/**
 * 

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:

*
    *
  • *
  • mail.smtp.host - Hostname for outbound transport * connections. Defaults to localhost if not specified.
  • *
* *

This factory can be configured in a * <Context> element in your conf/server.xml * configuration file. An example of factory configuration is:

*
 * <Resource name="mail/smtp" auth="CONTAINER"
 *           type="jakarta.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>
