Provider for jakarta.activation.spi.MimeTypeRegistryProvider cannot be found

Question

After having to change from javax.mail to jakarta.mail, my application fails to start because of "Provider for jakarta.activation.spi.MimeTypeRegistryProvider cannot be found". What is a MimeTypeRegistryProvider, and how can I add one?

Answer 1

AddAngus Mail Provider to your classpath.

For maven, add the following dependency to your pom.xml

<dependency>
  <groupId>org.eclipse.angus</groupId>
  <artifactId>angus-mail</artifactId>
</dependency>

Answer 2

You need to add the angus-activation-1.1.0.jar and angus-mail-1.1.0.jar packages.
