Apache ACE
  • Apache ACE 0.8.1, released 2011-12-13
When assembling software out of reusable components, the task of deploying software onto an ever increasing number of targets is not trivial to solve. This becomes even harder when these targets require different components based on who's using them. Apache ACE allows you to group those components and assign them to a managed set of targets. This allows you to distribute updates and new components easily, while keeping a full history of what was installed where during what period. It also helps you setup an automated development, QA/testing, staging and production environment.

Apache Beehive
  • Apache Beehive, released 2006-02-13
  • Apache Beehive, released 2006-12-04
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 Celix
Celix is an implementation of the OSGi specification adapted to C. It will follow the API as close as possible, but since the OSGi specification is written primarily for Java, there will be differences (Java is OO, C is procedural). An important aspect of the implementation is interoperability between Java and C. This interoperability is achieved by porting and implementing the Remote Services specification in Celix.

        Apache Crunch
        The Apache Crunch Java library provides a framework for writing, testing, and running MapReduce pipelines. Its goal is to make pipelines that are composed of many user-defined functions simple to write, easy to test, and efficient to run. Running on top of Hadoop MapReduce and Apache Spark, the Apache Crunch™ library is a simple Java API for tasks like joining and data aggregation that are tedious to implement on plain MapReduce. The APIs are especially useful when processing data that does not fit naturally into relational model, such as time series, serialized object formats like protocol buffers or Avro records, and HBase rows and columns. For Scala users, there is the Scrunch API, which is built on top of the Java APIs and includes a REPL (read-eval-print loop) for creating MapReduce pipelines.

        Apache Curator
        New users of ZooKeeper are surprised to learn that a significant amount of connection management must be done manually. For example, when the ZooKeeper client connects to the ensemble it must negotiate a new session, etc. This takes some time. If you use a ZooKeeper client API before the connection process has completed, ZooKeeper will throw an exception. These types of exceptions are referred to as "recoverable" errors. Curator automatically handles connection management, greatly simplifying client code. Instead of directly using the ZooKeeper APIs you use Curator APIs that internally check for connection completion and wrap each ZooKeeper API in a retry loop. Curator uses a retry mechanism to handle recoverable errors and automatically retry operations. The method of retry is customizable. Curator comes bundled with several implementations (ExponentialBackoffRetry, etc.) or custom implementations can be written.

        Apache DataFu consists of two libraries: Apache DataFu Pig is a collection of useful user-defined functions for data analysis in Apache Pig. Apache DataFu Hourglass is a library for incrementally processing data using Apache Hadoop MapReduce. This library was inspired by the prevelance of sliding window computations over daily tracking data. Computations such as these typically happen at regular intervals (e.g. daily, weekly), and therefore the sliding nature of the computations means that much of the work is unnecessarily repeated. DataFu's Hourglass was created to make these computations more efficient, yielding sometimes 50-95% reductions in computational resources.

        Deltacloud contains a cloud abstraction API - whether the Deltacloud classic API, the DMTF CIMI API or even the EC2 API. Each abstraction API works as a wrapper around a large number of clouds, shielding users from their differences. For every cloud provider there is a driver "speaking" that cloud provider's native API, freeing you from dealing with the particulars of each cloud's API.

        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, all in a business process context. 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. In business, we increasingly see blogs and wikis demonstrating utility in problem solving and communications but the real time nature of business process problem solving largely remains untouched by social networking tools. Existing services, while attractive do not scale well and have proven unreliable. This is unacceptable to business which must be 'Always On' and able to support people in their daily working lives. Such applications must therefore be scalable and reliable but also provide a lot more. When solving problems, how good 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.

        HttpCore is a set of low level HTTP transport components that can be used to build custom client and server side HTTP services with a minimal footprint. HttpCore supports two I/O models: blocking I/O model based on the classic Java I/O and non-blocking, event driven I/O model based on Java NIO. The blocking I/O model may be more appropriate for data intensive, low latency scenarios, whereas the non-blocking model may be more appropriate for high latency scenarios where raw data throughput is less important than the ability to handle thousands of simultaneous HTTP connections in a resource efficient manner.

        The Apache Java Enterprise Mail Server (a.k.a. Apache James) is a 100% pure Java SMTP and POP3 Mail server and NNTP News server. We have designed James to be a complete and portable enterprise mail engine solution based on currently available open protocols. James is also a mail application platform. We have developed a Java API to let you write Java code to process emails that we call the mailet API. A mailet can generate an automatic reply, update a database, prevent spam, build a message archive, or whatever you can imagine. A matcher determines whether your mailet should process an email in the server. The James project hosts the Mailet API, and James provides an implementation of this mail application platform API.

