Sequoia provides high availability and performance scalability for databases. It is is the continuation of the C-JDBC project. It provides transparent database clustering (partitioning, replication, etc.). It works with any Java application without code modification and with any database engine. It has been successfully tested with Tomcat, JBoss, JOnAS, WebSphere, MySQL, PostgreSQL, Apache Derby, HSQLDB, SAP DB, Oracle, DB2, Sybase, MS SQL Server, Firebird, and more.
The Java Application Monitor (JAMon) is a free, simple, high performance, thread safe, Java API that allows developers to easily monitor production applications. JAMon can be used to determine application performance bottlenecks, user/application interactions, and application scalability. JAMon gathers summary statistics such as hits, execution times (total, average, minimum, maximum, standard deviation), and simultaneous application requests. JAMon statistics are displayed in the sortable JAMon report.
Velocity is a Java-based template engine. It permits anyone to use the simple yet powerful template language to reference objects defined in Java code. When Velocity is used for Web development, Web designers can work in parallel with Java programmers to develop Web sites according to the Model-View-Controller (MVC) model, meaning that Web page designers can focus solely on creating a site that looks good, and programmers can focus solely on writing top-notch code. Velocity separates Java code from the Web pages, making the web site more maintainable over the long run and providing a viable alternative to Java Server Pages (JSPs) or PHP. Velocity also provides template services for the Turbine Web application framework, making a template service that allows Web applications to be developed according to a true MVC model.
Barcode4J is a barcode generation package. The following symbologies are currently implemented: Interleaved 2 of 5, Code 39, Codabar, Code 128, UPC-A and UPC-E (with supplementals), EAN-13 and EAN-8 (with supplementals), EAN-128, POSTNET, Royal Mail Customer Barcode, PDF417, and DataMatrix. Supported output formats are SVG, EPS (Encapsulated PostScript), Bitmap images (such as PNG or JPEG), and Java2D (AWT). Additional features include two APIs (XML-oriented and Bean-style), a Servlet with support for SVG, EPS, and bitmap output, a command-line interface, a demonstration applet, and extensions for Apache Xalan-J, SAXON, and Apache FOP.
Snippetory is a general Java template engine based on passive templates. In passive templates, template code and logic are clearly separated from each other. The templates contains very simple mark up. By removing logic, templates are directly accessible, fully parametrized, and free of context, and can easily be reused. Navigation, code competition, and structuring of the code with methods and classes are supported.
Uncle Unc is a framework for working with trees of objects. Existing services such as filesystems, code libraries, networks, log files, mailboxes and directories can be mapped onto this object tree, as can some traditional desktop applications. User interfaces work directly with the object tree, offering best of breed interface design (e.g. filtering, breadcrumb bars, paging, sorting, and file-explorer-like views) across the full range of services. The framework promotes clean design, completeness of representation, and reusability of both front end and back end code.
FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
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.
