Java Network Stack provides a Java library for research oriented network programming.

Java Network Stack is a library used by the DIMES project to create new internet measurements. It provides a clean API for packet manipulation, send, receive, filter, and analysis. It is a unification of raw socket capabilities, MAC level networkingm, and IPv6 capabilities.

C++ Elliptic Curve Cryptography library is a C++ library for elliptic curves cryptography.
Libecc is a C++ elliptic curve cryptography library that supports fixed-size keys for maximum speed.
The goal of this project is to become the first free Open Source library providing the means to generate safe elliptic curves, and to provide an important source of information for anyone with general interest in ECC.
Enhancements:
- This version brings the code completely up to date again with the latest of version of the working set (autoconf, compiler, etc.).
- The previous version was almost two years old and didnt even compile anymore.

Java Tools is a lightweight integrated development environment for creating, compiling, and executing Java applications and applets.
Java Tools includes point and click access to the Java files, commands, and documents. It also includes a built-in text editor and user interface for the Java debugger.
It is intended for the new Java user who needs help getting started. Its also for the more experienced Java user who wants easy access to the Java commands and a text editor.
Main features:
- GUI with built-in help and small footprint.
- Point and click access to all files (Java, manifest, HTML, image and sound) and directories (package).
- Point and click access to all commands for compiling (javac), archiving (jar), documenting (javadoc), executing (java), debugging (jdb) and disassembling (javap).
- Point and click access to all documents (Java API Specification, Java Tools and Utilities, Java Features and Java Tutorial).
- Point and click creation of all files (Java, manifest and HTML) and directories (package).
- Point and click installation of distribution archive files (Java document, Java source code, Java Tutorial and Sun Tools).
- Automatic determination of class file dependencies for archiving (jar) and documenting (javadoc) Java files.
- Checking for unused, redundant and missing imports.
- Logging of all commands invoked by GUI.
- Code metrics for Java files.
- Built-in text editor (see Edit for details).
- Built-in user interface for the Java debugger with command-line editing and history.
- Self-installing executable (Java archive file).
- Comprehensive installation and user documentation for Java and Java Tools.

Java::JCR::Workspace is a Perl wrapper for javax.jcr.Workspace.
This is an automatically generated package wrapping javax.jcr.Workspace with a nice Perlish API.
For full documentation of what this class does, see the Java API documentation: http://www.day.com/maven/jsr170/javadocs/jcr-1.0/javax/jcr/Workspace.html
The deviations from the API documentation include the following:
- You will need to use Perl, intead of Java, to make any use of this API. (Duh.)
The package to use is Java::JCR::Workspace, rather than javax.jcr.Workspace.
- All method names have been changed from Java-style camelCase() to Perl-style lower_case().
Thus, if the function were named getName() in the Java API, it will be named get_name() in this API. As another example, nextEventListener() in the Java API will be next_event_listener() in this API.
- Handle exceptions just like typical Perl. Java::JCR::Exception takes care of making sure that works as expected.

CryptoServer is OpenSource Server-side cryptography tool and run as daemon.

It is already tested in very busy environment and can support over one million transaction an hour.

CryptoServer accept the GPL License and can use it for any purpose as is.

Java RSS Ticker is a Java RSS and Atom Ticker/Aggregator/Reader. I had checked out a number of tickers that look pretty as they scroll etc., but took a lot of CPU cycles and cost money. I wanted a simple, OS independent, ticker so I wrote this one in Java.

C# Java Virtual Machine is a tiny implementation of the Java VM, including simple native classes. This project is written using the C# language. The VM is very easily expandable by writing additional native or Java classes.
Enhancements:
- The DbConnection class, which provides a connection to MS SQL or PostgreSQL using ADO.NET, was added.
- The Syst.MachineName method, which returns the machine name, was added.
- String.startsWith and String.endsWith functions were added.
- Some comments for VM.cs were written.
