SL-314: Web Component Development With Servlet and JSP Technologies 

Duration 5 Days
 
The Web Component Development with Servlet and JSP Technologies course provides students with the knowledge and skills needed to quickly build reference implementation-compliant Web tier components from JavaServer Pages (JSP) and Java Servlet extensions using the Tomcat server environment. Students are exposed to the current best practices for analyzing, designing, developing, testing, and deploying Web applications with Java technologies. Real-world lab exercises provide students experience with constructing and deploying small- to medium-scale Web applications found in intranet and low-volume commercial sites.

This course also provides an ideal method of preparing for the new Sun Certified Web Component Developer certification examination. As such, students are not only taught the technical details of JSP and servlet technology, they also learn about the best practices for integrating the Web tier with the other tiers, from the browser display to Enterprise JavaBeans (EJB) components running on an application server and back-end database resources.

 Who Can Benefit

Java programming language developers with skills equivalent to that of a Sun Certified Developer for the Java 2 Platform who are creating Web components, such as servlets and custom tags, used in the assembly and generation of dynamic web content. This is not a course for Web page designers using Hypertext Markup Language (HTML), JavaScript, or other web presentation technologies.

 

Prerequisites

To succeed fully in this course, students should be able to:
  ? Write Java technology applications, demonstrating significant programming ability
  ? Integrate existing Java technology code (that is, 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
 

Skills Gained

Upon completion of this course, you should be able to:
  ? Select the best Web technology for an application and architecture
  ? Write Java servlets
  ? Connect a Web application to EJB components and databases
  ? Implement application management techniques, such as security and threading
Code JSP pages
  ? Create custom tag libraries for JSP pages
