FJ310 EE5 - Developing Applications for the Java EE 5 Platform

Objetivo

• Describe the application model for the Java EE platform and the context for the model
• Develop and run an EJB technology application
• Develop a web-based user interface to an EJB technology application
• Develop simple web services for the Java EE platform
• Configure the Java EE platform services layer

Descrição

The Developing Applications for the Java EE Platform course provides students with the knowledge to build and deploy enterprise applications that comply with Java Platform, Enterprise Edition 5 (Java EE 5) technology standards. The enterprise components presented in this course include Enterprise JavaBeans (EJB) technology, the Java Persistence API (JPA), servlets, and JavaServer Pages (JSP) technology, web services, and the Java technology clients that use them. Students gain hands-on experience through labs that build an end-to-end, distributed business application. The labs explore session EJB components, which implement the Session Facade pattern and provide a front-end to entity components using the Java persistence API. The labs also explore message-driven EJB components, which act as Java Message Service (JMS) consumers. Students use web and Java technology clients to access Java technology-based enterprise services using servlets and pages created with JSP technology. Students are taught how to assemble an application from reusable components and how to deploy an application into the Java EE platform runtime environment. Students perform the course lab exercises using the NetBeans Integrated Development Environment (IDE).

Students who can benefit from this course
• Sun Certified Java technology programmers who want to develop enterprise applications that conform to the Java EE platform standards
• Java Enterprise developers who want to expand their skills with Java enterprise technologies
• Students interested in the Enterprise Java certifications:
o Sun Certified Business Component Developer
o Sun Certified Web Component Developer
o Sun Certified Web Services Developer
o Sun Certified Enterprise Architect
