I am trying to send emails using spring 5.1.3.RELEASE and Tomcat 9.0.43 but having the below exception. I can see in Tomcat lib folder the libraries mail-1.4.7.jar and javax.mail-api-1.6.2.jar but due to some reasons the exception below is showing that it's trying to use a method signature not available in mail-1.4.7 but only in the version 1.5.6.
I tried exclusion tag in all the dependencies in my pom.xml without success and changing the order and I don't want to change tomcat libs to replace the mail-1.4.7.
Could you help me please. Is there a way to enforce the use of application libs instead of Tomcat libs or what am I missing please in my configuration/code below.

My mail sender bean looks like this:
@Bean(name = "mailSender")
public JavaMailSender mailSender() {
org.springframework.mail.javamail.JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
mailSender.setHost("localhost");
mailSender.setPort(25);
mailSender.setUsername("admin@gmail.com");
mailSender.setPassword("password");
Properties props = mailSender.getJavaMailProperties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.auth", "false");
props.put("mail.smtp.starttls.enable", "false");
props.put("mail.debug", "true");
return mailSender;
}
The sending method:
public boolean send(String sender, String receiver, String subject, String message) {
try {
SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
simpleMailMessage.setFrom(sender);
simpleMailMessage.setTo(receiver);
simpleMailMessage.setSubject(subject);
simpleMailMessage.setText(message);
mailSender.send(simpleMailMessage);
return true;
}catch(Exception e) {
e.printStackTrace();
return false;
}
}
