I cannot find time to post any interesting things lately, so I can only share great stuff with readers.
This week end, Laurent Bois has published a great post about:
- Deploying a remote (OpenSocial) Google Gadget made with GWT in eXo
Take a look to this tutorial, that is based on eXo Portal 2.5 and eXo WebOS 1.5.
Thanks Laurent for this great post!

When working on software design, UI Mockups are quite important and Patrice, colleague of mine at eXo has pointed me to a very cool tool to use when you have to quickly do a mockup, and work with the dev team in an iterative fashion: This tool is "Balsamiq Mockup". Here an example of mockup realized with Balsamiq: Also if you read more about the tool, you can see that it has native integration with others tools such as JIRA, so cool to be able to integrate a mockup easily when defining a new item... Take a look to this screencast explaining the basic features and use of the product:
Another interesting tool is the online white board "DabbleBoard" that allows user to quickly create and share graphs, ideas, ... A very cool feature of this tool is the automatic recognition of shapes. The best way to understand, is simply to see it in action:

I have been within eXo Platform for almost 2 months now.. As expected, it is crazy, and exciting. This is why I did not have lot of time to blog... Ideas are here, just time is not... So here a very quick post on my current work... We have been releasing new releases of products (Portal/Portlet Container, Collaboration Suite), deliver a training on eXo Portal, writing docs, articles, and many other exciting things... One of them is this nice example of integration of GWT Google Gadget in eXo WebOS. During this period, when I was not working with customers, prospects and partners, I have learned a lot about one of the most exciting and powerful features: eXo ECM coupled with eXo Portal/WebOS. eXo exposed using a powerful UI, and set of API, its JavaContent Repository on which you can build powerful sites/portal using eXo templating engine... and one other cool thing, at least for me, is the fact that most of the programming that you do, including rich Ajax based application is done using Groovy. (using GroovyServer Pages)... More to come about eXo features on this blog, but the best place to be is to follow our company/project blog at http://blog.exoplatform.org, where all the team is presenting new features, and events of the eXo community... Also, I have created, with Sebastien Roul a JUG in Nantes, here some information for French people:
Tuesday, June 17, 2008
I am very excited to say that this week is my first week as an employee of eXo Platorm. Excited for many reasons.... I'll pass on the excitement of a new job, we are all excited about that... So what are the others reasons:
- working for open source
- be part of a visionary team/product.
Working for open sourceSome of you know that I have been working for Oracle from 1999 to 2007, and lately for Sogeti (Cap Gemini Group) that is one of the biggest IBM's partner... So moving to eXo Platform an open source company is definitively a big shift for me. Anyway, I was looking for more “agile” working environment....
I am pleased to work for a product where users can follow on a daily basis what is the exact status of the different features, not from marketing slides but directly from the source trunk... But also where any user can influence the product either by providing direct feedback to the developers using mailing lists, tracking tools and wikis; even more if they want to participate to the development itself.
So being open source, will avoid some kind of lock-in, but this is not the only point: standards is another important point. eXo Platform, since its first release in 2003, has been great about defining, supporting and implementing standards. So eXo Portal is a great implementation of a JSR-168 portlet container, and it is today also one of the first portal and portlet container supporting the new JSR-286 Java Portlet API. In addition to the Java Portlet API support, it is also possible to consume remote portlet using WSRP 1&2. As you can see eXo Portal is a great solution to implement and integrate an enterprise portal based on standards. In addition to portal standard, eXo is also providing a powerful ECM that is based on a Java Content Repostory (JCR/JSR-170) implementation.
Based on the fact that eXo is open source and support industry standard it is a great tool to use; and it has been chosen by some other projects for example:
- NovaForge: an innovative Forge platform that aggregates and glue several Open Source tools used for Software Developments such as SVN repositories, Bug trackers, Continuous build… It used eXo WebOS and ECM to provide a single access points to all the resources as you can see in the following screenshot.
- Bonita: is an open source workflow and BPM that is using eXo WebOS to expose its console, as you can see in the following screenshot
You also have other softwares that are using various part of the product from te JCR to the Portlet Container... it depends a lot of your needs...
Working with visionary team and product
eXo Platform is a lot more than en enterprise portal. The core architecture of eXo is based on an internal SOA built at the top of an IoC container (Pico Container). This architecture has been leveraged in many point to expose new services and assemble all the components of the eXo Platform suite.
Let's take a quick look to the components of eXo Platform:
- eXo Portal 2.0: create and publish your portal using a simple and powerful Ajax based user interface
- eXo ECM 2.0: manage all your digital assets that are stored in the JCR, and expose them using many protocols (WebDac, FTP, CIFS, ...)
- eXo CS 1.0: collaborate inside and outside your enterprise using shared calendars, WebMail, Forums and Contact Management
- eXo WebOS 1.0: virtualize your desktop in this revolutionary user interface, where you can expose portlets and widgets and run any Web applications.
In addition to these component that are available today in the eXo Ultimate distribution or as stand alone solution, you can see in the source trunk:
- LiveRoom: a Web based real time collaborative tools allowing shared whiteboard, visioconference/VoIP using once again your browser, (in fact we have been implementing it using Flash/Flex)
- WCM: Web CMS System that is extending the ECM to facilitate Web site publishing.
- and many other features...
One last example of the vision of the eXo Platform is the fact that all services could be exposed either as REST Services using the JSR-311 (JAX-RS) or as SOAP Services using the JSR-181 (Annotations based services).
One of the feature that I am currently watching closely is the implementation and support of Open Social standard, that allows easy integration of "social-applications" with other very hot subjects for the “Enterprise 2.0” such as social networks, mashups and so on...
Stay tune, and take the time to download and install eXo Platform...
As a closure, I just invite you to take a look to eXo and contact me if you have any question about the product or if you have

