The driver is completely platform-independent and does not require installing additional client or server software to provide access to MDB files. It can be effectively used to create, process, and export Microsoft Access databases in your Java applications. It supports most keywords of ANSI SQL'92, supports inner and outer table joins, supports CREATE, INSERT, UPDATE, and DELETE statements, supports transactions, and supports aggregate, numeric, string, conversion, and user-defined SQL functions.
Koalog Constraint Solver is a powerful constraint solver written in Java. It provides cutting-edge technology for solving satisfaction and optimization problems, including scheduling, time-tabling, resource-allocation, puzzles (sudoku.koalog.com is powered by Koalog Constraint Solver), and configuration (Koalog Configurator is powered by Koalog Constraint Solver).
JGui is a collection of useful Java GUI components and utilities. JGui includes a docking windows framework for Swing and AWT; a dynamic tree framework; ThreadManager, which helps to distribute tasks to a number of threads; TLToolTipManager, which shows hidden parts of JTree's and JLabel's cells; JShape, a non-rectangular translucent Swing component; and many more.
HBCI4Java is a Java library for the HBCI home banking interface. It supports almost all aspect of the HBCI versions 2.01, 2.1, 2.2, HBCI+ and FinTS-3.0 (with PIN/TAN support). Its API is very application-oriented, so no knowledge about HBCI is required. The HBCI client package can be used to develop applications using HBCI features. The HBCI server package can be used to develop your own HBCI servers. This may be useful for credit institutes or software developers who want to setup their own HBCI test server.
FDT is an application for efficient data transfers that is capable of reading and writing at disk speed over wide area networks (with standard TCP). It can be used to stream a large set of files across the network, so a large dataset composed of thousands of files can be sent or received at full speed, without the network transfer restarting between files. It is written in Java, runs an all major platforms, and is easy to use.
OpenSubsystems is set of business components for Java applications such as security, search, inventory management, order processing, shopping, email and fax communication, document management, imaging, and others. The components can be used directly on top of Java Virtual Machine (POJO) or using various J2EE application servers (EJB). This is all without changing a single line of code.
JPerf is a perfect hash function generator for Java. The principle of perfect hashing is to reduce the average constant overhead of a hash table by precomputing a hash function which is optimal for the key set. Other advantages include a reduction in memory usage. Finding such a hash function is hard, especially in the general case. These run-time savings come at a cost of increased map creation time. JPerf can create a perfect hash function for a given set of keys and values.
InfoNode Docking Windows is a powerful and easy-to-use docking windows framework for Java Swing applications. InfoNode Docking Windows includes a flexible tabbed panel library which is also available separately as InfoNode Tabbed Panel. Both libraries are available under either the GPL or a commercial license. A docking windows framework is commonly seen in, but not limited to, modern integrated software development environments. It is responsible for managing windows inside an application and lets the user customize the layout to his or her own preference.
GridSphere Plug-in for GRIA is a GridSphere (http://www.gridsphere.org/) plug-in for the GRIA 5.1 middleware (http://www.gria.org/). The plug-in is suitable to be used not only with GridSphere, but also with any other Java application which can use a GRIA 5.1 plug-in. This way, a GridSphere user can, for example, submit new jobs in a GRIA 5.1 Server through a user-friendly portal as well as monitor submitted jobs, having a keystore signed by the GRIA server administrator.
