Comphrensive JavaServer Pages Training

Posted on by

This four-day course develops skills in JavaServer Pages, or JSP, which is the standard means of authoring dynamic content for Web applications under the Java Enterprise platform.  It treats JSP 2.0, including older features such as scriptlets but focusing on newer features and techniques, including JSP expressions and the JSTL.  At the end of the course, students will be well prepared to author JSPs for small- or large-scale Web applications, either “by hand” (they use only a text editor in class) or using an authoring tool.

The first module begins with an introduction of Web applications in general, shows how Java servlets and JSPs establish a framework for writing Web applications, and then covers JSP 2.0 features in detail, from scripting elements to use of dedicated JavaBeans to JSP expressions, and quick introductions of JSTL and custom tag development.

By the end of the module students will be able to create their own JSP applications, including interactive applications using HTML forms and pages that perform fairly complex processing using scripts and or actions.  Although scripting is covered, the scriptless authoring style encouraged by the JSP 2.0 specification is emphasized, and students will be well equipped to develop concise and effective JSP applications.

The second module covers the JSTL, or JSP Standard Tag Library, actually a set of four custom tag libraries that establish a portable standard for common processing tasks in JSP.  JSTL is a major part of the new scriptless authoring style encouraged (and enabled) by the JSP 2.0 specification.  This module covers all four JSTL libraries in depth:

 

Each individual tag in each library is covered, with precise syntactic rules shown in a standard format in the student guide, and JSTL techniques and best practices are discussed for each library.  An extensive set of example applications illustrates common usage of each major group of actions, and the module culminates with a wrap-up workshop that brings core, SQL, and XML techniques to bear in a single application.

Goals

  • Explain the fundamentals of HTML and HTTP in the World Wide Web.
  • Describe the CGI and its role in implementing interactive Web applications.
  • Describe JavaServer Pages and their relationship to servlets and J2EE generally.

  • Explain the use of directives on JSPs and outline the principal directives.
  • Implement simple JSPs that use Java code in declarations, expressions and scriptlets.
  • Enumerate and use the implicit objects available to scripting elements.
  • Explain the use of HTML forms in Web applications.
  • Implement an interactive Web application using JSP.
  • Use Java exception handling and JSP error pages to handle errors in JSP applications.

  • Manage cookies to store client-specific information at various scopes and durations.
  • Explain the use of JavaBeans in JSP and their role in enhancing the separation of business logic from page design.
  • Use Beans to implement effective interactive JSP applications.
  • Describe the use of the JSP expression language in simplifying dynamic page output.
  • Write JSP expressions and implement JSPs that use them in favor of scripts.
  • Describe the role of the JSP Standard Tag Library in JSP development.
  • Implement JSPs that use basic JSTL actions to simplify presentation logic.
  • Describe custom tags in JSP and explain how they are implemented, both using Java and JSP itself, and how they are used.
  • Discuss threading issues in JSP and describe the use of directives to control how threading is handled.
  • Describe the various uses of XML in JSP applications.
  • Deploy a logical Web application to a Web server in a WAR file.
  • Describe the use of the JSP expression language to simplify dynamic page output.
  • Write JSP expressions and implement JSPs that use them in favor of scripts.
  • Implement JSPs that use basic JSTL actions to simplify presentation logic.
  • Decompose a JSP application design into fine-grained, reusable elements including JavaBeans, custom tag handlers and tag files that use JSTL.
  • Use core JSTL actions to complement standard actions, custom actions, and JSP expressions for seamless, script-free page logic.
  • Direct conditional and iterative processing of page content by looping through ranges of numbers, over elements in a collection, or over tokens in a master string.
  • Import external resources by URL for processing, or redirect the JSP container to an external resource to handle the current request.
  • Set locale and time zone information in JSPs, and use them to correctly format numbers, dates and times for all clients.
  • Use resource bundles to manage application strings, and produce the appropriate strings at runtime for a particular client locale.
  • Locate a data source, query for relational data, and parse result sets.
  • Perform updates, inserts and deletes on relational data using SQL actions.
  • Manage queries and updates in transaction contexts.
  • Parse XML content from a variety of sources.
  • Derive information from parsed XML content using XPath expressions.
  • Implement conditional processing and loops based on XML information.
  • Apply XSLT transformations to XML content.
  • Implement a simple Web service that reads and writes SOAP.
