As a Java developer, you're always looking for tools to help in your web and application development. Maybe you've heard of the Jakarta Commons open source Java tools. The Jakarta Commons is an open source Jakarta subproject where developers create and maintain a collection of twenty-plus independent Java components and utilities that serve useful purposes. Jakarta Commons packages include utilities for web, XML, networking, building and testing applications, and some that help other packages work better together. Jakarta Commons packages are designed to be reusable. Each one is a time saver by itself, and when used in combination the results can be very powerful.
But in searching for information on the Jakarta Commons tools, you find it hard to locate documentation relevant to your needs. You don't have lots of time to spend searching for information on a specific Jakarta Commons tool to determine what it does and how to incorporate it in your code. If you are looking for a single source for clear information and samples on how to use the Jakarta Commons tools, then the Jakarta Commons Cookbook is for you.
The Jakarta Commons Cookbook summarizes each of the available Jakarta Commons packages and contains practical and efficient recipes for making the most out of the Jakarta Commons open source Java tools. You don't have to be an expert, since the book explains how and why to use a utility, pitfalls to avoid, and where to look for additional information on Jakarta Commons utilities. It introduces design possibilities and explores combining Jakarta Commons utilities in novel assemblies to create complex applications. The book offers detailed code samples and insider tips—making it a valuable resource whether you are an expert Java developer or a novice. If you want to quickly learn how to use Jakarta Commons timing-saving utilities or have an invaluable resource for Jakarta Commons questions and techniques, then the Jakarta Commons Cookbook is for you.

One of the beauties about Java, compared to earlier languages like C or Pascal, is the huge set of library classes that comes with the default distribution. An immense amount of code, all for free. Any experienced Java programmer knows this. But what if you could also get another set of free classes that extends the functionality even more? And has been well tested? O'Brien educates us about this - the Jakarta Commons. A nifty amount of heavy code. It can be highly worth your while to peruse this for useful classes. Here is a brief excerpt of what is offered. Consider the default maths classes that come with Java. Important. But still very primitive compared to the decades of effort put into various mathematical libraries in other languages like Fortran. Of course, many of those tend to be proprietary. Now, in Commons, we have Maths classes. These can solve a linear system of equations. In other words, matrix arithmetic is implemented. Opens up entire regions of electrical circuit modelling and control systems theory, for example. For statistics, simple regressions between two variables is now computed. And complex numbers can be explicitly handled with the ComplexMath class. It can be appreciated that the new Commons maths classes fill longstanding gaps in the default maths ability of Java, which has been weak in numerical methods and high performance computing. It greatly strengthens the credibility of developing applications in those fields with Java.Was this review helpful? Yes NoThank you for your feedback.
