The Java Content Repository (JCR) standard, which is based on the Java Specification Requests JSR170 (version 1.0) and JSR 283 (version 2.0), provides a Java-centric object-oriented storage API specifically targeted at content management scenarios. The JCR is not a content management system or a full-fledged content management system API, but rather a content repository API. A content repository provides a common API for all content-driven applications and CMS components, which require access to the content. It provides methods to read, write, and query content. The primary motivation of the JCR standard is to provide a standard and vendor-neutral programmatic interface for content repositories, allowing applications of multiple vendors to interact efficiently.

" Given that web service invocations are always remote across the internet, developing rigorous and responsive web service client applications has always been a challenge for architects and developers working with SOA. JAX-WS 2.0 comes with one effective solution to this problem: asynchronous web service invocation, with which a web service client may interact with a web service in a non-blocking, asynchronous approach. In this article, we will provide an exposition of this technology with examples built upon the reference implementation. Our examples utilize JDK 5.0, JAX-WS 2.0 reference implementation (RI), and Tomcat 5.5. JAX-WS 2.0 requires JAXP 1.3. To replace the JAXP 1.2 released with JDK 5.0 with this newer version, one approach is to download the JAXP 1.3 RI, and copy the endorsed directory under /lib of its installation home to %JAVA_HOME%/jre/lib. We need to copy the jaxp-api.jar of JAXP 1.3 RI to %JAVA_HOME%/jre/lib/endorsed as well. To make Tomcat 5.5 work with JAX-WS 2.0, readers need to copy all the .jar files under the /lib directory of the JAX-WS 2.0 RI installation to the %CATALINA_HOME%/shared/lib directory. As of this writing (in addition to Tomcat 5.5), Sun Java System Application Server 9.0, GlassFish, and Celtix also support JAX-WS 2.0. xFire is in the process of completing its implementation of this specification. Since asynchronous web service invocation in JAX-WS 2.0 is built upon the concurrent programming support in JDK 5.0 introduced with the java.util.concurrent package, we will start from there."

Setting up an infrastructure for Instant Messaging" article series. In my previous tutorials, I showed you how to setup the Openfire IM Server and how to configure the Spark client in order to connect to that server. In this tutorial, I will show you how to add XMPP messaging capabilities to your own application. I will use the Smack library, an Open Source XMPP (Jabber) client library for instant messaging and presence. Smack is a pure Java library and can be embedded into your applications to create anything from a full XMPP client to simple XMPP integrations.

"The Virgo Web Server from EclipseRT is a completely module-based Java application server that is designed to run enterprise Java applications and Spring-powered applications with a high degree of flexibility and reliability. It offers a simple yet comprehensive platform to develop, deploy, and service enterprise Java applications. The Virgo kernel supports the core concepts of Virgo and is not biased towards the web server, thus enabling other types of server to be created. The kernel can also be used stand-alone as a rich OSGi application platform. A server runtime can easily be constructed by deploying suitable bundles on top of the kernel. "

This article explains how to develop RESTful web services in Java with the JAX-RS reference implementation Jersey. In this article Eclipse 3.5, Java 1.6, Tomcat 6.0 and JAX-RS 1.1. (Jersey 1.1.5) is used.
