Author: The Apache Software Foundation

Latest version: 2.2.1
Added 2005-01-10Updated 2009-09-14

Java project management and project comprehension tool.
Maven is based on the concept of a Project Object Model (POM) in that all the artifacts produced by Maven are a result of consulting a well-defined model for your project.
Features include:
- Development and management of your project are controlled from the project model (builds, documentation, source metrics, source cross-references and several reports).
- A single set of methods are used to build any number of projects that you are managing.
- Integration with Gump, a tool used at Jakarta to help projects maintain backward compatibility with their clients.
- Site publication based on the POM. Once the POM is accurate your developers can publish the project's content. Maven provides the following: Change log document created directly from repository information; Cross referenced sources; Source metrics; Mailing lists; Developer list; Dependency list; Unit test reports including coverage; Article Collection; Software Development References; Software Development Process Documentation; and more reports using the different plugins.

Jar Jar Links

Home Page

Categories: Miscellaneous

Latest version: 1.0rc5
Added 2007-09-09

Utility for repackaging Java libraries and embed them into your own distribution. This is useful for two reasons:
- You can ship a single jar file with no external dependencies.
- You can avoid problems where your library depends on a specific version of a library, which may conflict with the dependencies of another library.

How does it work?

Jar Jar Links includes an Ant task that extends the built-in jar task. The normal zipfileset element is used to embed jar files. A new rule element is added which uses wildcards patterns to rename the embedded class files. Bytecode transformation (via ASM) is used to change references to the renamed classes, and special handling is provided for moving resource files and transforming string literals.

Latest version: 1.2
Added 2005-04-11

ActiveCluster is a framework for writing cluster-based applications, monitoring the available nodes in a cluster and communicating with them. ActiveCluster consists of an API together with a default implementation.

The API reuses a few of the standard JMS APIs for Message, Destination, MessageListener and adds a few simple interfaces for working with clusters representing nodes in the cluster, replicated node state and listeners to nodes joining, leaving or updating their state.

The current features include
* viewing the current nodes in the cluster and their current state
* listening to nodes arrive, update their state, shut down or fail
* communicate with the cluster as a whole or with any specific node in the cluster
* elect a leader of the cluster to make decisions on behalf of the cluster

Latest version: 2.0
Added 2005-06-14

PooliT is a Java object pooling library capable of pooling any type of Java object. Pooling objects can increase program performance and avoid the overhead of object creation. Good candidates for pooling are classes that have costly instantiation routines, like database connections or sockets. By conserving and re-using these objects, you save processor cycles creating new objects and also alleviate the garbage collector from having to reclaim them up after use.

JEF

Home Page

Categories: Frameworks, Miscellaneous

Latest version: 0.4.1
Added 2005-09-22

JEF, acronym for Java Evolutionary Framework, is a project aimed to both define and implement a genetic programming framework for the Java programming language.
JEF has been conceived as divided into three subprojects, namely: Dna, Jef and JXTA-Jef :

Dna: this is the basic building block for the JEF Proj since it provides a framework for dynamically manipulating Java class files. Amongst all the possibilities, this package allows developers to obtain object oriented Java class files representations, modify them according to their own needs up to the bytecode level (thus removing, adding or modifying the bytecode of already existing methods), add brand new methods to already existing classes, or even programmatically create new classes completely from scratch, validate newly created class files according to the constraints imposed by the Official Java Class File Specification, all by means of an easy to use/understand and well defined API characterized by a rapid learning curve.

Jef: the Jef subproject is meant to define the interfaces as well as some basic implementations of all those classes involved in the process of mixing two Java class files in order to generate a potentially brand new implementation, according to a customizable logic. This subproject is aimed to provide both demonstrative Mixer implementations and implementations useful to be deployed either directly or to be used as starting point for customized Mixer implementations. In the latter case developers will be berived of the burden of taking care of how some complex functionalities should be implemented, relying upon well tested and working implementations.

JXTA-Jef: deploying the Jef-Dna framework over a number of somehow interconnected computing-capable nodes, will enable us to let heterogeneous Java class files (i.e. mobile agents, teleo-reactive agents, etc.) move from one node to another, and potentially evolve with a really low degree of human interaction. This subproject is therefore necessary for building a decentralized (P2P - peer to peer) overlay network gathering Jef-capable nodes.

Latest version: 2.6-stable0
Added 2007-02-15Updated 2008-04-08

Java infrastructure software that allows you to scale your application to as many computers as needed, without expensive custom code or databases.
Terracotta is an open source clustering solution that provides transparent clustering and coordination services.

Features include:
- Heap-Level replication: selectively share object graphs across the cluster.
- Cross-JVM coordination.
- Large virtual heaps: manage heaps that are much bigger than what can be contained in a single JVM.
- Fine-grained changes: Terracotta does not use serialization, and therefore can push field-level changes to the cluster. This translates into better network efficiency for replication.
- Runtime management and control: view in real-time objects in the heap.
- No serialization: because Terracotta clusters at the JVM level, no serialization code is required.
- Cluster-wide locking semantics: distributed wait/notify and synchronized.

You can have unsigned features - features that are not used in the signature generation/verification and therefore can change their values leaving the license valid. Also the library provides methods for signing arbitrary content that should not be changed by the user.

Latest version: 4.4

Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types.

Dozer supports simple property mapping, complex type mapping, bi-directional mapping, implicit-explicit mapping, as well as recursive mapping. This includes mapping collection attributes that also need mapping at the element level.
The mapper is used any time you need to take one type of Java Bean and map it to another type of Java Bean. Most field mapping can be done automatically by Dozer using reflection, but any custom mapping can be predescribed in XML format. Mapping is bi-directional so only one relationship between classes needs defining. If any property names on both objects are the same you do not even need to do any explicit property mapping for these fields.

Features include:
- Context based mapping
- Collection and Array mapping handling Lists, Sets, Arrays and allowing for class type hints
- Support for custom converters
- Custom bean factories for beans that do not follow the JavaBean specification
- Inheritance mapping including abstract classes and interfaces
