CloverETL is Java-based tool/framework for data integration and creation of data transformations. It is component based and follows the concept of transformation graphs which consist of individual nodes/components performing simple (or complex) operations on data. Any transformation can be defined as a set of interconnected nodes through which data flows. CloverETL can be used as a standalone application or be embedded into a larger project.
JFreeChart is a chart library for the Java platform that supports a wide range of charts including pie charts (2D and 3D), bar charts (horizontal and vertical, regular or stacked, with optional 3D-effects), line charts, XY plots, scatter plots, time series charts, high/low/open/close charts, candlestick plots, Gantt charts, Pareto charts, combination charts, and more. It is suitable for use in applications, applets, servlets, and JSP.
tinyMAS is a multiagent platform that provides base concepts (such as kernel, message, yellow pages, white pages, and transport service) and extended concepts (such as environment, influence, and perception). It aims to provide an easy-to-understand and and easy-to-use platform dedicated for multiagent engineer/research courses. TinyMAS is no longer under development. A large amount of its source code has been merged into the Janus platform.
RMIIO is a library that makes it as simple as possible to stream large amounts of data using the RMI framework (or any RPC framework). The RMI framework makes it very easy to implement remote communication between Java programs, yet does not provide any ready solutions for sending large files without blowing out memory on the client or server. What you really want to do is stream data from the client to the server using a framework that does not really expose streaming. The RMIIO library provides some very powerful classes that enable a client to stream data to the server using only a few extra lines of code.
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.
FM-Classic provides an easy way to get data from Java servlets into Web pages. It also helps you keep graphic design separate from application logic. The template language is powerful and intuitive, the compiler is fast, and the output approaches the speed of static HTML pages. FM-Classic is a continuation of the FreeMarker 1.x code base.
Jupidator is a framework to automate the updating procedure of an application. It can be used on all major platforms. It makes it easy to integrate the self-update feature to any program in any language. It has various levels of file description granularity, and the developer can work with file groups or even single files, while keeping track of the change-log in a user friendly manner. It is based on XML for describing files and Swing or a console to display visuals.
JavaPlot is a library that can be used as a way to create gnuplot plots on the fly through pure Java commands. In contrast with other common gnuplot Java libraries, it uses Java structures to store the various plot parameters, including datasets. Moreover, it is flexible enough to give special parameters to gnuplot, even if the library does not yet support it. It uses Java's Exceptions to inform the user if something went wrong.
