The document outlines an agenda for a presentation on Servlet 3, Java configuration, Spring 3.2, properties, data sources, MyBatis 3, MongoDB, caching with Infinispan, and SiteMesh. It includes details on annotations and Java configuration for Servlets, Filters, properties configuration, data sources, MyBatis integration, MongoDB integration using a MongoTemplate, caching with Spring and Infinispan, and configuring SiteMesh decorators. The presentation concludes with a demo, Q&A section, and thanks.
