When it comes to web services interoperability between .NET and Java, the choice used to be limited to SOAP over HTTP. Two new options recently became available in this area: WebSphere MQ (WMQ) and ActiveMQ transports can now be used for building interoperable web services between Java and .NET.
CXF is a fully featured Open Source Web Services Framework which people claim is easy to use and is industrial strength. CXF is also embeddable and people have used it often in combination with Spring. CXF is the combination of the Celtix and XFire communities coming together at Apache.
In one of the most entertaining presentations on the topic ever, Dr. Jim Webber debunks myths about the mainstream ESB concept and explains how a lightweight approach can yield real benefits without giving in to vendor pressure. Jim claims that an ESB often ends up being just a thin veneer on an existing mess, and how an approach that doesn't put intelligence into the network is superior.
A new article by Eran Chinthaka, Develop asynchronous Web services with Axis2, provides several examples of using the asynchronous APIs of Axis2 in client and server side applications.
KonaKart, a free Java-based online shopping cart, just released version 184.108.40.206. InfoQ spoke with KonaKart founder Paolo Sidoli to learn more about this release, and how KonaKart fits into the online shopping cart space.
Noemax releases a SOAP/TCP transport implementation for WCF, which makes use of the Fast Infoset in order to improve performance and interoperability of WCF services.
InfoQ's Stefan Tilkov questioned lead developers of Apache Axis2, Apache CXF, Spring Web Services, JBossWS and and Sun’s Metro about their design goals, their approach towards Java and Web services standards, data binding, accessing XML, interoperability, REST support, and framework maturity. The results revealed many similarities and some noteworthy differences.
In this presentation, recorded at the No Fluff Just Stuff Symposium, Scott Davis provides a pragmatic, down-to-earth introduction to Web services as used in the real world by public sites, including SOAP-based, REST and POX-style examples. While the buzzword density leaves nothing to be desired, the presentation contains a very accessible introduction to the core Web services standards.
Apache Geronimo, an open-source Java Enterprise Edition (Java EE) application server, recently released version 2.0.1. InfoQ took the opportunity to learn more about Apache Geronimo and where it fits into the application server space.
In this InfoQ interview, recorded at QCon London, Jim Webber, ThoughtWorks SOA practice leader talks to Stefan Tilkov about Guerilla SOA, a lightweight approach to SOA that does not rely on big middleware products, a message-oriented architectural style called MEST and its differences to REST, and the SOAP Service Description Language (SSDL).
In an InfoQ interview, recorded at QCon London, Anne Thomas Manes, research director at Burton Group, talks about the state of SOA, explains different ways of getting funding for SOA initiatives, the value of SOA governance and governance tools. Another topic covered is the applicability of REST to SOA, the need for a RESTful description language, and REST support in SOAP toolkits.
The topic of REST as an alternative for integration has been debated on InfoQ many times before. Recent news suggest REST is now gaining mind share among analysts and vendors, with some seeing REST as "the next big thing".
Dan Diephouse has posted a paper, titled "Navigating WS-*", that provides an excellent overview of Web services standards and their respective relevance for solving real-world problems.
enunciate 1.0, a J2EE web service deployment framework that provides a complete development-to-deployment system for creating SOAP, REST, and JSON endpoints, was released last week. enunciate is not a web service stack like Axis2 or XFire. Rather, it uses XFire and Spring to provide a code-first development model (not in itself novel) that enforces compatibility contracts at compile time.
Deepal Javasinghe, one of the developers of Apache Axis2 and Synapse, describes 6 major usability improvements introduced in Axis2: J2EE style deployment mechanism, Hot deployment and hot update, a repository (where you drop services and modules, Change in the deploying of handlers (modules), new deployment descriptors, and multiple deployment options.
