The Apache Software Foundation has resigned its seat on the Java SE/EE Executive Committee. Apache has served on the EC for the past 10 years, winning the JCP "Member of the Year" award 4 times, and recently was ratified for another term with support from 95% of the voting community. Further, the project communities of the ASF, home to Apache Tomcat, Ant, Xerces, Geronimo, Velocity and nearly a 100 mainstay java components have implemented countless JSRs and serve on and contribute to many of the JCPs technical expert groups. We'd like to provide some explanation to the community as to why we're taking this significant step.

Inter Thread Communication is one of the distinct facility in multi threading application development of java. In real world Inter Thread communication based applications of java works faster when compared to all the other applications in java. Inter-thread communication is all about making synchronized threads communicate with each other. It is a mechanism in which a thread is paused running in its critical section and another thread is allowed to enter in the same critical section to be executed. It is implemented by following methods of Object class wait() : Tells the calling thread to give up monitor and go to sleep until some other thread enters the same monitor and call notify. Causes current thread to release the lock and wait until either another thread invokes the notify() method or the notifyAll() method for this object, or a specified amount of time has elapsed. The current thread must own this object's monitor.

Shrinkwrap provides a simple mechanism to assemble archives like JARs, WARs, and EARs with a friendly, fluent API. JavaArchive archive = ShrinkWrap.create(JavaArchive.class,"archive.jar")    .addClasses(MyClass.class,MyOtherClass.class)    .addResource("mystuff.properties"); From there you may deploy directly into any supported integration container like JBoss EmbeddedAS, GlassFish v3 Embedded, Jetty, or OpenEJB.  Or perhaps you'd like to export the archive to a file or exploded directory structure.  Maybe you'd prefer to serialize it over the network to a remote host.  The possibilities are limitless. To boot, ShrinkWrap is the supported deployment mechanism of the Arquillian project, and together we render the testing of true enterprise components amiable as a puppy.  Where Java EE brought a POJO programming model to application development, we've brought it to testing.  You handle your business logic; we'll do the rest. To foster community participation, the majority of documentation and examples are available through our Wiki. Releases are available either via our Downloads section, or through the JBoss Maven Repository, which we recommend is configured in ${userHomeDir}/.m2/settings.xml:

"In todays business environment data corruption can have serious consequences for the enterprise including service unavailability, system reconciliation costs, and damage to customer relationships and business reputation. The JBoss Transaction Service (JBossTS) protects businesses from data corruption by guaranteeing complete, accurate business transactions for Java based applications (including those written for the JEE and EJB frameworks) thereby eliminating the risks and costs associated with time-consuming manual reconciliation following failures."

The project aims to integrate the Google Web Toolkit (GWT) and the Dojo framework. Indeed the Dojo framework is very rich in term of widgets and utilities (fisheye, slider, drag and drop functionality) and the main interest is to take benefits of the huge work which has been already done by the Dojo community. In other words, it means: the Dojo widgets become GWT widgets, the Dojo utilities become GWT helper.

Spring Security is a powerful and highly customizable authentication and access-control framework. It is the de-facto standard for securing Spring-based applications Spring Security is one of the most mature and widely used Spring projects. Founded in 2003 and actively maintained by SpringSource since, today it is used to secure numerous demanding environments including government agencies, military applications and central banks. It is released under an Apache 2.0 license so you can confidently use it in your projects. Spring Security is also easy to learn, deploy and manage. Our dedicated security namespace provides directives for most common operations, allowing complete application security in just a few lines of XML. We also offer complete tooling integration in SpringSource Tool Suite, plus our Spring Roo rapid application development framework. The Spring Community Forum and SpringSource offer a variety of free and paid support services. Spring Security is also integrated with many other Spring technologies, including Spring Web Flow, Spring Web Services, SpringSource Enterprise, SpringSource Application Management Suite and SpringSource tc Server.

"Executing external processes from Java is a well-known problem area. It is inheriently platform dependent and requires the developer to know and test for platform specific behaviors, for example using cmd.exe on Windows or limited buffer sizes causing deadlocks. The JRE support for this is very limited, albeit better with the new Java SE 1.5 ProcessBuilder class. Reliably executing external processes can also require knowledge of the environment variables before or after the command is executed. In J2SE 1.1-1.4 there is not support for this, since the method, System.getenv(), for retriving environment variables is deprecated. There are currently several different libraries that for their own purposes have implemented frameworks around Runtime.exec() to handle the various issues outlined above. The proposed project should aim at coordinating and learning from these initatives to create and maintain a simple, reusable and well-tested package. Since some of the more problematic platforms are not readily available, it is my hope that the broad Apache community can be a great help."

