Annotated List of Open Source Projects

KDG Commons
Yet another library of utility classes, in the mold of Apache Commons. Created because I found myself rewriting the same classes over and over, and the adoption delay for submissions to Apache Commons is quite long (although one of my classes did end up there).
Practical XML
Utility classes to enhance Java's default XML library. In addition to simple utility methods like “add a child and inherit parent's namespace,” provides a nice XPath wrapper and a library to convert between XML and a variety of other formats.
Appenders for Log4J and Logback that support writing to multiple AWS destinations. An alternative to Logstash or the Amazon logging agents, particularly when feeding the logs into ElasticSearch.
An assortment of AWS-specific examples and tools. Mostly written in Python. Many are used as examples for blog posts.
Extensions to Apache Commons BCEL. At the present time, this is focused on supporting annotations.
A set of tools for examining and cleaning Maven POM files. See also the series of blog posts that I wrote in July and August of 2012 about was to simplify Maven projects.
A tool for examining Java Web Applications to discover their URLs. Supports Spring 2, Spring 3 (annotation-driven), and basic servlets and JSPs.
This project has been archived.
