Enterprise JavaBeans and J2EE™

Duration: 5 days | Price: Contact HOTT for pricing.

Students Will Learn:
  • How to write Session, Message-Driven and Entity Beans
  • EJB 3.0 Simplified APIs
  • EJB 3.0 Java Persistence API
  • EJB Security and Transaction Management
  • JAX-WS Web Services
  • Java EE Web Application Architecture
  • Developing Servlets & JSPs
  • Developing and Deploy JSP Tag Libraries

Description: This hands-on course provides participants with the knowledge and experience required to develop and deploy Enterprise JavaBeans, Web Services and robust Java EE (Java Enterprise Edition) web applications. The focus of the course is on building components that are deployed to the EJB Container and building web-enabled applications that employ Servlets, JavaServer Pages and Tag Libraries to exploit the services provided by the Java EE platform. This course covers architectural design issues as well as specific coding models for Java EE components, and is up to date with the latest Java EE 5, EJB 3, JAX-WS 2.1, JSP 2.1 and Servlet 2.5 specifications. Security, transaction management, inter-component communication and deployment issues are discussed in detail, with hands-on labs to solidify understanding.

Since coding and deployment files are standardized by the Jave EE specifications, students may readily apply the skills learned in this class to write code for any compliant server, including Apache Tomcat, JBoss, WebSphere, Oracle, WebLogic and many others. Students will understand the role and architecture of the most important containers in the Java EE specification: the Web Container (which hosts HTML pages, Servlets and JSP Pages) and the EJB Container (which hosts Enterprise JavaBean components). Participants will learn how to use important Java EE services and protocols including JNDI, JDBC and JMS. Students will learn how to utilize ANT, a flexible and powerful XML-based build utility, to compile, deploy and execute stand-alone and enterprise Java applications. Comprehensive hands-on lab exercises reinforce instructor lectures and build direct competence in the topics presented throughout the course.

Prerequisites: Java SE 5 programming experience and an understanding of object-oriented design principles. Fundamental knowledge of XML is helpful but not required.
