The Netty is an effort to provide an asynchronous
event-driven network application framework and tools
for rapid development of maintainable high performance &
high scalability protocol servers & clients.
The standard Java libraries fail to provide enough methods for
manipulation of its core classes. The Lang Component provides
these extra methods.
The Lang Component provides a host of helper utilities for the
java.lang API, notably String manipulation methods, basic
numerical methods, object reflection, creation and serialization,
and System properties. Additionally it contains an inheritable
enum type, an exception structure that supports multiple types of
nested-Exceptions and a series of utlities dedicated to help with
building methods, such as hashCode, toString and equals.
JGraph is the most powerful, lightweight, feature-rich, and thoroughly
documented open-source graph component available for Java. It is accompanied
by JGraphpad, the first free diagram editor for Java that offers XML, Drag and
Drop and much more!
With the JGraph zoomable component, you can display objects and relations
(networks) in any Swing UI. JGraph can also be used on the server-side, for
example to read a GXL graph, apply a custom layout algorithm, and return the
result as a HTML image map.
The Sigar API provides a portable interface for gathering system information
such as:
* System memory, swap, cpu, load average, uptime, loginsi
* Per-process memory, cpu, credential info, state, arguments, environment,
open files
* File system detection and metrics
* Network interface detection, configuration info and metrics
* TCP and UDP connection tables
* Network route table
This information is available in most operating systems, but each OS has their
own way(s) providing it. SIGAR provides developers with one API to access this
information regardless of the underlying platform. The core API is implemented
in pure C with bindings currently implemented for Java, Perl, Ruby, Python,
Erlang, PHP and C#. This port provides the Java bindings.
This is a port of JUnit, a simple testing framework for Java developed
by Erich Gamma and Kent Beck. Using JUnit you can build a test suite
that will help you measure your progress, spot unintended side
effects, and focus your development efforts.
JTiger is a unit test framework and tools for the Java 2 Platform. The
framework provides a useful abstraction on which to write unit test
fixtures and unit test cases. JTiger tools provide functionality
that is often desired in software unit testing environments. JTiger
development encourages Test Driven Development, though it doesn't
mandate it, and any unit testing software development technique
is sufficient.
MX4J is a project to build an Open Source implementation of the
Java(TM) Management Extensions (JMX) and of the JMX Remote API
(JSR 160) specifications, and to build tools relating to JMX.
JMX is an optional package for J2SE that provides a standard
way to manage applications. It can also be used to wrap legacy
systems and provide a standard interface to the outside world,
enabling the development of web services. JMX allows developers
to write more modular and loosely coupled system components and
reduce the complexity of large, interoperating systems.
JGraphT is a free Java graph library that provides mathematical graph-theory
objects and algorithms. JGraphT supports various types of graphs including:
* directed and undirected graphs.
* graphs with weighted / unweighted / labeled or any user-defined edges.
* various edge multiplicity options, including: simple-graphs, multigraphs,
pseudographs.
* unmodifiable graphs - allow modules to provide "read-only" access to
internal graphs.
* listenable graphs - allow external listeners to track modification events.
* subgraphs graphs that are auto-updating subgraph views on other graphs.
* all compositions of above graphs.
Although powerful, JGraphT is designed to be simple. For example, graph vertices
can be of any objects. You can create graphs based on: Strings, URLs, XML
documents, etc; you can even create graphs of graphs!
This is jikes, a java source to byte-code compiler. The compiler has been
made available by IBM under their open-source license, please see:
for details. To operate, the CLASSPATH environment variable must typically
be set to a colon-delimited list of source directories, class directories,
or zip files. Note that jikes will complain if a non-existant directory or
file is specified in CLASSPATH.
