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.
i-net KONNEKTER is a new type of JDBC driver. It allows you to develop an applet or server application that supports different DBMS. It enables remote access to JDBC drivers. You can use it with MS SQL Server, Oracle, DB2, Sybase, MySQL, PostgreSQL, Informix, ODBC, MS Access, and many other databases.
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.
db4o is an object database for Java and all .NET environments. Its features include ACID transactions, automatic class schema recognition, query-by-example, a S.O.D.A. object querying API, native queries, LINQ support on .NET, callback methods, memory files, cascade-on-delete, multi-threaded access, and Java Webstart and servlet support.
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.
BlueJ is an interactive Java development environment. It provides a unique user interface that presents a graphical display of the application classes and their relationships, and it lets users interactively create objects of any class. Once objects have been created, users can interact with them directly. This interaction mechanism allows for much greater testing and experimentation than in conventional environments. BlueJ is suited for teaching and learning OO and Java.
Piccolo2D is a toolkit that supports the development of 2D structured graphics programs, in general, and Zoomable User Interfaces (ZUIs), in particular. A ZUI is a new kind of interface that presents a huge canvas of information on a traditional computer display by letting the user smoothly zoom in to get more detailed information and zoom out for an overview. It uses a "scene-graph" model that is common to 3D environments. This means that Piccolo maintains a hierarchical structure of objects and cameras.
SDE for NetBeans is a UML modeling environment tightly integrated with NetBeans. It lets you draw all types of UML diagrams (use case diagram, class diagram, sequence diagram, activity diagram, etc.) in NetBeans, reverse source code (Java, C++, XML, XML Schema, CORBA IDL, etc.) to UML models, and generate Java source from UML diagrams. It features a Rational Rose importer, an XMI importer, HTML/PDF documentation generators, and plug-in and template support.
