Web Component Development with Servlet and JSP Technology

Prerequisites:

Delegates should be able to:

- Write Java technology applications, demonstrating significant programming ability
- Integrate existing Java code (for example, reuse existing classes created by other team members)
- Design Java technology applications
- Functionally describe the benefits of an n-tier architecture
- Write a web page using HTML

Course Description:

JavaServer Pages (JSP page) technology and servlets are the key web-tier technologies defined in the Java Platform, Enterprise Edition (Java EE platform). The Web Component Development With Servlet and JSP Technologies course provides experienced developers of Java technology applications the knowledge and skills to quickly build web applications from JSP page and servlet technologies using the Sun Java System Application Server, and the Apache Struts framework.

Students are exposed to the current methods for analyzing, designing, developing,and deploying web applications with Java technologies. Lab exercises provide students with experience in constructing and deploying the small-to-medium scale web applications found in intranet and low-volume commercial sites. The course features the Java EE 5 technology, and uses the Java EE 5 SDK. The students perform the lab exercises using the NetBeans Integrated Development Environment (IDE) 5.5. This course is also an ideal method of preparing for the revised Sun Certified Web Component Developer (SCWCD) for Java EE 5 certification examination. However, an SCWCD candidate should also spend six months building web applications using the JSP page and servlet technologies before taking the exam.

Course Objectives

Upon completion of this course, students will be able to:

- Write servlets using the Java programming language (Java servlets)
- Create robust web applications using Struts, session management, filters, and database integration
- Write JSP pages
- Create easy to maintain JSP pages using the Expression Language, JSP Standard Tag Library (JSTL), and the Struts Tiles framework
- Create robust web applications that integrate Struts and JSP pages

Who Should Attend

Developers with skills equivalent to that of a Sun Certified Java Developer, who are creating web components (such as servlets and custom tags), can benefit. This is not a course for web page designers using Hypertext Markup Language (HTML), JavaScript technology, or other web presentation technologies.
