Perfmon4j is a suite of performance monitoring tools that are intended to be used to diagnose performance bottlenecks and monitor throughput and response time in production Java applications. Its main features include servlet response time monitoring, detailed thread trace sampling, Java instrumentation that enables Package, Class, and Method monitoring without code modification, snapshot monitoring of system metrics including Garbage Collection, Memory Pools, etc., an API for applying additional monitoring points via method annotations or in-line timers, and support for dynamically enabling monitors in running applications.
Flat File Reporting allows you to use fixed width files as a data source in IReport designer and Jasper Reports. It uses a record description (which can be XML, Cobol, or RecordEditor Record Layouts) to describe the file format. You can design reports via IReports wizards or by draging and dropping fields onto the report. It can also be used for reports for the RecordEditor and JRecord Projects.
jurlmap is a Java library for enabling your Web apps to have clean, REST-like URLs. Some of its features are a simple pattern language for brevity and convenience, direct binding of parameters to bean properties or method parameters, and configuration in plain Java and annotations.
JEFF is an explanation facility framework written in Java. Explanation facilities date from the era of expert systems (ES), where they were used in order to provide an explanation about the inference process. The explanation they provided was supposed to clarify how the ES reached its conclusions or why it asked some question during fact acquisition. Nowadays, traditional ES development environments ("shells") have been replaced by rule engines (RE) and business rule management systems (BRMS), which seem to lack explanation facility functionality. JEFF was created in order to remedy this.
ServoMaster provides hardware independent abstractions to servos and servo controllers. It has implementations for several servo controller families, including Phidget, Pololu, Parallax, and SSC. It has support for servo and controller metadata, introspection, and capabilities discovery.
The Whole Brain Catalog is a 3D virtual environment to facilitate solutions for currently intractable challenges in brain research. It is meant to enable the synthesis of data measured from brains at different scales into more coherent models of brain structure and function. The Whole Brain Catalog is a client-server platform that provides rich 3D views for researchers to zoom in, out, and around structures deep in a multi-scale spatial framework of the mouse brain. A 3D graphics engine used in graphics-intensive computer gaming generates high-resolution visualizations that bring data to life through biological simulations and animations.
