Every company should plan regular architecture capability maturity assessments using a model. These should provide a framework that represents the key components of a productive enterprise architecture process. A model provides an evolutionary way to improve the overall process that starts out in an ad hoc state, transforms into an immature process, and then finally becomes a well-defined, disciplined, managed and mature process. The goal is to enhance the overall odds for success of the enterprise architecture by identifying weak areas and providing a defined path towards improvement. As the architecture matures, it should increase the benefits it offers the organization.
Architecture maturity assessments help to determine how companies can maximise competitive advantage, identify ways of cutting costs, improve quality of services and reduce time to market. These assessments are undertaken as part of the Enterprise Architecture management. java.sys-con.com |

Dr. www.topix.net | 2/3/12 9:04 PM Planet Eclipse: Doug Schaefer: Eclipse C/C++ IDE reaches 750,000 downloads for Indigo-SR1
 Planet Eclipse: Max Rydahl Andersen: m2e(clipse)-wtp 0.15.0 : New & Noteworthy
Maven Integration for Eclipse WTP 0.15.0, a.k.a m2eclipse-wtp, a.k.a m2e-wtp is available. This release contains mostly bug fixes, but a few improvements managed to slip in. The complete release notes are available here.
m2e-wtp 0.15.0 is compatible with the JavaEE distributions of Eclipse Helios and Indigo, requires at least m2e 1.0 (works with 1.1) and mavenarchiver plugin >= 0.14.0 (0.15.0 should be automatically installed). As usual, m2e-wtp can be installed from :
So let's see what are the highlights of this new release : Packaging inclusion/exclusion support improvements For war project, previous m2e-wtp versions used to use and attributes from the maven-war-plugin config to enable (or not) the deployment of project dependencies to WTP servers. In 0.15.0, the same level of support has been added to EAR projects using maven-ear-plugin 2.7+. However, the problem with this approach is, other resources (web pages, classes ...) are not properly excluded (using the <*SourceInclude> and <*SourceExclude> attributes).
In order to address this problem, Rob Stryker, committer on WTP and lead of JBoss AS tooling in JBoss Tools, provided an implementation for JBoss AS servers that might be generalized to other WTP server adapters (if they decide to do so). Basically, some new metadata is added to the project's .settings/org.eclipse.wst.common.component like : ...
The patterns are separated with a comma and exclusions take precedence over inclusions : resources matching one of the exclusion patterns are not deployed, even if they match one of the inclusion patterns. That solution is not maven-bound so any other kind of project can benefit from it. Now all m2e-wtp 0.15.0 does is map the maven patterns to their equivalent component metadata. This gives :
In the example above, a warning is displayed as both and are defined. Since both patterns could overlap, it might lead to some weird behavior where WTP would actually deploy more files than a maven CLI build. In order to minimize (we can not totally solve) that potential discrepancy we only keep the packaging patterns in the component files and recommend using only.
Currently, this feature only works in combination with the JBoss AS Tools from JBoss Tools 3.3.0.Beta1 (nightly builds available from http://download.jboss.org/jbosstools/updates/nightly/trunk/), but we'll try to make other WTP Server adapter vendors support it in the future (as part of WTP core API). Warnings added when unsupported dependency types are detected As of today, if a project depends on another workspace project of type ejb-client or test-jar, that specific dependency will not be packaged properly by WTP, as Maven would do in command line. Moreover, you'll experience some class leakage on the compilation and test classpaths in Eclipse (ex: non client classes being visible). The only known workarounds to this issue are to disable workspace resolution, or close the dependent project and rely on the dependencies from the local maven repository. Ideally, in order to make the deployment part work, we would need to introduce new WTP components, but the current WTP API doesn't support it, yet. So, until this is fixed, warning markers are added whenever a project depends on such "unsupported" types. That should hopefully give users an idea of the problem and how to circumvent it.
Previous m2e-wtp versions had, in some use cases, some outstanding issues with regard to dependency management of war projects. In particular,
org.apache.maven.plugins maven-war-plugin 2.2 @{artifactId}@-@{version}@@{dashClassifier?}@.@{extension}@ Removal of conflicting facets on packaging change If you had a java utility project, that you wanted to upgrade to an EJB project for example, a constraint violation would be raised upon project configuration update (EJB and Utility facets can't be both installed). This has been fixed by removing all conflicting facets when you change the packaging of a Java EE project, making that conversion completely transparent. What's next? m2e 1.1 introduces a new Eclipse to Maven project conversion API. It means that, in m2e-wtp.next, we will be able to automatically convert existing WTP project configuration to maven's. Dependencies will still need to be set/translated manually but that's a pretty good start IMHO. Finally ... I would like to thank the m2e-wtp community at large for their support and contributions, that's what make this project move forward and make it one of the most popular projects on the eclipse marketplace. Contributions can take the form of :
Keep it up.

