Summary

Instead of stumbling around the Jakarta site and reading pages of documentation written by groups of disconnected developer teams, The Jakarta Commons Cookbook helps developers by aggregating information into a survey of the available tools in a way that allows them to get up and running quickly. The Jakarta Commons Cookbook introduces design possibilities, explores combining utilities in novel assemblies to create complex applications, and provides example code for a wide variety of uses.
