Integrated Testing Builds In Quality

Achieve more reliable applications through methodologies, modeling, and new techniques for finding and analyzing errors. Application development tools have spent the last several years maturing and building up compliance with successive versions of Java Development Kits (JDKs);); Java standard and enterprise edition toolkits; and supporting technologies such as JavaServer Pages (JSPs), Enterprise JavaBeans (EJBs), Java API for XML (JAX), JDBC, and a host of others. Today you can use virtually any Integrated Development Environment (IDE) to build a distributed application, using virtually any of the established technologies under the umbrella of Java 2 Platform, Enterprise Edition (J2EE) or Java 2 Platform, Standard Edition (J2SE).

Streamline Your Exception Processing

Make applications easier to maintain and support by implementing exception handling at an application level.The primary reason exceptions exist is to produce and report information about an error and the circumstances in which it occurred. (Consider my liberal use of the word “exception” to be a generic term for any type of object that extends java.lang.Throwable.)

Turn a JTable into a Spreadsheet

The spreadsheet is part of our everyday lives. Most of us have used one to help us calculate and present data quickly and efficiently. The JTable component, which is available in the Swing package, has itself become popular among Java developers, and you might have already imagined using a JTable as a spreadsheet for your application.

Develop Faster With Tag Libraries

For easier and faster development, Struts provides five tag libraries that act and function just like other JSP tag libraries: HTML, Bean, Logic, Template, and Nested. This three-part article series covers the HTML tag library. Part 1 discusses how to configure a Struts application to use this library and its first group of tags, Part 2 explains the second group of tags, and Part 3 demonstrates an application that uses this library.
