The ZK Mobile is a ZK extension that enables ZK applications to run on mobile devices with little programming. With the event-driven components and a markup language, programming is as simple as programming desktops and designing screens is as easy as authoring HTML pages. No JavaME prerequisite is required.
EZMorph is simple Java library for transforming an Object to another Object. It supports transformations for primitives, Objects, and multidimensional arrays, compatibility with JDK 1.3.1, and small memory footprint (~76K). It began life as the converter package in Json-lib but became a project on its own.
dao-zero is a tiny Java bean used to reduce the source of a persistence tier based on Spring's iBatis support. The usual way to use iBatis in Spring is to write code and invoke the iBatis API explicitly. dao-zero invokes the iBatis API for the developer automatically, without the need to write implementation code. It will implement DAO interfaces automatically and invoke iBatis SQL mapped statements for you. You can use it to replace your DAO bean class directly.
x4juli is a port of the main parts of log4j to the J2SE Logging API. The default implementation is incomplete and therefore still not widely used, even when introduced in J2SE 1.4. x4juli provides logmanagers, formatters, handlers, and filters to fill the gap. The interface and use of the original API has not been changed. Additionally, x4juli delivers a native implementation of the Jakarta Commons Logging (JCL) API and the Simple Logging Facade for Java (SLF4J) API.
