Jaiwls is a component oriented framework with bundled a servlet Web server (Jetty) and HTML widget library. It is easy to integrate in existing applications with static compiled Java classes and supports dynamic websites using Groovy, a runtime injectable singelton instance, well formatted stack traces, a low memory footprint for compiled projects, powerful URL rewrites possible, a production mode (with no recompilation) for Groovy-based applications, and much more.
Jasymca is an interactive system for solving math problems. It supports arbitrary precision numbers and symbolic variables. Scalars, vectors, and matrices can be built from all datatypes and used in calculations. From the pseudoinverse of symbolic matrices over trigonometric simplifications to symbolic solutions of integrals and systems of equations, the main functionalities of CAS-programs are provided. Additionaly, high performance numerical routines from LAPACK and a plotmodule are implemented. The user interface can be selected from either an Octave/Matlab/SciLab-like language or a GNU-Maxima style. Three versions of Jasymca are provided to cover almost any computer platform: a midlet version for portable devices like cell phones or PDAs; a Java application for desktop PCs, laptops, and workstations; and an applet which can be integrated in Web pages.
MSBLayout is a layout manager for Java AWT and Swing that combines the nested-boxes approach of BoxLayout with flexible constraints as used by GridBagLayout. A concise API with good defaults minimizes the code required to get the layout you want. MSBLayout makes it easy to align and justify components and to synchronize their sizes. Gaps between components can be inserted automatically. Optimized resizing behaviour keeps your dialogs looking good when displayed larger or smaller than their preferred sizes. The API is also well suited for constructing layouts dynamically at run-time.
SpiderDB is a lightweight database schema crawler library developed using Java. It is a simple library that can be used to Crawler the underlying schema of a database and return POJO objects, which makes it very easy to use. This library takes care of all the differences among the various database management systems, and makes application code free from the DBMS differences.You keep using same POJOs even if you change the underlying DBMS.
