It looks like your provider config files are not found at runtime.
Excerpt from the JavaMail Spec:
> The providers for JavaMail APIs are configured using the following files:
> n javamail.providers and javamail.default.providers
> n javamail.address.map and javamail.default.address.map
> Each javamail.X resource file is searched in the following order:
> 1. java.home/lib/javamail.X
> 2. META-INF/javamail.X
> 3. META-INF/javamail.default.X

Maybe you should try to list the valid providers with
getProviders().
