Zinnia is a simple, customizable and portable online hand recognition system
based on Support Vector Machines. Zinnia simply receives user pen strokes as a
sequence of coordinate data and outputs n-best characters sorted by SVM
confidence. To keep portability, Zinnia doesn't have any rendering
functionality. In addition to recognition, Zinnia provides training module that
allows us to create any hand-written recognition systems with low-cost.

JamVM is an extremely small Java Virtual Machine which conforms to the
JVM specification version 2 (blue book).
It is designed to support the full specification, and includes support
for object finalisation, Soft/Weak/Phantom References, class-unloading,
the Java Native Interface (JNI) and the Reflection API.
Jasmin is a Java Assembler Interface. It takes ASCII descriptions for Java
classes, written in a simple assembler-like syntax and using the Java Virtual
Machine instruction set. It converts them into binary Java class files
suitable for loading into a JVM implementation.
Checkstyle is a development tool to help programmers write Java code
that adheres to a coding standard. It automates the process of
checking Java code to spare humans of this boring (but important)
task. This makes it ideal for projects that want to enforce a coding
standard.
Checkstyle can be used as either a commandline utility or as an
Ant task.
Avis is a multicast event bus server. Providing the ability to publish and
subscribe to events. The protocol is compatible with the commercial Elvin
implmentation developed by Mantara Software.
OpenJDK is an open-source implementation of the Java Platform, Standard Edition.
Much of the OpenJDK code is licensed under the GPL version 2 with the
Classpath exception. The Java Hotspot virtual machine source code is
licensed under the GPL version 2 only.
The JavaHelp system is an online help system that developers can use to
add online help to their Java platform applications. The JavaHelp system
is both a JCP specification (JSR 97) and a reference implementation of
that specification. The JavaHelp system open source project includes the
source to the reference implementation.
The Java Chart Constuction Kit (JCCKit) is a small (< 100Kb) Java library and a
very flexible framework for creating scientific charts and plots.
The main purpose is to provide a flexible kit for writing Java applets and
application with the need for visualizing scientific data. If you are looking
for a lean scientific chart and plot library without all the unwanted bells and
whistles of the heavy competitors try JCCKit.
The key features of JCCKit are:
* small (< 100Kb jar file)
* highly configurable due to a sophisticated configuration concept
* extensible (1/3 of all classes are interfaces or abstract classes.)
* automatic updating if data changes
* easy programming of dynamic charts and plots
* automatic rescaling if canvas size changes
* out-of-the-box applet for presenting static data on a web page without
Java programming
* automatically generates a legend
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!
