Class Description

Class Overview

Class Goals

• 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.

Class Materials

Each student in our Live Online and our Onsite classes receives a comprehensive set of materials, including course notes and all the class examples.

Class Prerequisites

Experience in the following areas is required:

• Students should be well-versed in JSP page authoring. Knowledge of JSP 2.0 is a plus, but is not required; the module's primary audience is JSP 1.x authors.

Technical Requirements

Our computer technical requirements and setup process is easy, with support just a click away.

• Onsite and Instructor-led Online course technical requirements and setup instructions.
• WebEx system requirements for Instructor-led Online delivery option.
