Developing Applications for the J2EE Platform (WJB-310A)

ID kurzu : WJB-310A Trvanie kurzu : dni

The Developing Applications for the J2EEPlatform course provides students with the knowledgeto build and deploy enterprise applications that complywith Java 2 Platform, Enterprise Edition (J2EE)platform standards. The enterprise components presentedin 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 buildan end-to-end,distributed business application. The labsexplore session EJB components, which implement theSession Facade pattern and provide a front-end to entityEJB components using container-managed persistence. Thelabs also explore message-driven EJB components, whichact as Java Message Service (JMS) consumers. Students useweb and Java technology clients to access Java technology-based enterprise services using servlets andpages created with JSP technology (JSP pages). Studentsare taught how to assemble an application from reusablecomponents and how to deploy an application in the J2EEplatform runtime environment.THIS COURSE REPLACESWJB-310
