Athena Framework for Java is a full fledged enterprise object-relational mapping (ORM) framework that employs metadata as mapping configuration. It greatly simplifies Java Web application development by removing the requirement of manual mapping and manual database schema updating. In addition to features like Java object persistence, powerful EJBQL querying execution, and comprehensive code generation, Athena has built-in support for multi-tenancy, which enables developers to build cloud applications easily. Athena can be easily integrated with other libraries like Struts or Spring to provide full stacks of service.
GRAL is a library for creating high quality plots and charts in Java. Many plot types are available like scatter plot, bubble plots, line plots, area plots, pie charts, and bar charts. Additionally, GRAL can exchange and process data (smoothing), and various plug-ins allow the import and export of data and graphics to formats like CSV, JPEG, PNG, EPS, PDF, or SVG.
Icwri is a lightweight, very simple, service-oriented Java built-in script. It can help Java developers build some application interfaces in a service-oriented style. It can also help non-technical people join the development team to write their own application scripts to enforce business rules and decisions. Icwri service providers and consumers can be either Icwri scripts or Java classes. An Icwri script can run all alone, but the primary purpose of Icwri script is to have an assistant language of Java. It can run on any system with JDK/JRE 1.5 or above installed. It does not support Java SE 6 Script Engine because of the service-oriented design and the requirement to support Java SE 1.5 users.
DJ Swing Suite provides some components and utilities that are often needed or greatly help the creation of rich Swing user interfaces. The components include, among other things, combo buttons, tri-state check boxes, links, extended label (selectable/multi-line) and text/number fields with support for validation, notification tips, formatters, and masks. The utilities bring features like auto-scroll with middle mouse click, automatic fitting of table columns, and conversion of wildcard expressions.
JTelIRC is an advanced IRC framework for Java. It is mainly intended for writing automated clients ("bots"), but may be used for normal clients as well. It provides an intuitive and well documented Java interface to IRC and makes it extremely easy to write advanced clients quickly.
JagPDF is a library for generating PDF documents in C/C++, Python, and Java. It supports TrueType (subsetting) and standard 14 Type 1 fonts, font metrics, Unicode, UTF-8 and common 8-bit character encodings, images (JPEG, PNG, or custom), paths, color spaces (RGB, CMYK, CIE based, ICC profiles, indexed), encryption, bookmarks, hyperlinks, and more.
P~ (pronounced "P tilde") is a Java-like scripting language and regular expression engine. P~ offers novel powers to match, extract, and transform documents. Regex novelties include an easy-to-read algebraic syntax and general capture and statement insertion side-effects. This is a great benefit to Java users, who no longer need to outsource difficult regex problems to Perl/Python scripts, since ptilde is offered as a Java library as well as a standalone scripting engine.
DJ Native Swing allows you to easily integrate some native components into Swing applications, and provides some native utilities to enhance Swing's APIs. The main focus is the integration of a native Web browser and Flash Player using a Swing-like API. All the threading issues and general integration headaches are handled automatically. It uses SWT under the hood, and thus should work everywhere SWT can be placed inside a Swing component.
