Java 5 Variable Arguments

This presentation demonstrates the use of variable arguments to:

• Use the new OutputStream.printf and String.format messages
• Wrap a Log4J logger with a variable argument API

Object Relational Mapping Technologies - A Demo Enhanced Survey of Hibernate, JDO, and EJB Entity Beans 3.0

This presentation compares and contrasts the features of three well known Object to Relatinal Mapping (ORM) frameworks with respect to Plain Old Java Objects (POJOs) - Hibernate, JDO and EJB v3.

In addition to slide presentation, each ORM technology will be demonstrated in Eclipse with a simple database example.

The comparison of the 3 technologies targets the following ORM features:

• Transparent Persistence
• Cascading Operations with Entity Relationships
• Entity Identity
• Attached / Detached Mapping States
• Transaction Demarcation
• Cross Cutting Persistence Concerns - Pooling, Caching, Locking, Eager/Lazy Loading
• Application Architecture with ORM POJO Technologies

Introduction to Aspect Oriented Programming

This is an interactive, example-based introduction to Aspect Oriented Programming(AOP). We will work through several code-based demonstrations meant to assist you in working out your own definition of AOP. You will be expected to be able to read Java code and interact in small groups to form theories about how the examples manage to go counter to your expectations.

Background material already exists for this presentation at: http://schuchert.wikispaces.com/AspectJ+Self+Study

Getting the most out of JBoss Application Server – It’s all in the Microkernel

Learn how to take advantage of the infrastructure provided by JBoss Application Server to make your enterprise application more flexible, more manageable, and more maintainable. This session will center on customizing the microkernel by snapping in your own hot-deployable services while removing others to build exactly the server to suite your needs. AOP and the new JBoss Microcontainer will be discussed as well.

EJB 3.0 – Has Spring Sprung a Leak?

Over the past several years, many enterprise Java developers have rejected Enterprise Java Beans (EJB) due to its complexity and weight and adopted lightweight solutions like Spring and Hibernate instead. In response to this shift, the JCP recently released the EJB 3.0 specification which considerably simplifies the previous specification, standardizes the ORM API in the form of the new Java Persistence API, and reduces the configuration headache by supporting Java annotations. This session will cover EJB 3.0 and the Java Persistence API and discuss if these new technologies are a suitable replacement for Spring + Hibernate based systems.

Copy & Paste – Java, JEE and C#, .NET are More Alike than You Might Think

Suitable for both Java and .NET developers, this non-biased session will discuss and demonstrate where Java, JEE, and C#, .NET are similar and where they are not. Learn how to apply your .NET skills to Java and vice versa. The session will include discussions on C# vs. Java syntax, EJB vs. .NET component models, ASP.NET vs. JSP/Servlets/JSF, as well as a look toward the future of each.
