I'm trying to set up my Java project to be able to send e-mail (via g-mail, if it matters) and am getting "javax.mail.NoSuchProviderException: No provider for smtps" every time I try to run the following line (which is copy/paste from their example).
Transport transport = session.getTransport("smtps");
I've looked around and found that this is generally thrown because you don't have the mail.jar included in your classpath, but I do in fact have the mail.jar included. Since I am running JDK 1.6 I do not need to include the activation.jar according to the FAQ here (http://www.oracle.com/technetwork/java/javamail/faq-135477.html#classpath). Further, the activation.jar does not seem to be present in version 1.4.7 of javamail.
Just in case something got corrupted, I re-downloaded the entire zip from oracle's website, extracted it and added the jar fresh (after deleting the old jar) and I am still getting the same error. Any thoughts as to what the issue could be at this point?
EDIT: Here is the full stack trace that is being printed:
javax.mail.NoSuchProviderException: No provider for smtps
at javax.mail.Session.getProvider(Session.java:433)
at javax.mail.Session.getTransport(Session.java:627)

So it turns out that the issue was that an outdated version of mail.jar was included in a project that I was referencing and, upon updating that copy of the mail.jar, the issue was resolved.
For future reference, is there any way to log or provide visibility on such jar conflicts?
