Structural design patterns are design patterns that ease the design by identifying a simple way to realize relationships between entities. Let's discover some structural patterns used by JBoss.

One subtask of the JDK migration from the legacy bug tracking system to JIRA was reclassifying bugs from a three-level taxonomy in the legacy system, (product, category, subcategory), to a fundamentally two-level scheme in our customized JIRA instance, (component, subcomponent). In the JDK JIRA system, there is technically a third project-level classification, but by design a large majority of JDK-related bugs were migrated into a single "JDK" project. In the end, over 450 legacy subcategories were simplified into about 120 subcomponents in JIRA. The 120 subcomponents are distributed among 17 components. A rule of thumb used was that a subcategory had to have at least 50 bugs in it for it to be retained. Below is a listing the component / subcomponent classification of the JDK JIRA project along with some notes and guidance on which OpenJDK email addresses cover different areas. Eventually, a separate incidents project to host new issues filed at bugs.sun.com will use a slightly simplified version of this scheme. The preponderance of bugs and subcomponents for the JDK are in library-related areas, with components named foo-libs and subcomponents primarily named after packages. While there was an overall condensation of subcomponents in the migration, in some cases long-standing informal divisions in core libraries based on naming conventions in the description were promoted to formal subcomponents. For example, hundreds of bugs in the java.util subcomponent whose descriptions started with "(coll)" were moved into java.util:collections. Likewise, java.lang bugs starting with "(reflect)" and "(proxy)" were moved into java.lang:reflect. client-libs (Predominantly discussed on 2d-dev and awt-dev and swing-dev.) 2d demo java.awt java.awt:i18n java.beans (See beans-dev.) javax.accessibility javax.imageio javax.sound (See sound-dev.) javax.swing core-libs (See core-libs-dev.) java.io java.io:serialization java.lang java.lang.invoke java.lang:class_loading java.lang:reflect java.math java.net java.nio (Discussed on nio-dev.) java.nio.charsets java.rmi java.sql java.sql:bridge java.text java.util java.util.concurrent java.util.jar java.util.logging java.util.regex java.util:collections java.util:i18n javax.annotation.processing javax.lang.model javax.naming (JNDI) javax.script javax.script:javascript javax.sql org.openjdk.jigsaw (See jigsaw-dev.) security-libs (See security-dev.) java.security javax.crypto (JCE: includes SunJCE/MSCAPI/UCRYPTO/ECC) javax.crypto:pkcs11 (JCE: PKCS11 only) javax.net.ssl (JSSE, includes javax.security.cert) javax.security javax.smartcardio javax.xml.crypto org.ietf.jgss org.ietf.jgss:krb5 other-libs corba corba:idl corba:orb corba:rmi-iiop javadb other (When no other subcomponent is more appropriate; use judiciously.)

Since these areas generally have dedicated teams working on them, it is easier to find bugs of interest if these bugs are grouped first by their cross-cutting component rather than by the affected technology. docs doclet guides hotspot release_notes tools tutorial embedded build hotspot libraries globalization locale-data translation performance hotspot libraries The list of subcomponents will no doubt grow over time, but my inclination is to resist that growth since the addition of each subcomponent makes the system as a whole more complicated and harder to use. When the system gets closer to being externalized, I plan to post more blog entries describing recommended use of various custom fields in the JDK project.

Just before JavaOne 2012, it was announced that the Duke's Choice Award program is being expanded to include the Latin America; Europe / Africa / Middle East; and Asia regional JavaOne conferences. The first regional Duke's Choice Awards will be held at JavaOne Latin America. The nominations deadline is Wednsday, November 7. The nominations page notes: The goal of the regional awards is to celebrate Java innovation happening within specific regions and provides an opportunity to recognize winners locally. The Duke's Choice Award program is open to all members of the respective regional Java communities and nominations are accepted by anyone, including Oracle employees, for any compelling use of Java technology. The regional programs will include Java community judges from the region. In keeping with the 10 year tradition of the Duke's Choice Award program, the most important ingredient is innovation. Let's recognize and celebrate the innovation that Java delivers within specific geographic regions. The winners will be announced at JavaOne Latin America, in Sao Paulo, Brazil, December 4-6.

Essential Studio for WinRT recently released by Syncfusion includes 20 enterprise class controls for building Windows Store applications. The controls are optimized for touch and includes several features. By Anand Narayanaswamy

Eclipse Orion, the new browser-based IDE for web development, has pushed out the final version of its 1.0 release, following 18 months of development. In a hands-on preview with 1.0 RC1, we found Orion to be an impressive and feature-rich effort, albeit one with a few strange design choices. That said, it’s come a long way since June’s 0.5 release, adding a whole host of minor improvements, including new code editor features, additional git support, integration of Eclipse Color Themes and Mozilla Persona login. Mike Milinkovich, Executive Director of the Eclipse Foundation, took to his blog to offer the project a brief congratulations on the release. In a blog post, Project Lead Ken Walker celebrated the progress made so far by the Orion project, both in the development of the application and uptake of components by the likes in Mozilla and SpringSource in Firefox and Scripted - as well as forming the entire basis of a platform in Cloudfier. The project is, of course, not just OrionHub.org, but an entire package that can be deployed (and modified) yourself. Walker also took a moment to reiterate Orion’s key feature, its plug-ins. “At the heart of Orion is a client side plug-in and micro service framework and this allows secure extensibility from multiple sites completely in the browser,” he wrote, adding: “This seems to get missed when reviews are done comparing Orion to other web based development tools.” The plan is to switch to a browser-style rapid release cycle, with a dot release every four months (version 2.0 is due next February). Planned improvements include an optional JavaScript backend to run in Node.js, further deployment solutions and offline support. You can try out the latest release at OrionHub.org (note that existing user accounts have been deleted), or download the source code from GitHub.

Hello, my name is Brian O'Neill, and I've been J2EE free for almost 8 years now. A long time ago in a blog post far away, I asked the question "Is J2EE dead?". Almost five years later, I'm here to say that, "Yes, J2EE is dead". In fact, I'd say that it is now generations removed from the emerging technologies, and an ancestor to current enterprise best...

The essence of creating a pipeline is breaking up a single build process in smaller steps, each having its own responsibility. In this way faster and more specific feedback can be returned. Lets define a true pipeline as being a pipeline that is strictly associated with a single revision within a version control system. This makes sense as ideally we want the build server to return full and...
