Session Java EE 6. Object. javax. mail. Sessionpublic final class Sessionextends java. Object. The Session class represents a mail session and is not subclassed. It collects together properties and defaults used by the mail APIs. A single default session can be shared by multiple applications on the. Unshared sessions can also be created. The Session class provides access to the protocol providers that. Store, Transport, and related.

The ordering of entries in the resource files matters. If multiple. entries exist, the first entries take precedence over the later. For example, the first IMAP provider found will be set as the.
