Spring JavaMailSenderImpl javax.mail.NoSuchProviderException: smtp

Question

I have a very large project with tons of dependencies, and when I try to send mail, I get the following exception:

javax.mail.NoSuchProviderException: smtp

I know that the code works because it is part of the library that is used in other projects. Does anyone know what might cause this exception? I looked through the entire jar, and the only one containing "javax.mail" was mail-1.4.4-SNAPSHOT.jar.

Is there a file / class that logs the smtp protocol, and this could happen somewhere else in my classpath?

Answer 5

, mailapi.jar .

I recently updated the project to use the PayPal soap API, and the PayPal distribution had a mailapi.jar file that was different from the one I had in my project and caused my application to fail when sending mail.

So, for me, I just had to go back to my old mailapi.jar, and I was fine.

Answer 6

I had it now. The problem was two javax.mail.jar in the same classpath.
