Apache Synapse
Apache Synapse is a simple and highly effective Web Services intermediary and SOA framework. It can be
added to your existing network very simply either as a services gateway or as an HTTP proxy. Once Apache
Synapse is mediating your service requests it can perform many functions including routing, load-balancing,
transformation and protocol switching. Apache Synapse can be used to build an Enterprise Service Bus (ESB) or
Service Oriented Architecture (SOA).
Apache Synapse has been designed to support very fast XML routing with a streaming XML design based upon
Apache Axiom. in addition, the use of a completely asynchronous architecture and non-blocking IO based on Java NIO
ensures that Synapse has very low overhead and can scale to support thousands of concurrent clients without dropping
messages.

The application can then be easily moved to any JDBC-capable database. In addition to management of persistent Java objects mapped to relational databases, Cayenne provides a plethora of features including single method call queries and updates (including atomic updates of all modified objects), seamless integration of multiple databases into a single virtual data source, three tier persistence with caching on the remote client, paging of results, record locking, and many more features. JPA compliance is in progress.

Apache Beehive
Our goal is to make J2EE programming easier by building a simple object model on J2EE and Struts. Using Java 5 annotations, Beehive reduces the coding necessary for J2EE. The initial Beehive project has three pieces.
NetUI: An annotation-driven web application programming framework that is built atop Struts. NetUI centralizes navigation logic, state, metadata, and exception handling in a single encapsulated and reusable Page Flow Controller class. In addition, NetUI provides a set of JSP tags for rendering HTML / XHTML and higher-level UI constructs such as data grids and trees and has first-class integration with JavaServer Faces and Struts.
Controls: A lightweight, metadata-driven component framework that reduces the complexity of being a client of enterprise resources. Controls provide a unified client abstraction that can be implemented to access a diverse set of enterprise resources using a single configuration model.
Web Service Metadata (WSM): An implementation of JSR 181 which standardizes a simplified, annotation-driven model for building Java web services.
In addition, Beehive includes a set of system controls that are abstractions for low-level J2EE resource APIs such as EJB, JMS, JDBC, and web services.

Apache Cayenne
Cayenne is a powerful, full-featured, opensource framework created for developers working with relational databases. it seamlessly maps any relational database to Java objects, reducing development time and adding considerable functionality to any application which requires a database. Developers using Cayenne will be able to concentrate on the core business requirements and the data model instead of the SQL details. The application can then be easily moved to any JDBC-capable database. In addition to management of persistent Java objects mapped to relational databases, Cayenne provides a plethora of features including single method call queries and updates (including atomic updates of all modified objects), seamless integration of multiple databases into a single virtual data source, three tier persistence with caching on the remote client, paging of results, record locking, and many more features. JPA compliance is in progress.

Apache Cocoon
Apache Cocoon is a web development framework built around the concepts of separation of concerns (making sure people can interact and collaborate on a project, without stepping on each other toes) and component-based web development. Cocoon implements these concepts around the notion of "component pipelines", each component on the pipeline specializing on a particular operation. This makes it possible to use a "building block" approach for web solutions, hooking together components into pipelines without any required programming.

Turbine is a matured and well established framework that is used as the base of many other projects (like e.g. the excellent Jetspeed 1 Portals framework.
Turbine is an excellent choice for developing applications that make use of a services-oriented architecture. Some of the functionality provided with Turbine includes a security management system, a scheduling service, XML-defined form validation server, and an XML-RPC service for web services. It is a simple task to create new services particular to your application.
The Turbine core is free of any dependency on a presentation layer technology. Both JavaServer Pages (JSP) and Velocity are supported inside Turbine. For developers already familiar with JSP, or have existing JSP tag libraries, Turbine offers support for the Sun standard. Velocity is the favorite view technology of most users of the Turbine framework; try it out and see if Velocity can help you develop your web applications faster and work more easily with non-programming designers.
Turbine is developed in an open, participatory environment and released under the Apache Software License. Turbine is intended to be a collaboration of the best-of-breed developers from around the world. We invite you to participate in this open development project.

Apache ODE (Orchestration Director Engine) executes business processes written following the WS-BPEL standard. It talks to web services, sending and receiving messages, handling data manipulation and error recovery as described by your process definition. It supports both long and short living process executions to orchestrate all the services that are part of your application.
WS-BPEL is an XML-based language defining several constructs to write business processes. It defines a set of basic control structures like conditions or loops as well as elements to invoke web services and receive messages from services. It relies on WSDL to express web services interfaces. Message structures can be manipulated, assigning parts or the whole of them to variables that can in turn be used to send other messages.

transformation and protocol switching. Apache Synapse can be used to build an Enterprise Service Bus (ESB) or
Service Oriented Architecture (SOA).
Apache Synapse has been designed to support very fast XML routing with a streaming XML design based upon
Apache Axiom. in addition, the use of a completely asynchronous architecture and non-blocking IO based on Java NIO
ensures that Synapse has very low overhead and can scale to support thousands of concurrent clients without dropping
messages.

Apache XML Commons External
The External components portion of Apache XML Commons contains interfaces that are defined by external standards organizations. For DOM, that's the W3C; for SAX it's David Megginson (http://www.saxproject.org); for JAXP it's Sun. While we could send users to each of the primary sources for these deliverables, keeping our own versions of these in the XML Commons repository gives us a number of advantages: 1) Simplicity of downloads; users get the whole product from one place, 2) Better version control; we can only take fixes we want and add Apache-specific changes, 3) Better overview documentation of how these interfaces fit into the XML processing world, 4) More chance for cross-project community building within Apache projects.
-
Apache XML Commons Resolver
The XML Commons Resolver can be used in a wide variety of XML parsing, processing and related programs to resolve various public or system identifiers into accessible URLs for use by your application. The resolver supports several catalog types for mapping, including OASIS XML, OASIS TR 9401 and XCatalog styles.
