Apache Commons
The Commons Proper
- Um repositório de componentes Java reusáveis.
Originado no projeto Jakarta, Apache Commons é um grande complemento à API
Java SE, essencial para tarefas comuns não cobertas pela API padrão de Java.
Antes de implementar qualquer recurso básico de programação que você não
encontrou na API Java, não deixe de conferir se ele já existe no
Apache Commons, evite “reinventar a roda”.

Apache Commons Logging
Anteriormente Jakarta Commons Logging (JCL).
Commons Logging provê uma interface Log e uma LogFactory que visam ser tanto
uma implementação leve quando uma abastração independente de outros toolkits
de logging, como JDK logging API (JSR-47) e Log4J.
Padrão de facto para API logging.

JSR 310: Date and Time API
Esta JSR em andamento proverá uma API nova e melhorada para data e tempo em Java.
Submetida por Stephen Colebourne, criador da biblioteca Joda-Time.
The main goal of JST-310 is to build upon the lessons learned from the first
two APIs in Java SE (Date and Calendar) and on experience gained from the
Joda-Time project, to provide a more advanced and comprehensive model for
date and time manipulation.
The new API will be targeted at all applications needing a data model for
dates and times. This model will go beyond classes to replace Date and Calendar,
to include representations of date without time, time without date, periods,
durations, and intervals.
Announcing JSR 310 - Date and Time API, Stephen Colebourne's Weblog, 30/jan/2007.

Joda Time
Por Stephen Colebourne. Joda-Time é um projeto código-aberto para prover uma
API de qualidade para datas e tempo. Interfaces e implementações incluem:
DateTime (substituto imutável para JDK Calendar) e DateMidnight;
LocalDate, LocalTime e LocalDateTime (sem time zone);
Chronology e DateTimeZone (ISO
8601 e outras cronologias, calendários e fusos horários);
Interval, Period e Duration (intervalos e períodos de tempo);
mais formatação e varredura (parsing).

ANTLR, ANother Tool for Language Recognition, is a language tool that provides
a framework for constructing recognizers, interpreters, compilers, and
translators from grammatical descriptions containing actions in a variety of
target languages. ANTLR provides excellent support for tree construction,
tree walking, translation, error recovery, and error reporting.

JFlex - The Fast Scanner Generator for Java
JFlex is a lexical analyzer generator (also known as scanner generator) for Java,
written in Java. It is also a rewrite of the very useful tool JLex developed
by Elliot Berk at Princeton University.
JFlex is designed to work together with the LALR parser generator CUP by
Scott Hudson, and the Java modification of Berkeley Yacc BYacc/J by Bob Jamison.
It can also be used together with other parser generators like ANTLR
or as a standalone tool.