I am very pleased to announce the release of SwingX 1.6.3. While the release notes contain many fixes, I wanted to take a minute to highlight some of the major changes. First and foremost, we have more fully adopted Maven. The project is now a collection of smaller modules. This will make it easier for clients to use only the pieces of SwingX that they need or want. To enable us to break SwingX into smaller modules, some classes have been moved or reorganized. Don't worry, we've left a deprecated copy in the original location in all instance but one (I'm looking at you JXBusyLabel.Direction). Secondly for Maven, we needed to rename our groupId. Per discussions with the maven.java.net folks, we are now using org.swinglabs.swingx as the groupId. This is a change from org.swinglabs. Doing so allows us to use the maven.java.net facitilities for automatically updating Maven Central with our releases. Future releases should be a lot easier for us in that regard. The third Maven-related change is that swingx-core no longer contains a copy or dependency on all SwingX classes. The swingx-graphics package is not used by any of our components. To suppliment the need to have an all-in-one jar, we have created the swingx-all module which provides all SwingX content as a single JAR file. To highlight some non-Maven changes, we have:

Hi, Do you need to monitor your Mobile App?
Mobile applications are more and more becoming part of a company’s online services. This leads to the question whether we need to monitor like other parts of our IT infrastructure. As they are part of our shipped application services we need to ensure they are working properly. However, not every application must be monitored the same way. Additionally monitoring always comes at a certain cost. We need people to take care of the monitoring, we have to prepare our applications to be ready for monitoring and we potentially also have to buy or at least integrate new monitoring tools. So is it worth the investment? Planet Eclipse: Roy Ganor: How My Wife Drives the Technology World
ok, maybe a better name would be "Cloud -based Social -enabled Service -oriented Mobile -apps development", but that's a long and exhausting name especially for my "Thursday blogging day" :) It started last week as a small-talk between my wife and me about sheattending so many shifts and medical sessions. According to my wife, she usuallytakes 4-5 shifts a month where the actual number is doubled (!). At that momentI had no tools to prove my point and here comes the requirements to build asmall mobile app for her to report shifts and sessions while being able towrite short notes about it (ok, she was asking this a longtime ago). In addition she usually posts some info on Facebook during her shifts so I had to connectthese reports somehow to her Facebook account. By the end of the month she hand a report about her shifts to the managers so this if the app could also print a summary it will be a big value for her. Before I share some thoughts about some aspects of this app development, here is how this app looks like on Android and iOS:   Mobile App jQueryMobile (version 1.0) is really handy for creating cross-platform mobile interface, it provides easy to use APIs and is really covered well with lots of great examples . I had to use several other libraries like jQueryUrl , Moment.js , Mustache , requireJS and jsPDF . With so many "out-of-the-box" libraries it is super easy to build robust solution on for client side in minutes(!!!) Social-enabled : Facebook JavaScript SDK helped me with giving a more "social look and feel" after creating a Facebook application . I also used Facebook's OAth service authentication and Open Graph integration so users notify their friends about their activities with the "My Doctor Shifts" application. Service-oriented (and Data-centric) Zend Framework provides nice (lightweight) models representation and the MVC was useful to create the HTML view and services. Cloud-based Using phpCloud was easy as always with plenty of slick workflows helping me to easily deploy my application and push updates to staging and testing targets. This way I always kept two versions that represent my Work in Progress and Done apps. I also got packages ready for deployed in case I want to deploy it to another Zend Application Fabric instance. The application is available on github .  Planet Eclipse: Jordi Böhme López: Accessing a very large data set with mobile devices
A few months ago my colleague, Ralf Sternberg, wrote an article on “how to access a huge dataset with the web browser“. Now, if it’s possible to access very large datasets with a browser, wouldn’t it be really cool to access it in the same way with mobile devices? As you may have heard, we launched RAP mobile two days ago. And, we did just that. With RAP mobile you can access exactly the same dataset with exactly the same code as in Ralf’s post. The dataset contains over 500,000 emails totalling over 2GB of space. Check out the screencast below and the source code on github. What I find intriguing about this framework is that it is fast. There is no data on the phone. The information displayed in the UI is retrieved asynchroniously from the server while the user is scrolling through this enormous set of data. The native iOS client takes care of the proper preloading, caching and memory management. eclipsesource.com | 2/2/12 8:58 AM 5 hot specialties for software developers

As part of Virgil's ability to deploy ruby scripts to a remote Hadoop cluster, we needed to package gems' into that Hadoop jar. After a bit of monkeying around, we got it. This is the key piece of information: "Because the operation of Java's classpath and Ruby's load path are so similar, especially under JRuby, they are unified in JRuby 1.1. This results in a number of unified capabilities:...
First thing you need is to actually get your hands on the gem. To do this, you can run jruby to grab the gem.
java -jar jruby-complete-1.6.0.jar -S gem install -i rest-client rest-client --no-rdoc --no-ri
This will fetch the gems and install them into the current directory under the directory "rest-client". In that subdirectory you'll find: bin, cache, doc, gems and specifications. The actual code for the gems is found in the gems directory. In the case of rest-client, you'll find two directories that contain the code: mime-types-1.17.2 and rest-client-1.6.7.
This is what you need to bundle into the jar. We copied those two directories into our java project under src/main/resources/gems/.
One approach would be to simply include those directories on your classpath. Another approach is to programmatically adjust the loadpath to include those directories. You can do this with the following lines:
List paths = new ArrayList(); paths.add("gems/rest-client-1.6.7/lib/"); paths.add("gems/mime-types-1.17.2/lib/"); this.rubyContainer = new ScriptingContainer(LocalContextScope.CONCURRENT); this.rubyContainer.setLoadPaths(paths);
Then, when using this.rubyContainer you'll be able to run ruby files that require the rest-client.
Since the ruby scripts are actually loaded via the classpath (from the loadpath), jruby is happy loading them from within a jar. In our case, we built the jar using maven and the gems were included in the jar because we put them under src/main/resources/gems.

In current post I am going to explain how to use Hibernate Query Cache to avoid amount of traffic between your application and database. |
