JMS

Yêu cầu : 

 TechSchool Solutions designs software systems for schools. One of the problemsthat the schools face is teacher absenteeism or teachers taking leaves on a short  notice. The schools find it difficult to call substitute teachers in such a short time. TechSchool Solutions is planning to build a system which would enable the school teachers to request for leaves using the school portal. The system would then send an e-mail to all the substitute teachers that have been registered in the system. As a member of the development team, you are required to build the JMS-based module. Your tasks involve developing a session bean that acts as a message listener and receives a message from the JMS queue whenever a teacher puts in a leave request. The session bean, then calls other modules that handle rest of the processes.
