A new age of JVM is upon us. JVM is no longer just for Java. As Groovy, Jython, and JRuby has proved, there is life for other languages on the JVM. Scala is different than most of the other popular JVM alternative languages. We’ll explore the origin, intent and the philosophy of the Scala programming language. The unique combination of OOP and Functional programming will be presented. Major features of Scala such as actors, type inference and Java integration will also be discussed.

Abstract Relational databases are relational and Java is object-oriented. Object Relational Mapping (ORM) is what helps bridge the gap. The Java Persistence API (JPA) focuses on helping developers easily get data in and out of databases without having to interact with the cumbersome JDBC API. This presentation will discuss how to develop applications using JPA, the assumptions, abilities, limitations, the different implementations available as well as alternatives.
Objectives: - Simple Entity and O/R mapping - The EntityManager API and the lifecycle management - How to map relationships between tables in a database-agnostic way. - How to map inheritance hierarchies. - How and when to use the EJB QL -We'll discuss how to configure, package and deploy a JPA application using XML and/or annotations.
Bio Judes Tumuhairwe is a developer and entrepreneur. He is founder of the micro-ISV Tooro Systems. When he is not working at Ford Motor Company as a J2EE consultant, he's at home developing J2EE applications or participating on open-source mailing lists. Before Ford, he worked at the Wisconsin DOJ building a law enforcement application. He's currently developing an online payment system with JBoss Seam and EJB3, JPA/Hibernate using JSF (Richfaces) and Facelets on JBoss. He enjoys reading books on software development and entrepreneurship.
