OpenMap is a JavaBeans-based GIS toolkit for building applications and applets needing geographic information. Using OpenMap components, you can access data from legacy applications, in-place, in a distributed setting. At its core, OpenMap is a set of Swing components that understand geographic coordinates. These components help you show map data, and help you handle user input events to manipulate that data.
OSCache is a high performance J2EE caching solution that can cache portions of JSP pages, entire HTTP responses (including dynamically generated images), and arbitrary Java objects. It can provide your J2EE application with huge performance gains and graceful error tolerance (e.g., in the event of a DB failure, cached content is served).
ozone is a transaction-based, object-oriented database management system completely implemented in Java and distributed under an open-source license. It aims to evolve a technology that allows developers to build pure object-oriented, Java database applications. ozone also contains a full-featured XML API that allows you to use it as an XML repository.
PAT is an interpreter for a scheme-like functional language, also named PAT. It is written completely in Java and can run on any Java supported platform. Since the language is Turing-complete, it can be used for any type of computer application. It was originally developed to do performance analysis using list manipulation. However, it has grown into much more than that and can be used for many things, including: interactive testing of code written in Java, reading/writing Java objects from/to XML files, launching applications remotely. Some of the features of PAT are built-in lists and common list procedures such as filter, sort, map, append, and foreach; math primitives for arithmetic, statistics, trigonometry, and random numbers; built-in objects for dates and times; reflection primitives for introspection of Java objects; a table library; and simplified syntax for interactive Java object manipulation. It runs on Linux, All Java Platforms, Windows NT, Windows 2000
PilotBean is a package that provides a Java interface to the 3Com PalmPilot (TM) device via Pilot Desktop application. PilotBean's classes allow user Java applications to work with Pilot Desktop's data files, i.e. Memopad and Datebook. Datebook's and Memopad's entries can be added, edited and listed. Datebook and Memopad can also be "listened to" to detect new or updated entries.
PngEncoder is a Java class which takes a Java Image object (based on DirectColorModel) and returns a byte-array in PNG format. This byte-array is suitable for saving as a PNG file or delivery to a client from a servlet. The class optionally encodes alpha information from the Image. PngEncoderB takes a Java BufferedImage object (which may have either a DirectColorModel or IndexColorModel) and returns a byte array in PNG format..
Pnuts is a scripting language totally written in Java. Users can use Pnuts to access the Java environment interactively. This helps developers to test their programs efficiently and easily. An interesting usage for this language is to be used as "glue" for JavaBeans or beween any Java API. Also, it can be embedded in a Java program to make processing more flexible.
Reliable Multicast SDK (aka Remade) is a set of Java-based APIs intended for the creation of reliable multicast delivery applications. A reliable multicast transport protocol is implemented and serves as the basis for Remade. The toolkit provides a high-level intuitive interface to the protocol. One can simply call "transmit file" function at the head-end server, "receive file" function at the end-user client, and not to worry about multicast address allocation, reliability repair mechanism, or other details.
