J2EE: J2EE platform Development

Set of 6 CD-ROMs: $829

Provides detailed coverage of the Java 2 Enterprise Edition platform, by introducing the J2EE SDK. The course shows the technologies that make up the J2EE platform, such as Servlets, JavaServer Pages, Enterprise JavaBeans, and JDBC connectivity. The course outlines the different roles and responsibilities for developing enterprise applications using J2EE, and also what built-in services and technologies are provided to developer. Finally, you'll learn how to build a web application client that interacts with the J2EE platform using Servlets and JavaServer pages.

This course  will teach you to...

  • Understand how and where the J2EE platform provides support for enterprise applications.
  • Explain the different components that make up the J2EE platform, throughout the n-tier environment.
  • Expose the different services and technologies that are built into the J2EE platform that a developer can leverage within an enterprise application.
  • Link to and work with diverse clients on the client tier that interconnects to the J2EE platform.
  • Build application clients using Servlets, HTML, and JavaServer Pages that communicate through the J2EE platform.
  • Understand how to design enterprise java applications from the client tier to the middle tier, and finally to the enterprise information systems tier.
  • Combine business logic to build business objects through the use of Enterprise JavaBeans (EJBs).
  • Explain design considerations when building, deploying and maintaining EJBs within an enterprise application.
  • Provide access to corporate data from enterprise information system applications to you J2EE application, through the use of data access objects and JDBC connectivity.
  • Deploy and Package an enterprise application successfully.
  • Provide more strict customized business rules to an enterprise application through the use of transaction management.
  • Explain the security mechanisms provided in the J2EE platform, such as authentication and authorization, from the client tier right through to the data storage tier.
  • Understand the additional J2EE SDK tools to provide access to other services and technologies such as user and group management using the RealmTool.

Who should take this course? Programmers, Architects, and Development Managers responsible for creating enterprise applications using the Java Language.
