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.

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.

This package provides a library of matcher objects (also known as constraints or predicates) allowing match rules to be defined declaratively, to be used in other frameworks. Typical scenarios include testing frameworks, mocking libraries and UI validation rules.

This package provides annotations for security. It provides packages in the javax.annotation and javax.annotation.security namespaces.

This is the GNU servlet API distribution, part of the ClasspathX project. It provides implementations of version 3.0 of the servlet API and version 2.1 of the Java ServerPages API.

The Apache Commons Net library implements the client side of many basic Internet protocols. The purpose of the library is to provide fundamental protocol access, not higher-level abstractions.

The Xerces2 Java parser is the reference implementation of XNI, the Xerces Native Interface, and also a fully conforming XML Schema processor.

Xerces2-J supports the following standards and APIs:

• eXtensible Markup Language (XML) 1.0 Second Edition Recommendation

• Namespaces in XML Recommendation

• Document Object Model (DOM) Level 2 Core, Events, and Traversal and Range Recommendations

• Simple API for XML (SAX) 2.0.1 Core and Extension

• Java APIs for XML Processing (JAXP) 1.2.01

• XML Schema 1.0 Structures and Datatypes Recommendations

• Experimental implementation of the Document Object Model (DOM) Level 3 Core and Load/Save Working Drafts

• Provides a partial implementation of the XML Inclusions (XInclude) W3C Candidate Recommendation

Xerces is now able to parse documents written according to the XML 1.1 Candidate Recommendation, except that it does not yet provide an option to enable normalization checking as described in section 2.13 of this specification. It also handles namespaces according to the XML Namespaces 1.1 Candidate Recommendation, and will correctly serialize XML 1.1 documents if the DOM level 3 load/save API's are in use.

Commons-IO contains utility classes, stream implementations, file filters and endian classes.

EasyMock is a Java library that provides an easy way to use mock objects in unit testing.

This package provides the Java development kit OpenJDK built with the IcedTea build harness.

This package provides the Equinox application container for Eclipse.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the support annotations for metatype.

The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction for various logging frameworks (e.g. java.util.logging, logback, log4j) allowing the end user to plug in the desired logging framework at deployment time.

This package provides the Java development kit OpenJDK.

QDox is a high speed, small footprint parser for extracting class/interface/method definitions from source files complete with JavaDoc @tags. It is designed to be used by active code generators or documentation tools.

SLF4J binding for the Simple implementation, which outputs all events to System.err. Only messages of level INFO and higher are printed.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains bundle tracking utility classes.

Stax2 API is an extension to basic Stax 1.0 API that adds significant new functionalities, such as full-featured bi-direction validation interface and high-performance Typed Access API.

TestNG is a testing framework inspired from JUnit and NUnit but introducing some new functionalities that make it more powerful and easier to use.

The Bean Scripting Framework (BSF) is a set of Java classes which provides scripting language support within Java applications, and access to Java objects and methods from scripting languages. BSF allows one to write JSPs in languages other than Java while providing access to the Java class library. In addition, BSF permits any Java application to be implemented in part (or dynamically extended) by a language that is embedded within it. This is achieved by providing an API that permits calling scripting language engines from within Java, as well as an object registry that exposes Java objects to these scripting language engines.

Bnd is a swiss army knife for OSGi, it creates manifest headers based on analyzing the class code, it verifies the project settings, it manages project dependencies, gives diffs jars, and much more.

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.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the OSGi Core module.

Modello XML Plugin contains shared code for every plugins working on XML representation of the model.