We are all badly impacted with the price of oil. Yeah it really expensive,
now people is the US have a gas that is as expensive as France's
prices, shocking! ;).
Anyway, I do not want to talk about cars and gas, but really on the
good effect of the expensive oil. I do believe that expensive oil has
good impacts, not for my bank account but for the "planet", and may be
indirectly for software industry.
Change in transportationFirst of all, we are all forced to try to save gaz/enegy to save money. So people are thinking more about alternative to "individual car driving": carpooling, public transportations are more often used these days. I addition, people are using public bikes that you can find more and more in cities now. Nantes, where I live has launched its new program "Bicloo". So not only people are changing but I am sure industrials will also adapt to this offering greener alternative to oil for transportation. Personally, I would like to buy a cheap electric car to be able to go in the city, at least to reach the various Park&Ride points. I have to say that I really like the Google RecharcheIT initiative, that is used to charge plug-in hybrid cars... This is enough for the "transportation" and cars....
Change in way we do workI believe also that expensive oil will have an impact on the way we do work: we must try to avoid traveling all the time. Some work could be done just using the Internet and good collaborative tools. When most of a work is about: reading mail, phone talks, and meetings all these activities could be done using "IT" isn't?
I used to work from home a lot when I was working for Oracle HQ from France: the working kit is quite simple and not that expensive: laptop, fast Internet connection, VoIP phone, VPN and a Collaborative Suite (webmail, shared calendar, web conference tools, social networks, ...). Using this simple set of tools I was as productive as any employee but without traveling that much. I do not say that we should all work from home or smal local office, but we should try to do it. And limit our endless travels, that burns so much energy for CO2.... Yes all the IT is also consuming energy, but I do believe that it is probably easy to make IT industry "greener" than car industry... (I might be wrong...), but still at the office we will use computers/IT anyway..
So many of the software vendor are offering tools to make us more productive using the "network as the computer" -we all remember this-. One example of tools that in fact is "greener" is eXo Platform. eXo provides all the tools for collaborative work: personalized portal, webmail, chat, shared calendar, ... and soon LiveRoom that is the Web conference/VoIP solution integrated to your navigator (Flex based application). In addition to this, users can also virtualized their desktop using eXo WebOS, and access his work environment from everywhere... I know that other solutions are available on the market, from various vendors such as Oracle, IBM, Microsoft, I have chosen eXo first of all it is an open source project where any user can participate at least by asking from requirements proposing ideas, but also and mainly because its offering is based on industry standards that will help integration to any existing IT systems. (... and also because I am currently working closely with the eXo team...)
IT for a greener worldIn conlusion, we, IT folks can I have some impact on the environment by helping people to be more effective when doing remote work, avoiding useless commute... Clearly, the technologies are avaiable today to help us, to work efficiently from home or "virtual offices" the main constraints are coming from enterprise/management culture.

