Course Description
Description
The Developing Applications for the J2EE Platform course provides students with the knowledge to build and deploy enterprise applications that comply with Java 2 Platform, Enterprise Edition (J2EE) standards. The enterprise components presented in this course include Enterprise JavaBeans (EJB) technology, servlets, and JavaServer Pages (JSP) technology, 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 EJB components using container-managed persistence. 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 (JSP pages). Students are taught how to assemble an application from reusable components and how to deploy an application into the J2EE platform runtime environment.
Who Should Attend?
Sun Certified Java technology programmers, who want to develop enterprise applications that conform to the J2EE platform standards.
