It will have been necessary to wait about 6 months to be able to appreciate the new version of SmartGWT, the WRAPPER GWT of SmartClient by Sanjiv Jivan (exit of version 1.0 during a previous review of the papers), information relieved by l and by The Server Side.
This version 1.1 brings many novelties (exhaustive list on the release notes):
An open source free bookshop in her entirety (licence LGPL), this does not deny itself or at least this tests!
Good news for the developers Flex, we learn by InsideRIA that FlexUnit 4 will be able to be used on-FlexBuilder 4-FlashBuilder 4.
In this article, the author introduces us new functionality that offers FlexUnit 4 such as:
The next supporting stage is to include plan into FlashBuilder 4. It is besides possible to vote for this plan. If it interests you do not hesitate to vote I too.
In keeping with the planning announced from last December during Devoxx, a new version of JAVAFX has just been available. Contributions are numerous and fill up some lack of version 1.1. The site of JAVAFX offers one tower of very complete horizon of novelties and Stephen Chin introduces a summary accompanied with a guide of migration. They will keep:
ListView the only component of high level is to be given, no table, nor with tree.VBox and HBox already available.Compatibility of binary generating by JAVAFX is not assured between this new version 1.2 and its precursors. It will be therefore necessary to re-compile applications to assure migration.
New JAVAFX will therefore have gone out in time to be the subject of many presentations and announcements during JavaOne who starts just today in San Fransisco. As we spoke to you about it some weeks ago, the support of TV could make the object of a demonstration there.
Is oracle going to return paid Popular dance? This question which all asked after the announcement of the redemption of Sun returns to the foreground with a sibylline sentence of the announcement of update version 6 14 of JVM of Sun today:
Although G1 simple percentage available for employs in this release, note production that employ of G1 simple percentage only permitted where has Popular dance support contract has been purchased
In theory, concerned functionality is still experimental and the redemption of Sun by Oracle is not closed: Oracle has not to interfere in management in the daily of Sun; he would not therefore be right there that Sun changes strategy on JVM.
However, such contractual limitations on JVM of Sun have been never seen. If JVM mobile and real time was always paid at the place of Sun as IBM and ORACLE GAPED/, JVMs server and workstation was traditionally free in one details near: JVM JROCKIT of BEA had become paid from redemption by Oracle; they had then invoked contractual considerations which prevented Oracle from distributing JVM free.
It is very spread JVM today of Sun that is threatened; one more time following a redemption by Oracle. Is it necessary to fear the end of free JVM? For the workstation, it parried very unlikely error of credible economic model but for servers, oracle's turnaround seems possible and in the descendants of the new policy of JROCKIT. There would remain then available free JVM IBM J9 and open JDK, the Open Source plan the gouvernance of which by Sun was subject to debate these last months. We will note in passage that G1 will be included in the version 7 open JDK.
To return on the novelties from update JVM 6 14, we will keep: the compression of the gun-layers (-XX:+UseCompressedOops) for JVM 64 bits (cf. Popular dance 64 bits, not so often a good idea), the optimisation of accesses to variables used on the only one thread ( -XX:+DoEscapeAnalysis ) and this Garbage First (G1) Garbage Collector) optimised for the management of big volumes of memory but reserved in production for the subscribers of a contract of support.
As all containers Servlet / JSP of the market, Jetty gets ready for the arrival of JSR-315 (Servlet 3.0) envisaged for this summer. Moreover, he operates on also various changes d s in his recent integration in Eclipse foundation.
Greg Wilkins introduced a detailed roadmap of the functionality which will be present in future versions of Jetty.
Jetty 6 remains stable version by waiting for the arrival of her successor.
Jetty 7 is the branch of development which Greg Wilkins recommends to adopt for plans starting currently. She will mark migration towards the package org.eclipse.jetty, and will bring a remodularisation accompanied with a packaging in bundle OSGI in supplement of artefacts Maven, and a preparation to Servlet 3.0 whose preview he will offer.
Jetty 8 will differ hardly from his precursor, it will be first of all about a rebuild in Popular dance 1.6 exclusively, be accompanied with a strict conformance to Servlet 3.0 whose specification will then be finalised.
No definite date is pointed out by the author, but it seems that the revision of specification Servlet 3.0 will constitute the main regulator of the calendar of Jetty.
Tellerium is an user framework of unit tests of interface. Plan leans on Selenium, is compatible with JUNIT and TestNG and allows to write tests in Popular dance, GROOVY or by DSL.
New functionality between version 0.5.0 and this 0.6.0 are rather numerous, they will note so:
Several new functionality therefore but especially many optimisations of performances, quicker and easier tests to be written, the whole using the most recent versions of plans on which he depends. To note the plugin also for FireFox TrUMP (Tellerium UI Model Plugin) allowing to write tests faster (recording of clicks, validation and customisation, export Groovy).

