RSF ("Reasonable Server Faces")
2007-09-21 10:29:00
RSF version 0.7.2 has been released. RSF promotes minimal and clean designs - in contrast to the majority of current Java frameworks which proliferate with increasingly complex schemes for managing stateful components, RSF cuts through the issue by promoting and facilitating zero server state designs. This brings web development more in line with the web - as well as making fewer demands on server resources, it arguably delivers apps which users find more idiomatic and intuitive.Other features since RSF's previous announcement at 0.6.1 include UVB (the "Universal View Bus") - a slimline DWR-like RESTful web service automatically derived from your webapp structure, and extensions to its rendering model allowing any section of markup to become a candidate for reuse.Going forwards, RSF is rapidly tracking the developments towards Spring Web Flow's 2.0 release, with its integration up to the mark for compatibility with the latest milestones of SWF 2.0M1 and Spring 2.1M3. RSF's focus ...

Google Web Toolkit out of beta as of 1.4 release
2007-09-02 18:32:00
There's lots and lots of cool new stuff in GWT 1.4, so it's hard to know where to start.How about application performance?! This release includes several breakthroughs that make your compiled GWT code significantly smaller and faster. Many users are reporting that after a simple recompile with 1.4, their applications are up to 30% smaller and 20%-50% faster. And startup time in particular is now highly optimized thanks to a new bootstrapping technique and the availability of image bundles.To see the new hotness in action, try visiting the new-and-improved Mail sample a few times. It's darn fast the very first time you visit it, but subsequent visits are insanely fast. That's because, in addition to a fast initial startup, GWT code uses a clever caching technique to prevent applications from making unnecessary HTTP requests.As Joel Webber (Tech Lead of GWT Core Libraries) would say, "The fastest HTTP requests are those that do not, in fact, occur."

Seven habits of effective developers
2007-09-02 17:50:00
ZDNet Asia's interview with Sun staff engineer Lee Chuk Munn, who likens writing applications to writing books. The habits he cited include: understand the problem, use appropriate tools, strive for simplicity, and so forth."Programming is just an expression to a solution. A lot of it is about understanding and recognizing the problem and getting help. This [concept] is generic across all programming languages, it doesn't matter what you use--whether it's C+ or Java. The approach is still the same," he said."What irks me is developers today are churning out applications without any regard or love for it. That's my number one pet peeve. So, it's like they're doing it for the money which is good, if you're a project lead, but you need to put in some concern and care into what you're building and not just in shipping [the application]," he noted.

PageBus and the AJAX Challenge: TheServerSide Video Tech Brief
2007-08-23 11:03:00
PageBus and the AJAX Challenge : TheServerSide Tech BriefUploaded by ciuranaTIBCO's PageBus is an open-source Javascript messaging bus for integrating heterogenous AJAX elements in a web page through broadcasting and listening of events published to specific topic names. Messages can be dispatched from one AJAX component to another, or they can be bridged with messaging systems on the remote server. Rather than hard-wiring the AJAX components on a page to talk to one another, PageBus simplifies development by providing a simple publish-subscribe API. This helps modularize applications and promotes team development, unit testing, and better source repository management.PageBus is the main integration technology behind the AJAX Challenge, a web development contest with the goal of creating the largest mashup in history. Are you up to the challenge?Kevin Hakman is the director of developer evangelism for TIBCO General Interface, an award-winning rich Internet application framework. Ge...

First Part. Short Intro.First of all , I must say that probably you already know about problem with memory leaks in IE. And also we have a lot of pages on different sites where people were discussed the patterns of memory leaks in IE.Just try to google on memory leaks in IE, or something like that - and you'll see.Main part. The problem.But I want to share with you the solution to a problem with memory leaks in IE.I want to describe you a problem, If you'll made your own AJAX-enabled component with a lot of javascript on the client-side, you may get the situation when memory allocated by IE will grow after each(or may be not each) component refresh with AJAX or whole page refresh probably.You could see such behavior , if you assign( by javascript ) to your AJAX enabled component any custom(means non-standard :) ) events or some specific functions, in which you'll get reference to that component.This is very popular way to do such things.And if you'll take your AJAX enabled compo...

QuipuKit 1.2 Is Available Now!
2007-07-29 17:35:00
QuipuKit is a JSF components library. I wrote about it in my past posts.I've tried it in two of my projects. Web applications that was made - working under Tomcat server, so I wasn't boring about Quipukit's compatibility with other servers. Now as was written in press release , QuipuKit library works under Jboss server, WebShpere server and support JBoss Seam framework.Other features are pretty good. Mainly I was using it's TreeTable and DataTable components.In version 1.2 Quipukit library now has SuggestionField component.As I saw in it's demo - it's kind an AutoComplete component.You can take a look by your own on the demo of QuipuKit library.$450 for per developer license - it's great price for library like that.

Aspect Orientation for Mashups using OpenESB by Gopalan Suresh Raj
2007-07-14 14:00:00
Modularity and Encapsulation have always been cornerstones of good software engineering. Modularizing concerns is an important way to ensure that there is very little overlap in functionality between software services. Concerns that defy encapsulation are termed Cross-cutting concerns. Cross-cutting concerns make a clear separation of concerns difficult to achieve since they may cut across many modules within a software application. Some examples of such cross-cutting concerns are logging which cross-cuts all logged classes and operations, or caching which cross-cuts all cached objects, or alerting, or message tracking, or auto-reconnect, or queuing, et aliae.Aspects help to encapsulate cross-cutting expressions in one place. By applying an Advice, at various points in an application called Join-Points, Aspects can alter the behavior of the non-aspect parts of a software application.The Java Business Integration (JBI) specification, JSR-208, provides a loosely coupled integration mo...

