A pure Java library which can read and write Ascii85 streams.
Ascii85 encodes binary data into ascii, using only 125% of the space of the original data - which is more efficient than most methods. PDF files use Ascii85 to encode their embedded images, etc.
The library provides an InputStream for reading and an OutputStream for writing. The mark() and reset() methods are supported, provided that the underlying stream supports them.
This project provides a delegate model authentication and authorization system which is driven from XML descriptions of the services' interfaces. On a method and argument level, you can detail your authorization mechanisms so that roles are what controls access, not users using java permissions.
Electric is an integrated-circuit design system that offers IC layout, schematic editing, and even textual hardware-description languages. It offers a wide range of synthesis and analysis tools for working on the circuitry. It has many importers and exporters for interfacing to other EDA (Electronic Design Automation) systems. It even has a constraint system for managing chip layout. For more information about Electric, see www.staticfreesoft.com
CodeModel is a Java library for code generators; it provides a way to generate Java programs in a way much nicer than PrintStream.println(). This project is a spin-off from the JAXB RI for its schema compiler to generate Java source files.
