This package specifies a means for obtaining objects in such a way as to maximize reusability, testability and maintainability compared to traditional approaches such as constructors, factories, and service locators (e.g., JNDI). This process, known as dependency injection, is beneficial to most nontrivial applications.

Many types depend on other types. For example, a Stopwatch might depend on a TimeSource. The types on which a type depends are known as its dependencies. The process of finding an instance of a dependency to use at run time is known as resolving the dependency. If no such instance can be found, the dependency is said to be unsatisfied, and the application is broken.

Argparse4j is a command line argument parser library for Java based on Python's argparse module.

Commons-dbcp allows you to share a pool of database connections between users. Creating a new connection for each user can be time consuming and even unfeasible when the number of simultaneous users is very large. This package provides a way to share a poole of connections to reduce that load.

XMLUnit provides you with the tools to verify the XML you emit is the one you want to create. It provides helpers to validate against an XML Schema, assert the values of XPath queries or compare XML documents against expected outcomes.

ANTLR, ANother Tool for Language Recognition, (formerly PCCTS) is a language tool that provides a framework for constructing recognizers, compilers, and translators from grammatical descriptions containing Java, C#, C++, or Python actions. ANTLR provides excellent support for tree construction, tree walking, and translation.

This package provides the Eclipse Java core batch compiler.

JOpt Simple is a Java library for parsing command line options, such as those you might pass to an invocation of javac. In the interest of striving for simplicity, as closely as possible JOpt Simple attempts to honor the command line option syntaxes of POSIX getopt and GNU getopt_long. It also aims to make option parser configuration and retrieval of options and their arguments simple and expressive, without being overly clever.

This library supplies some utility classes needed for libraries from the SIS division at ETH Zurich like jHDF5.

Jar Jar Links is a utility that makes it easy to repackage Java libraries and embed them into your own distribution. Jar Jar Links includes an Ant task that extends the built-in jar task.

This package provides the Java development kit OpenJDK.

Java-jboss-transaction-api-spec implements the Transactions API. A transaction is a unit of work containing one or more operations involving one or more shared resources having ACID (Atomicity, Consistency, Isolation and Durability) properties.

This package contains core low-level incremental (streaming) parser and generator abstractions used by the Jackson Data Processor. It also includes the default implementation of handler types (parser, generator) that handle JSON format.

The Commons Lang components contains a set of Java classes that provide helper methods for standard Java classes, especially those found in the java.lang package in the Sun JDK. The following classes are included:

• StringUtils - Helper for java.lang.String.

• CharSetUtils - Methods for dealing with CharSets, which are sets of characters such as [a-z] and [abcdez].

• RandomStringUtils - Helper for creating randomised strings.

• NumberUtils - Helper for java.lang.Number and its subclasses.

• NumberRange - A range of numbers with an upper and lower bound.

• ObjectUtils - Helper for java.lang.Object.

• SerializationUtils - Helper for serializing objects.

• SystemUtils - Utility class defining the Java system properties.

• NestedException package - A sub-package for the creation of nested exceptions.

• Enum package - A sub-package for the creation of enumerated types.

• Builder package - A sub-package for the creation of equals, hashCode, compareTo and toString methods.

The JavaMail API provides a platform-independent and protocol-independent framework to build mail and messaging applications.

ASM is an all purpose Java bytecode manipulation and analysis framework. It can be used to modify existing classes or dynamically generate classes, directly in binary form. The provided common transformations and analysis algorithms allow easily assembling custom complex transformations and code analysis tools.

jsch-agent-proxy is a proxy program to OpenSSH's ssh-agent and Pageant included in Putty. This component contains an implementation of USocketFactory using JNA (Java Native Access).
