我已经在WebLogic Server版本：12.2.1.0.0中创建了一个邮件会话，但是当我启动服务器时，出现此错误：
Unable to find Session in JNDI location mail/tdk/main
weblogic.application.ModuleException: javax.naming.NameNotFoundException: While trying to lookup 'mail.tdk/main' didn't find subcontext 'mail'. Resolved ''; remaining name 'mail/tdk/main'