        A single Kafka broker can handle hundreds of megabytes of reads and writes per second from thousands of clients. Kafka is designed to allow a single cluster to serve as the central data backbone for a large organization. It can be elastically and transparently expanded without downtime. Data streams are partitioned and spread over a cluster of machines to allow data streams larger than the capability of any single machine and to allow clusters of co-ordinated consumers. Kafka has a modern cluster-centric design that offers strong durability and fault-tolerance guarantees. Messages are persisted on disk and replicated within the cluster to prevent data loss. Each broker can handle terabytes of messages without performance impact.

        Apache Nutch is a highly extensible and scalable open source web crawler software project. Stemming from Apache Lucene, the project has diversified and now comprises two codebases, namely: Nutch 1.x: A well matured, production ready crawler. 1.x enables fine grained configuration, relying on Apache Hadoop data structures, which are great for batch processing. Nutch 2.x: An emerging alternative taking direct inspiration from 1.x, but which differs in one key area; storage is abstracted away from any specific underlying data store by using Apache Gora for handling object to persistent mappings. This means we can implement an extremely flexibile model/stack for storing everything (fetch time, status, content, parsed text, outlinks, inlinks, etc.) into a number of NoSQL storage solutions. Being pluggable and modular of course has it's benefits, Nutch provides extensible interfaces such as Parse, Index and ScoringFilter's for custom implementations e.g. Apache Tika for parsing. Additonally, pluggable indexing exists for Apache Solr, Elastic Search, etc. Nutch can run on a single machine, but gains a lot of its strength from running in a Hadoop cluster

        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.

        Apache Phoenix is a SQL query engine for accessing NoSQL datastores such as Apache HBase. It is accessed as a JDBC driver and enables querying, updating, and managing NoSQL tables through standard SQL. Instead of using map-reduce, Apache Phoenix compiles your SQL query into a series of HBase scans and orchestrates the running of those scans to produce regular JDBC result sets. Direct use of the HBase API, along with coprocessors and custom filters, results in performance on the order of milliseconds for small queries, or seconds for tens of millions of rows.

        Apache Pig
        Apache Pig is a platform for analyzing large data sets that consists of a high-level language for expressing data analysis programs, coupled with infrastructure for evaluating these programs. The salient property of Pig programs is that their structure is amenable to substantial parallelization, which in turns enables them to handle very large data sets. Pig's infrastructure layer consists of a compiler that produces sequences of Map-Reduce programs. Pig's language layer consists of a textual language called Pig Latin, which has the following key properties: * Ease of programming. It is trivial to achieve parallel execution of simple, "embarrassingly parallel" data analysis tasks. Complex tasks comprised of multiple interrelated data transformations are explicitly encoded as data flow sequences, making them easy to write, understand, and maintain. * Optimization opportunities. The way in which tasks are encoded permits the system to optimize their execution automatically, allowing the user to focus on semantics rather than efficiency. * Extensibility. Users can create their own functions to do special-purpose processing.

          Velocity is a Java-based template engine. It permits anyone to use a simple yet powerful template language to reference objects defined in Java code. When Velocity is used for web development, Web designers can work in parallel with Java programmers to develop web sites according to the Model-View-Controller (MVC) model, meaning that web page designers can focus solely on creating a site that looks good, and programmers can focus solely on writing top-notch code. Velocity separates Java code from the web pages, making the web site more maintainable over its lifespan and providing a viable alternative to Java Server Pages (JSPs) or PHP.

