PMC: Apache cTAKESApache CuratorNew 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 takessome 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 simplifyingclient 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 retryoperations. The method of retry is customizable.

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 attractivedo 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 solvingproblems, 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 ableto 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.Categories: content

PMC: Apache XercesApache Xerces for Java XML ParserXerces-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 W3CRecommendations 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 parsercomponents 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 standardinterfaces 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' experimentalsupport 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 ComponentDesignators (SCD). It fixes several bugs which were present in Xerces-J 2.10.0 and also includes a few other minor enhancements.Categories: xml

PMC: Apache XercesApache Xerces for Perl XML ParserXML::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 validatingXML 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. XML::Xerces is faithful to the XML 1.0 and 1.1 recommendations and associatedstandards (DOM levels 1, 2, and 3, SAX 1 and 2, Namespaces, and W3C XML Schema). 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 younotice 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 theAPI 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 Featuressection).

PMC: Apache AtticApache XML Commons ExternalThe 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. Whilewe 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 versioncontrol; 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.Categories: xml

PMC: Apache XML GraphicsApache XMLBeansXMLBeans 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 possibleto 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 willsee 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 (XMLBeanskeeps 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).WhatMakes XMLBeans DifferentThere 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 majorfunctionality 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 haveto 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 intoa 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 dothis.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 anyXmlObject 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 charactersto 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 enumerationsfor 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.Categories: xml