Arquillian enables you to test your business logic in a remote or embedded container. Alternatively, it can deploy an archive to the container so the test can interact as a remote client. The mission of the Arquillian project is to provide a simple test harness that abstracts away all container lifecycle and deployment from the test logic so developers can easily produce a broad range of integration tests for their enterprise Java applications. Arquillian is part of the JBoss Testing initiative, an umbrella project focused on providing a comprehensive testing tool set for application developers. Arquillian can either execute a test case inside the container, in which case the test class is deployed by Arquillian along with the code under test, or hold back the test class so it can act as a remote client to the deployed code. All the developer has to do is write the test logic. In short... Arquillian makes integration testing a breeze!

Weld is the reference implementation (RI) for JSR-299: Java Contexts and Dependency Injection for the Java EE platform (CDI). CDI is the Java standard for dependency injection and contextual lifecycle management, led by Gavin King for Red Hat, Inc. and is a Java Community Process (JCP) specification that integrates cleanly with the Java EE platform. Any Java EE 6-compliant application server provides support for JSR-299 (even the web profile). Weld and the JSR-299 TCK (Technology Compatibility Kit) are developed here at seamframework.org. Both are licensed under the Apache License, Version 2.0.

"http://www.atompub.org/ defines a simple interface over HTTP to publish and subscribe to artifacts (files) and collections of artifacts (services/packages). AtomPub interface serves following purposes: 1: provide "feeds" for people/systems to monitor for changes: For example, user subscribes to a feed which lists contents of package or user subscribes to feed which lists changed contents in a package 2. provide the default remote api to push/pull content and meta data from the repository. This allows other applications to integrate with Guvnor by accessing repository content via atom pub programmatically."

" Further talk about the overall approach to REST access in the Guvnor project expanded from the JIRA issue, ad hoc discussions on the dev list to Jevis Liu's "AtomPub Interface for Guvnor" proposal on the Drools community wikI. Taking off from where Michael Neale's original "Guvnor AtomPub Interface" started in 2008 and expanding into categories, metadata and other return types, this page became a rough, but working implementation specification.

The goal of the Eclipse Scout project is making it easy to build distributed enterprise applications based on the Eclipse platform. It consists of a runtime framework providing transparent service communication between the client and backend part and is shipped with a rich set of common user interface components. The user interface is not built for a particular rendering technology but it encapsulates the core functionality into a headless model. GUI factories are available for rendering the client model into a particular target UI platform. SWT and Swing are supported out of the box and an AJAX GUI factory could be easily added. Developing Scout applications is supported by the Scout SDK, a plug-in set built on top of Eclipse PDE and Eclipse JDT. The Scout SDK works directly on the bare Java resources and assists the development task by providing an augmented view on the underlying Java code. Additionally, it comes with a rich set of wizards and operations for modifying the Scout application project just by editing the underlying Java code. There is no meta-data required. Hence a developer can switch between editing resources using Eclipse's standard editors and leveraging the features of Scout SDK at any point in time. Eclipse Scout can be used to create multi-tier client/server applications, standalone client applications or OSGi-based server applications. Basically, there are three main advantages when choosing Scout as your framework for building such applications. First, the Scout runtime is service oriented by design. Almost every functionality is provided as an OSGi service. Every OSGi bundle may make use of them. Second, Scout provides a rich set of UI elements being uncoupled from a particular GUI technology. And third, building distributed client/server applications is as easy as if both parts would run within the same local JVM.

Ajax Push enables real-time collaborative applications, based on a mechanism call ICEpush. Check out the Ajax Push overview before delving into the API. ICEpush Library - icepush.jar To enable Ajax Push with ICEfaces 2, you simply include the icepush.jar library with your application.

Ajax Push allows the application to incrementally update any part of the page at any time, for any group of clients. This is a small change in terms of the technical capabilities of Ajax applications, but it is a revolutionary change in terms of what applications can actually provide to users. Ajax Push is the key to building collaborative multi-user applications for the web. Under the Hood The intricacies of the Ajax Push implementation are completely transparent to the ICEfaces developer, as you work with a straightforward set of APIs. It is, however, useful to understand the basic mechanics. Ajax Push in ICEfaces 2.0 leverages an asynchronous notification mechanism call ICEpush. Simply put, ICEpush uses long polling to provide asynchronous notification over standard HTTP, using only standard browser capabilities. The sequence of events involved in Ajax Push is illustrated below.