          • XMLBeans v1.0.4-jdk1.3, released 2005-02-24
          XMLBeans is a tool that allows you to access the full power of XML in a Java friendly way. The idea is that you can take advantage of the richness and features of XML and XML Schema and have these features mapped as naturally as possible to the equivalent Java language and typing constructs. XMLBeans uses XML Schema to compile Java interfaces and classes that you can then use to access and modify XML instance data. Using XMLBeans is similar to using any other Java interface/class, you will see things like getFoo or setFoo just as you would expect when working with Java. While a major use of XMLBeans is to access your XML instance data with strongly typed Java classes there are also API's that allow you access to the full XML infoset (XMLBeans keeps XML Infoset fidelity) as well as to allow you to reflect into the XML schema itself through an XML Schema Object model. For more details on XMLBeans see the XMLBeans Wiki pages or the XMLBeans documentation (the Documentation tab on this website). What Makes XMLBeans Different There are at least two major things that make XMLBeans unique from other XML-Java binding options. 1. Full XML Schema support. XMLBeans fully supports XML Schema and the corresponding java classes provide constructs for all of the major functionality of XML Schema. This is critical since often times you do not have control over the features of XML Schema that you need to work with in Java. Also, XML Schema oriented applications can take full advantage of the power of XML Schema and not have to restrict themselvs to a subset. 2. Full XML Infoset fidelity.When unmarshalling an XML instance the full XML infoset is kept and is available to the developer. This is critical because because of the subset of XML that is not easily represented in java. For example, order of the elements or comments might be needed in a particular application. A major objective of XMLBeans has been to be applicable in all non-streaming (in memory) XML programming situations. You should be able to compile your XML Schema into a set of java classes and know that 1) you will be able to use XMLBeans for all of the schemas you encounter (even the warped ones) and 2) that you will be able to get to the XML at whatever level is necessary - and not have to resort to multple tools to do this. To accomplish this XMLBeans provides three major APIs: * XmlObject The java classes that are generated from an XML Schema are all derived from XmlObject. These provide strongly typed getters and setters for each of the elements within the defined XML. Complex types are in turn XmlObjects. For example getCustomer might return a CustomerType (which is an XmlObject). Simple types turn into simple getters and setters with the correct java type. For example getName might return a String. * XmlCursor From any XmlObject you can get an XmlCursor. This provides efficient, low level access to the XML Infoset. A cursor represents a position in the XML instance. You can move the cursor around the XML instance at any level of granularity you need from individual characters to Tokens. * SchemaType XMLBeans provides a full XML Schema object model that you can use to reflect on the underlying schema meta information. For example, you might want to generate a sample XML instance for an XML schema or perhaps find the enumerations for an element so that you can display them. All of this was built with performance in mind. Informal benchmarks and user feedback indicate that XMLBeans is extremely fast.

          Xerces-J is a high performance, fully compliant validating XML parser written in Java. It is a fully conforming XML Schema processor that includes a complete implementation of the Document Object Model Level 3 Core and Load/Save W3C Recommendations and provides a complete implementation of the XML Inclusions (XInclude) W3C Recommendation. It also provides support for OASIS XML Catalogs v1.1. Xerces 2.x introduced the Xerces Native Interface (XNI), a complete framework for building parser components and configurations that is extremely modular and easy to program. XNI is merely an internal set of interfaces. There is no need for an XML application programmer to learn XNI if they only intend to interface to the Xerces2 parser using standard interfaces like JAXP, DOM, and SAX. Xerces developers and application developers that need more power and flexibility than that provided by the standard interfaces should read and understand XNI. The latest version released, 2.11.0, expands on Xerces' experimental support for XML Schema 1.1 by providing implementations for the simplified complex type restriction rules (also known as subsumption), xs:override and a few other XML Schema 1.1 features. This release also introduces experimental support for XML Schema Component Designators (SCD). It fixes several bugs which were present in Xerces-J 2.10.0 and also includes a few other minor enhancements.

          XML::Xerces is the Perl API to the Apache project's Xerces XML parser. It is implemented using the Xerces C++ API, and it provides access to most of the C++ API from Perl. Because it is based on Xerces-C, XML::Xerces provides a validating XML parser that makes it easy to give your application the ability to read and write XML data. Classes are provided for parsing, generating, manipulating, and validating XML documents.

The parser provides high performance, modularity, and scalability, and provides full support for Unicode. XML::Xerces implements the vast majority of the Xerces-C API (if you notice any discrepancies please mail the list). The exception is some functions in the C++ API which either have better Perl counterparts (such as file I/O) or which manipulate internal C++ information that has no role in the Perl module. The majority of the API is created automatically using Simplified Wrapper Interface Generator (SWIG). However, care has been taken to make most method invocations natural to perl programmers, so a number of rough C++ edges have been smoothed over (See the Special Perl API Features section).

          Apache mod_ftp
          • Current 0.9 release, released 2008-10-08
          mod_ftp is an FTP Protocol module to serve httpd content over the FTP protocol (whereever the HTTP protocol could also be used). It provides both RETR/REST retrieval and STOR/APPE upload, using the same user/permissions model as httpd (so it shares the same security considerations as mod_dav plus mod_dav_fs).