Java EE 6, OSGi & Sun on different wavelength's
2007-07-13 13:42:00
Java EE 6 is on the drawing board, but the opinions are already starting to diverge. Rod Johnson -- of Spring fame -- thinks Java EE 6 is on the right track, see the discussion on Rod Johnson: "Java EE 6 Gets it Right" . However, this is not the same tone adopted by some OSGi proponents. Peter Kriens over at OSGi writes: "Can someone tell Sun about OSGi", going onto say : Someone just sent me a mail linking JSR 316. A JSR that will specify Java Enterprise Edition 6, the successor of Java EE 5, which was defined in JSR 244.Now before we take a look, lets just investigate some recent trends in the Enterprise computing world. Hmm, BEA moved their micro Service Architecture on top of OSGi, IBM Websphere 6.1 seems to have chosen OSGi, Jonas is an EE framework build on OSGi from day one, and the JBoss Microcontainer is modified to support OSGi. On top of that, we have one product that made many people re-think Java EE: Spring. Now this product fell in love with OSGi. The market clearly s...

Seam and Flex by Shashank Tiwari
2007-07-11 11:08:00
JBoss Seam and Adobe Flex are two promising technologies. Seam makes it easy to build stateful web applications. It integrates the Java EE frameworks together. Flex is a great rich application development framework. The question is can they and should they be used together?Seam till its 1.x versions used JSF as the main UI framework. This implied that it was built around a server side UI model. Flex on the contrary is a client side UI framework. Oops! so we have a big disconnect right away! Not really, there possibly are some viable options to make them work together. In the latest version of Seam 2.0.0 BETA the coupling with JSF has been loosened. Also, in the past its been demonstrated that JavaScript UIs (built on frameworks like DOJO or any other) could directly remote to Seam server side components. Remember though that JavaScript runs within the browser whereas Flex applications runs within the Flash VM. Does that matter?One option is to have Flex as the front end and make Fle...

I think most of web developers on java, know that JSR 314is in the review ballot phase.This JSR is all about JavaServerFaces 2.0By next year when the specification is ready for release we would see a lot of goodies in JSF, some of them being -- better view decription technology - somewhat like facelets or maybe better.- application modification and deployment at runtime- tighter integration with Ajax. perhaps support for a small JavaScript library contract specification.- better and maybe centralized error handling- minimization of ?xml hell?, use of annotations instead- possibility of RESTful urls and use of GETs- skinning and themeing- reduction of effort required for creating custom componentsYou can view the requirements scratchpad for this JSR.

Remind about OSGi.
2007-07-08 14:08:00
OSGi is a specification of a Java based service platform targeted for use by systems that require long running times, dynamic updates, and minimal disruptions to the running environment.. The Eclipse Equinox project provides one of many available implementations of this specification (EclipseZone recently featured a podcast with Equinox project lead Jeff MacAffer) and serves as the reference implementation of the latest OSGi R4 specification. Initially, OSGi was targeted at home automation and residential gateway devices. More recently, it has found use in everything from mobile phones to cars. The OSGi specification breaks software up into units of functionality called bundles. As a result this makes OSGi an idea base for applications such as IDE and application servers that often have numerous "modules" that may or may not need to be started at runtime or after the application has been started. The Eclipse IDE has made use of OSGi as its base since version 3.0. More recently ...

Rethinking JSF - The Real Problem. By Joseph Ottinger
2007-07-07 15:55:00
This article is worth to look at. The main problem that discussed there is that JSF, for a component framework, has so few components.It is hard to disagree with that."So... where are the login box components? Where are the search box components? Where are the data input components? Where's the ability to manage "pretty URLs?" ("Pretty URLs" are also known as bookmarkable URLs, or search-engine-friendly URLs.) Where is the data flow? Where's the conversational state?There's absolutely nothing in JSF that prevents these things from being made, and some groups (vendors, open source groups) have already made some of them - frameworks and implementations like Seam, IceFaces, RichFaces, Tomahawk, NetAdvantage, and others. For others, code is readily available in books like "JSF: The Complete Reference" (Schalk, Burns), "JSF In Action" (Mann), and "Core JSF" (Geary). Some elements are even available on the web (for example, how to manage pretty URLs). There are also sites with lots of ...

JSR-275 - Units and Measures for Java 7 - draft terminates soon
2007-07-06 09:57:00
I really interested in what it would be? And how it would be implemented?This is what they say:"Java developers who work with physical quantities (such as developers in the scientific, engineering, medical, and manufacturing domains) need to be able to handle measurements of these quantities in their programs. Inadequate models of physical measurements can lead to significant programmaticerrors. In particular, the practice of modeling a measure as a simple number with no regard to the units it represents creates fragile code. Another developer or another part of the code may misinterpret the number as representing a different unit of measurement. For example, it may be unclear whether a person's weight is expressed in pounds, kilograms, or stones.Developers must either use inadequate models of measurements, or must create their own solutions. A common solution can be safer and can save development time for domain-specific work. This JSR proposes to establish safe and useful methods...
