Apache ESME (Enterprise Social Messaging Environment) is a secure and highly scalable microsharing and micromessaging platform that allows people to discover and meet one another and get controlled access to other sources of information.
You can hardly turn a web page these days without seeing a story that describes how people are using social networks, whether it is Twitter, Facebook or some other service to develop and build their personal communities.
When solving problems, how useful might it be if a user was able to tap into the collective knowledge of her peers or surrounding groups of people with whom she might naturally network in the workplace setting? How much quicker and with greater precision might she be able to solve daily problems? What if there was a communications mechanism that takes the best of what services like Twitter offers and co-mingled that with readily recognizable business processes? That solution is Apache ESME.
Welcome to Apache Isis Apache Isis is a full-stack open source application development framework, designed to let you rapidly develop domain-driven business enterprise applications. The framework is designed around two patterns: * the first is the naked objects pattern, whereby the framework automatically generates an object-oriented user interface (OOUI) for your domain objects. If required, this OOUI can then be customized. * the second is the hexagonal architecture. This means it allows the same domain model to be run with different viewers, either as a desktop app or as a webapp. Equally, you can choose which object store to use in order to persist your domain objects. The diagram below shows the hexagonal architecture as it is implemented by Apache Isis.
MINA is a simple yet full-featured network application framework which provides:
* Unified API for various transport types:
o TCP/IP & UDP/IP via Java NIO
o Serial communication (RS232) via RXTX
o In-VM pipe communication
o You can implement your own!
* Filter interface as an extension point; similar to Servlet filters
* Low-level and high-level API:
o Low-level: uses ByteBuffers
o High-level: uses user-defined message objects and codecs
* Highly customizable thread model:
o Single thread
o One thread pool
o More than one thread pools (i.e. SEDA)
* Out-of-the-box SSL · TLS · StartTLS support using Java 5 SSLEngine
* Overload shielding & traffic throttling
* Unit testability using mock objects
* JMX managability
* Stream-based I/O support via StreamIoHandler
* Integration with well known containers such as PicoContainer and Spring
* Smooth migration from Netty, an ancestor of Apache MINA.
Apache Shiro is a powerful and easy-to-use security framework that performs authentication, authorization, cryptography, and session management. With Shiro’s easy-to-understand API, you can quickly and easily secure any application – from the smallest mobile applications to the largest web and enterprise applications.
Apache Tika is a toolkit for detecting and extracting metadata and structured text content from various documents using existing parser libraries. You can find the latest release on the download page. See the Getting Started guide for instructions on how to start using Tika.
Apache PDFBox is an open source Java PDF library for working with PDF documents. This project allows creation of new PDF documents, manipulation of existing documents and the ability to extract content from documents. Apache PDFBox also includes several command line utilities. Apache PDFBox is published under the Apache License v2.0
Sqoop is a tool designed to import data from relational databases into Hadoop. Sqoop uses JDBC to connect to a database. It examines each table’s schema and automatically generates the necessary classes to import data into the Hadoop Distributed File System (HDFS). Sqoop then creates and launches a MapReduce job to read tables from the database via DBInputFormat, the JDBC-based InputFormat. Tables are read into a set of files in HDFS. Sqoop supports both SequenceFile and text-based target and includes performance enhancements for loading data from MySQL.

What is Apache Pivot?
Apache Pivot is an open-source platform for building rich internet applications in Java. It combines the enhanced productivity and usability features of a modern RIA toolkit with the robustness of the Java platform. Pivot applications are written using a combination of Java and XML and can be run either as an applet or as a standalone, optionally offline, desktop application.
Like other modern development platforms, Pivot provides a comprehensive set of foundation classes that together comprise a "framework". These classes form the building blocks upon which more complex and sophisticated applications can be built.
Apache Wink is a simple yet solid framework for building RESTful Web services. It is comprised of a Server module and a Client module for developing and consuming RESTful Web services.
The Wink Server module is a complete implementation of the JAX-RS v1.0 specification. On top of this implementation, the Wink Server module provides a set of additional features that were designed to facilitate the development of RESTful Web services.
The Wink Client module is a Java based framework that provides functionality for communicating with RESTful Web services. The framework is built on top of the JDK HttpURLConnection and adds essential features that facilitate the development of such client applications.
WSRP is an open standard proposed by OASIS for several years. The spec now is sponsored by a number of
big names like IBM and BEA. There are currently two active implementation of the spec. One is wsrp4j from
Apache foundation (still a incubator project, been developed since 2002). The other one is a subproject of
dev.java.net Open-Portal.
I have been exposed and done lot of development on the Apache's wsrp4j project. Thus, in this guide I will
mainly discuss wsrp4j implementation.
At this point, wsrp4j project is still under heavy development and re-construction. It is almost impossible
to get the trunk snapshot in the project repository and make it work without pulling all your hair out to figure
out how to set it up properly. This mostly caused by the lack of documentation and support from its developers.
Still, there is a stable (enough) revision which we can use to make a perfect wsrp4j environment.
The wsrp4j revison I use here is 440430 along with pluto portal 1.0.1 release for setting up a producer.
Jetspeed 2.1 (latest version currently) will be used as a container for wsrp4j consumer (wsrp4j-proxyportlet).
Of course, you can use pluto to setup wsrp4j consumer as well. But that is very easy to do.
Plus, pluto portal doesn't provide a lot of bell and whistle in the GUI side as Jetspeed portal does.
Pivot is an open-source platform for building rich internet applications in Java. It combines the enhanced productivity and usability features of a modern RIA toolkit with the robustness of the industry-standard Java platform.
Pivot applications are written using a combination of Java and XML and can be run either as an applet or as a standalone (optionally offline) desktop application. While Pivot was designed to be familiar to web developers who have experience building AJAX applications using HTML, CSS, and JavaScript, it provides a much richer set of standard widgets than HTML, and allows developers to create sophisticated user experiences much more quickly and easily. Pivot will also seem familiar to Swing developers, as both Swing and Pivot are based on Java2D and employ a model-view-controller (MVC) architecture to separate component data from presentation. However, Pivot includes additional features that make building modern GUI applications much easier, including declarative UI, data binding, effects and transitions, and web services integration.
This is the Wiki for the Pivot project. It includes a collection of demos as well as a tutorial introduction to the platform:
This Pure-Java library reads & writes a variety of image formats, including fast parsing of image info (size, color space, icc profile, etc.) and metadata.
This library is pure Java. It's slow, consequently, but perfectly portable. It's easier to use than ImageIO/JAI/Toolkit (Sun/Java's image support), supports more formats (and supports them more correctly). It also provides easy access to metadata.
Although not yet version 1.0, sanselan is working and is used by a number of projects in production.
Olio is a is a web2.0 toolkit to help evaluate the suitability, functionality and performance of web technologies. Olio defines an example web2.0 application ( an events site somewhat like yahoo.com/upcoming) and provides three initial implementations : PHP, Java EE and RubyOnRails (ROR). The toolkit also defines ways to drive load against the application in order to measure performance.
We encourage alternate implementations of the application by either completely re-writing the application using a different language (say python), higher-level frameworks (such as CakePHP)
