| /** |
| * <p>Factory class that creates a JNDI named JavaMail Session factory, |
| * which can be used for managing inbound and outbound electronic mail |
| * messages via JavaMail APIs. All messaging environment properties |
| * described in the JavaMail Specification may be passed to the Session |
| * factory; however the following properties are the most commonly used:</p> |
| * <ul> |
| * <li> |
| * <li><strong>mail.smtp.host</strong> - Hostname for outbound transport |
| * connections. Defaults to <code>localhost</code> if not specified.</li> |
| * </ul> |
| * |
| * <p>This factory can be configured in a |
| * <code><Context></code> element in your <code>conf/server.xml</code> |
| * configuration file. An example of factory configuration is:</p> |
| * <pre> |
| * <Resource name="mail/smtp" auth="CONTAINER" |
| * type="javax.mail.Session"/> |
| * <ResourceParams name="mail/smtp"> |
| * <parameter> |
| * <name>factory</name> |
| * <value>org.apache.naming.factory.MailSessionFactory</value> |
| * </parameter> |
| * <parameter> |
| * <name>mail.smtp.host</name> |
| * <value>mail.mycompany.com</value> |
| * </parameter> |
| * </ResourceParams> |
| * </pre> |
