I am implementing IMAP into my scout project. I am following the step by step guide. However, when I call Mailservice.CreateImapAdapter() I run into some problems.

The line ImapAdapter myAdapter = new ImapAdapter(); throws the following exception
java.lang.ClassNotFoundException: javax.mail.AuthenticationFailedException cannot be found by org.eclipse.scout.rt.server_3.9.0.20130527-1025

I initially thought it was a an authentication issue, but on closer inspection it happens as soon as I call new ImapAdapter(). Interestingly, I can call AuthenticationFailedException x = new AuthenticationFailedException(); without problems. So it seems that I can load the javax.mail.AuthenticationFailedException

I am using eclipse kepler for scout v3.9.0
The javamail it is trying to load (I think) is javax.mail_1.4.0.v201005080615

Any ideas what the problem could be?

I think those classes use an "Endorsed Java Mail".

I can recommend you to read:
* IMAP Step-by-Step tutorial.
* Java setup for Scout Commiter

Let us know if this helps or if you need more information...

I didn't previously specifically add mail.jar to the installed JRE in eclipse. I added the jar to the jre/lib directory only. I can now successfully connect to the mail server. However, I briefly ran into another problem.

ProcessingException[ProcessingStatus[ERROR code=0 invoking / javax/mail/Store java.lang.LinkageError: javax/mail/Store]]

Caused by: java.lang.LinkageError: loader constraint violation: loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) previously initiated loading for a different type with name "javax/mail/Store"

This I resolved by removing javax.mail from the server manifest.

All working now. Thanks for the help