was held last week in San Fransisco. It is about one of the conferences intended for the user developers of applications and of IPA - INTERNATIONAL PHONETIC ALPHABET of GOOGLE. The actuality around this conference being relatively important, we decided to treat this one in a separated article.
In here is the main lines of what was seen in GOOGLE I/O:
To know more about it, you can read our ticket devoted to subject.
On Wednesday, June 3rd, 2009 at 16 h, Adobe offers a presentation of Flash Catalyst. This tool intended for the designers allows to conceive rich graphic components without programming. These creations can then be given to a developer Flex so that this last takes responsibility for clever programming.
This presentation is going to become divided into two sessions under forms of conferences and of workshops:
It ended with a cocktail at 19 h 30.

Good morning,
For G1, mention seems to have disappeared for qqc of more modified:
G1 simple percentage available ace early access in this release, please try it and give us feedback. Usage in production settings without has Popular dance for Business support contract simple percentage not recommended.
They (provisionally) saw again their copy by waiting for a more official act?
Concerning G1 and free JVM:
in priori JVM J9 of IBM for Windows is not available free for him everybody. For a long time she was only packag e with products IBM. Now downloading is free but it is possible to read the following thing on their site:
this simple percentage the IBM 32 - bit Runtime Environment for Popular dance 2 (JRE), Windows Edition. To be able To instal this JRE your computer must be year IBM SYSTEM, ace shown by has BIOS CHECK. it must also be running Windows Microsoft Miss, on 2000, and XP
And ' Must ' is in bold on the page IBM.
For G1, I think that everybody gets carried away a bit knowing that, as you say it, code is would be included in OpenJDK.
@ Alexis,
Thank you for this information. The unwarranted nature of JVM HOTSPOT is a sensitive subject.
Could you light us on order of size of the price of a contract of support JVM for, for example, to use HotSpot+Tomcat in production?
@Bruno,
A contractual limitation was often invoked to explain the absence of free downloading of JVM IBM J9 for Windows while it is possible for Linux. The same contractual limitation had been moved forward when the free downloading of JROCKIT had disappeared in the wake of redemption by Oracle.
As soon as the redemption of Sun by Oracle will be real, the possible contractual limitations to which is subjected JROCKIT will be able to be raised. Oracle could then decide to allow again the free downloading of JROCKIT.
On the bottom, is there sense to make paid JVM server at a time of the free BONES (Linux and open Solaris) and servers Popular dance free (Tomcat, JBOSS, Glassfish or Geronimo)? Sun, IBM GAPED and thought that not; oracle will be able to decide to change deal.

Good morning Cyrille,
G1 it is not complete, fair JVM GC that nobody still uses. If he had to be paying return it is not as though all JVM became paid and ca some options (non-essential but in added value) parried me very close to the model of mysql and Glassfish or are paid.
To answer your question (and I do not know why prices are not publicly shown), Popular dance for Business (support Popular dance in firm: updates manual, extended support, hotline) is a subscription indexed to the number of employees and it returns about to a coffee a day by employee during month
A to note that the support of JVM is not new, it was always a source of incomes for Sun (even if it is not rare that JVM on Windows still remains the only brick not supported by a workstation).
Finally, Sun remains even supporting an independent society and nothing of what is made and announced cannot be influenced by Oracle (in the worst it is ardour to Sun). Rules are rather strict from this point of view.