Like many of you I am following TechCrunch, and one of the latest post was quite "amazing":
- see the Twitter! post from Michael Arrigton.
I have to say that I am quite impressed by the large number of comments that have been made using Seesmic. Bravo to Loic Lemeur's vision for this tools... This is simply the new and easy way to really do the "read/write" Web, I should say "record/watch" Web.
One thing is still bothering me, how to I find interesting content that is saved using Seesmic? Yes, I can use social features to subscribe to people that are sharing similar center of interest. But I cannot find any folksonomy on Seesmic, am I missing it, or it is just not available yet? Or let's dream and imagine than Web search/index engine will be able to index these video content to help me to find interesting content -may be this exists but I have not found it yet-. Loic, is it your next big feature to transform Seesmic in the next killer app?
So far I do not have the feeling that I missed anything -watch the comments and you will understand-, but it looks like people love to use the video to discuss/share with others, and I can understand why... We have moved from technical tools: Complex Web Authoring Platform, to easy Blog publishing, to pure video recording tool, so very easy indeed. I can imagine my mother posting a comment to a blog or video now... thanks to Seesmic!

Lately, I have been presenting Web 2.0 tools to my coworkers, and explaining how it could be used to improve the way we do "things" (especially business). Here a list of some of the tools I am talking about blogs, wikis, second life, social networking/bookmarking/tagging/rating,, facebook, friendfeed, youtube, seesmic, feeddo, flock and many others depending of the questions and the mood of the moment...
One of the tool that I love to present is Twitter... and now I have an good example of why we all need to be on Twitter ;)
Control Lights with Twitter from Justin Wickett on Vimeo.
Thanks to Justin from Twitter...

Andres and Guillaume have posted on the Groovy Users list the pointers to many (if not all) the Groovy and Grails sessions of JavaOne 2008... You want to learn more, this is a great opportunity to do it so:
Thanks to all of the authors... I would love to be there watching these session live... This post is the opportunity also to point you to this video from InfoQ of Jason Rudolph doing a very nice introduction to Grails during last year QCon conference...

Yesterday, I have been surprised when I saw the following announcement:
- Sun Microsystems Joins Liferay Open Source Community / Sun's new Web platform to leverage core elements of Liferay Portal 5.0.
So today what does that means? Liferay is leveraging the development power of Sun to implements standards (for example JSR-286). I have always been frustrated by the lack of standard support and 'real' innovation in Liferay (compare to its competitors such as eXo Platform, and Jboss for example). In the other hand Sun will leverage the "tiny Liferay product" killing its own solution. Sun's portal is really to big without that benefits for developers/users (compare to its competitors, BEA,IBM, Oracle for example).
So what's the next step for this partnership? If Sun wants to push a real portal offering, it can only finish by a full acquisition of Liferay... even if it is stated that it is not the plan.
Let's wait and see how this "WebSynergy" goes... However one thing is cool, it will put more visibility on Enteprise Portals. With all the Web 2.0 stuff: social computing, mashups, collaborative works/intelligence, the need for "Enterprise Portal" (I should add a 2.0) is back stronger than before...

