list of Subscription application that is timely and very important to the daily finance
business model. Only entitled users can access this system. Servlets, EJB (deployed in
Weblogic) interact with data layer using LDAP server resource pool and generate content
and control views. Users are entitled/de-entitled bi-monthly by Autosys batch job. Admin
tools are been used to check status/entitle/de-entitle/subscribe users. Stored procedures
are created to perform such functions.
