J2EE application architectures
course overview
This is a one-day course that covers the collaborations between the elements of the J2EE platform. In particular, how JSP and Servlet-based Web applications link with enterprise components in EJB. Practicals focus on the design of J2EE applications.
Duration: 1 days
objectives
- uncover the essentials of the Java solution to building n-tier applications
- design various application architectures based on the J2EE platform
- show the role of Java Web and enterprise technologies - Servlets, JSP, JNDI, and EJB
- demonstrate the basic mechanics of J2EE technology
- code interactions between Java Web components and enterprise components — uncover the essentials of the Java solution to building n-tier applications
- design various application architectures based on the J2EE platform
- show the role of Java Web and enterprise technologies — Servlets, JSP, JNDI, and EJB
- demonstrate the basic mechanics of J2EE technology
- code interactions between Java Web components and enterprise components
target audience
The course is suitable for software developers and designers familiar with Java.
prerequisites
Ideally this course would be preceded by: design and develop Java applications; and followed by either or both of: develop EJB components, and develop Web applications with JSP and Servlets.