Last Friday (April 18th) I was attending the launch of "eXo WebOS" in Paris. Benjamin Mestrallet, creator of eXo has started the event with a presentation of the solution and its impact on the IT. Like any internet user, each time I see eXo Web OS and applications I am very very impressed. They have pushed very far the use of AJAX based applications to offer a complete virtualization of the OS/Desktop, not in a Virtual Machine, but simply in your favorite browser.
- M6. M6 is one of the major French TV channel. M6 is using eXo for their new intranet. Some of the key point that I kept from this experience:
- Flexibility/Agility of the platform: M6 IT has been able, with Business&Decision, to answer end user needs in term of design/look&feel. Quite important in media industry ;)
- Extensibility: in addition to the pure publishing of personalized pages, eXo has showed lot of power. Creation of new services based on the core architecture of eXo (IoC based container), or simply by creation new Groovy script to capture events in the Java Content Repository. One example of such script, is the creation of a new script to automatically resize images when they are published in the repository.
- Belgium Minister of Finances, with Bull Belgium In addition to the classical portal usage of eXo. They have chosen to put in place for their 30 000 users, the brand new eXo Collaboration Suite (Mail, Calendar, Contacts) and even more exciting use the real time collaboration tools provided by eXo LiveRoom. This extension to eXo provides using a Flex based architecture exciting tools for collaborative work:
- Video and Voice over IP for Web conferences
- Shared Whiteboard allowing multiple people to see and modify documents and graphics
- it shows how the "Web 2.0" can really facilitate the collaborative work
- eXo is a green product ;) because with the eXo CS people do not need to travel to meet and work together.

I am just cross posting this entry to react to this very interesting article:
- Exposing a Database as a Web Service a developer.com article...
Oracle Application Server Web ServicesIf you are an Oracle Application Server user, you may know that it is possible to expose database resources as Web Services using the OracleAS Web Services stack. You can for example using JAX-RPC based Web Service create service on a PL/SQL stored procedure, a SQL statement and even poste message on a queue (AQ). This is available in the Web Service Assembler (wsa) tool and also JDeveloper.
At the end when you have executed the wizard, you have a complete JavaEE application ready to be deloyed. All the JDBC calls and PL type mapping are done automatically by the wizard... very neat Take a look to the Assembling Database Web Services documentation.
Here the archtecture schema of OracleAS Database Web Services:
It is important to mention that such service can leverage the WS-* support of OracleAS and any JAX-RPC handler you want to add to the service.
BPEL PM and Database ResourcesIn addition to a pure Java developer approach it is also possible to expose database resource as Web Service using Oracle BPEL PM, yeah... it could be overloaded, but still it is possible and very easy to do. See the chapter BPEL: Communicating with a Database
Oracle RDBMS 11 NDWSOrale RDBMS introduced a new feature that is called: Native Oracle XML DB Web Services, that allows developer to directly expose Web Services from the DB. Take a look to the chapter Using Native Oracle XML DB Web Services.
Note that in this case you do not have any WS-* support without another technical solution that could be Oracle Web Service Manager or any other solutions (such as a SOA appliance like for example IBM dataPower)
hmm I have not used that much this feature since I have left Oracle... I wonder when Oracle will provide a OS X release that will allow me to use my computer without any VM...

Now that I am back in consulting business, I often have customers where I am not allowed to connect my Mac on the network. Annoying!!!! But this is not a big issue since now it is easy to bring you environment on a USB key.
XWikey: my wiki on a key
On a daily business, I have installed my personal XWiki on my 2Gb USB Key, and a JDK (for windows, on OSX I am using the default one). So with this solutions I have my personal CMS, Website and applications with me, and I can use it from any computer available. I work on any site, any meeting room directly on my Wiki even when I am not connected. I am using a packaged Entprise XWiki that comes with Jetty and HSQL, so it is a complete and self contained environment. I just changed the start and stop scripts to point to the JDK that is on the key. Nothing exceptional here, but it is very useful.
Others portable applications
I know that a Wiki is not enough most of the time to " bring your life with you", and you may want more, such as Open Office, Mail and Web clients, ... Some of the packages you can use:
- PortableApps take a look to the list of applications that are available in a portable fashion
The next test will be to run the OS from the key, I have not done it yet, have you? Some options for this:

You are looking for a Wiki... take a look to this very nice online tools:

By default Oracle Web Service client is sending the SOAP messages using an UTF-8 encoding. This is the recommendation of WS-I Basic Profile. To be exact it says UTF-8 or UTF-16.
It is quite simple to change this encoding...
First you have to know that the JAX-RPC container will return the same character encoding than the one that is received. To change the character encoding, you just need to set the ClientConstants.CHARACTER_SET_ENCODING to the value you want to use. Here some simple client code:
Stub stub = (Stub)myPort.getPort();
Most of the Web Services stacks are offering the same kind of utility to do that, for example here the property you must set to do the same in IBM's JAX-RPC implementation: com.ibm.wsspi.webservices.Constants.MESSAGE_CHARACTER_SET_ENCODING.

