JB161 JBoss and EJB3 for Java Developers (JBoss y EJB3 para Desarrolladores Java) en Monterrey

Here students will learn what the powerful HTTP Session can be used for and how it can save time for your users by increasing the performance of your application.

This module extends your understanding of the Servlet by detailing it's lifecycle and further showing how one might tap into this by listening for lifecycle events and covers how to implement a servlet filter to process incoming and outgoing data.

Here we go into depth on the power of JSPs. We will discus Expression Language (or EL) which enables developers to make calls into their JavaBeans directly from their web pages and output the results in a very readable fashion.

We will also look at Tag Libraries and why one might use them? This module demonstrates some of the functions available in the Java Standard Tab Library (JSTL) and how to use them. We will write our own custom tags such that you will be able to extend the JSP programming model to meet your needs.

Building your web presence is important, but it can be dangerous as well. In this module we will visit some of the security pitfalls and show you how to avoid them in your own deployment. This includes discussion of locking down your system and protecting it with passwords as well as implementing HTTPS using your own security certificate.

This module will discuss the use of Java Server Faces (JSF). How and why would a developer use such a framework? What advantages does it offer in designing and building a clean, modular application? How will JSF technology help you reach broader, worldwide audiences? How does JSF yield more maintainable code and how can you extend its functionality to meet the needs of your business? These questions and more comprise are addressed here.

This module introduces the Java Persistence API (JPA), its value and how developers can take advantage of this leap forward in object-relational mapping (ORM).We will see why this technology is so exciting to the industry and what it can offer you. We will learn about how to properly map objects, what options are available for complex relationships (including inheritance - a strength of object-oriented programming) and will gain insight into how to make these decisions.

Entity lifecycle, query language, proper packaging and optimizations such as lazy fetch will also be discussed here. Additionally, developers will see how annotations, the modern and powerful Java language feature, helps to make developers more efficient as they do the same for their applications. However, XML overrides will not be ignored as they retain significant value even in this annotated world.

This module provides a basic introduction to Enterprise Java Beans. It explains the case for server-side components and the different types of Beans available: session, entity and message-driven beans. It presents how to author each of these in an EJB3 world.The student will learn how to specify a local and/ or remote POJI (plain old Java interface) for the simple POJO-based component.

It will introduce stateless session beans and stateful session beans, the relevant Java annotations to create EJB3 components, EJB3 packaging and deployment.

This section will provide an overview of the architecture and implementation of Java EE web services. The student will learn how to expose EJB3 and Servlet components to enable remote XML RPC invocations to these components. The student will learn the basic approach of integrating the JBoss application server with legacy enterprise middleware and .NET.
