleMailMessage SimpleMailMessage) {
		this.simpleMailMessage = simpleMailMessage;
	}

But the program still doesn't work. Now I get a NullPointerException.

Exception in thread "main" java.lang.NullPointerException
at com.test.mail.Mailer.sendMail(Mailer.java:32)
at com.test.mail.App.main(App.java:14)

The App.java:14 is the call to sendMail. The last line.

The Mailer.java:32 is the first line in the sendMail method. The line:
MimeMessage message = mailSender.createMimeMessage();

Have a nice day. Thanks in advance again for your help.

Best regards,

Rudi

Then there must be something wrong in your setup. Post the full stacktrace.

Hi Marten,

I got the example to work. I created a text file that the program attaches to the email and added some jars that the project needed.

The jars that I added were the servlet-api, and a few commons. I already
had the activation, mail, and spring jars.

Have a great day. Thank you very much for your help.

Best regards,

Rudi