Last week, more than 400 people of Sogeti group were meeting at Les Fontaines, for the annual KickOff. It was for me the first big event since I have joined this company last October.
- Rolf Jensen : talking about the Dream Society, explaining that the next step for business is to add an emotional aspect into it, to add value... I am a emotional person, and I can tell that I am buying Rolf's idea, and like most of Apple fan you can tell how important are the emotions to do business...
- Rod Bekstrom, co-author of the well known book "The Starfish and The Spider" focusing on the fact an company must shift from a centralized organization to a decentralized one. You can listen to the presentation online on Rod's site.. I have to say that I soon as I have finished my current readings (RestFul Web Services-O'Reillys & Get Things Done) I will order this book. I really found some inspiration in Rod presentation, and his ideas could be immediately put in place in your organization or at your customer site.
- Last but not least, Nick Donofrio, EVP Technology and Innovation, talked about the important of innovation for the enterprise, and how we do not control the changes but we should adapt to it in a productive manner to stay at the top.

You have probably heard about IBM ProjectZero, this "incubator"project from IBM pushing a new way of building, assemble and run Web applications. I won't talk about the technology in this post, it will come later, but just comment about the way this project is developped: a Community-Driven Commercial Development process.
- the development team, mainly IBM folks, want feedback, insight, suggestions, and criticism from the community. So we as the community can really be involved in the product in a stage where it is usually inside IBM labs without any visibility for non IBM employee... This is quite exciting to see that we can really discuss with the development team as they do the product, and we can see the product evolving based on "real" customer requirements/comments.
- so as "future" user of the production release I can discuss the features. As a developer of the "current" development release I can participate to the future product.

I have just created a poll -see leftbar- asking to list the different tools you are using for business. In fact I would like to have some feedback of you use of Wiki, Blogs, Instant Messaging on you daily job.
- Internal and external communication with Wikis
- My blog that you are currently reading
- Chat, I use probably more the chat than phone these days (thanks to http://meebo.com when I cannot connect with a rich client)
- Social Networking: I am not necessarily talking about big sites like LinkedIn/Facebook but more internal sites. For example, back at Oracle we had access to an internal Social Network site, that is now exposed at http://mix.oracle.com, and now at Sogeti, in the Cap Gemini group we do also have internal social networks.

With the latest big news around Oracle-BEA and SUN-MySQL deals I have missed an interesting article on Infoq with the following title:
- Request: Sun, Drop Support for JRuby
I have to say that I do agree with Craig Wickesser asking Sun to Drop Support for JRuby.
I am not a RoR expert, far far away from it, but I have learned it, and developed small applications with it, and I have to say that I love this framework. And I am sure that like many Java developers that used RoR, I was thinking: "If only I had the same productivity in my favorite platform: J2EE...".

Disclaimer: you do probably already know all these sites if you are like me spending lot of time on the Internet... (too much time?) But still, some people could be interested, like the customer I have been working with lately...
During a presentation to a customer around Web 2.0 and Social Networking, which sites do I use myself and why they could be interested for customer and their business.... So I really quickly write up this list, and just want to share it here...
|Social networking... and many more. More and more important in business.|
|Multimedia site... I am sure you all use it daily. I have used this to share pics about events (internal or external).|
|Social links, content is rated by user.|
|http://www.basecamphq.com/||Project Management tools, you need to look to all the 37signals applications. Very useful|
|Google services are terrific, as user or developer.|
|http://wetpaint.com http://wikidot.com||Public and free wiki that I used to communicate with customers, coworker and friends.|
|News and content syndication.|
|I use these site as consumer, but these services are more and more important in customer business, and will be part of our job as developer/integrator.|
Hmm, when you see this list you can tell that I am a very happy Google user, and I have not talk about the other services that I use from Google: Gmail, GTalk, Analytics, Notebooks, and obviously the search...
