First European Nuxeo Developer Day - Dec. 1 2008

adminsf — 2008-10-05

I’m pleased to announce that we are organizing, with the help of several other people, the first “big event” in the Nuxeo Community: the Nuxeo Developer Day.

It will take place during the “Open World Forum” event in Paris, on Dec. 1 2008.

The program is still under construction, but in any case I can promise it will be intense and will please even the most hardcore developers.

Here are some highlights:

What’s new in Nuxeo 5.2 (codenamed “Chicago”)
Roadmap for 2009 and beyond
Interoperability (including the emerging CMIS standard)
Several case studies from all across Europe (Spain, Sweden, UK…)
Technical talks about just about everything that is new or cool in Nuxeo 5.2:
- The new Nuxeo Core / SQL repository
- OpenSocial integration
- WebEngine
- RIA frontends (Flex, GWT…)
- Glassfish integration
- Nuxeo Runtime and OSGi
- Nuxeo RCP
- Mobile applications w/ Nuxeo
- Semantic applications

All the talks will be given in English.

Attendance is free. Even lunch will be provided by the organizers ;)

However, as there are only a limited number of seats (50) in the room, we ask that you to register before the event (preferably ASAP).

You can do so by just sending me an email (sf@nuxeo.com).

Or by registering on Facebook if you have an account there (you may also want to join the Nuxeo User Group on Facebook).

Note that the Open World Forum lasts for 2 days (see the full program), so if you’re coming from far away, and are interested in the politics or economics of open source and innovation in Europe, you may also want to stay in Paris for the second day (Dec. 2).

First Release of Nuxeo WebEngine

adminsf — 2008-07-11

WebEngine is a lightweight, versatile, content-centric, open source web framework to quickly build and deliver next generation content-oriented web applications.

WebEngine relies on the Nuxeo content infrastructure (OSGi runtime, component architecture, document repository, ECM services, etc.) to provide a component-based programing model and a web development model for building componentized content-centric applications (such as wikis, blogs, content-oriented websites, etc.).

WebEngine relies heavily on the REST paradigm: URLs are mapped to the hierarchical content repository, content is accessed using GETs, user actions are GETs and POSTs, etc. Hence it’s very easy and straightforward to write RESTful apps using WebEngine.

WebEngine is fully extensible and componentized, thanks to OSGi (all components are OSGi bundles) and Nuxeo Runtime’s extension points.

WebEngine can run either standalone (with startup time <4s) using the Nuxeo Runtime launcher and the embedded Jetty 6, or in a full-blown Java EE app server such as JBoss. WebEngine can also be connected to any Nuxeo EP instance (and Nuxeo Core repository) and be used to expose / publish its content to the web.

Features highlights:

Scripting (Groovy, JavaScript, Ruby, Python…) or Java code for business logic
Advanced content model
Leverage Nuxeo Platform’s ECM services
Smart URLs management
Powerful templating (based on the FreeMarker engine)
Wikitext renderer (using Wikimodel)
Open source under the LGPL license

Google Web Toolkit integration in Nuxeo EP

atchertchian — 2008-07-03

The Nuxeo application extensively uses JSF facelets and Seam for its rendering:

Seam provides a great bridge between Nuxeo services and JSF rendering, using contextual components;
The themes and layouts modules rely on facelets to build rendering based on contributions to extension points;
The url module relies on JSF phase listener and navigation handler pluggable behaviours to provide bookmarkable urls to documents.

Even though last versions of Seam offer a very clean integration with Richfaces/ajax4jsf JSF libraries, the Google Web Toolkit (http://code.google.com/webtoolkit/) looks like a good alternative when dealing with the more complex screens.

For instance, rendering a table of documents with pagination, sorting and selection support is not straight-forward with JSF facelets.

While JSF goal to separate logic and rendering can be seen as too restrictive for a framework like Nuxeo EP, GWT makes it possible to keep this separation and not lose any expressivity because a GWT application is written in Java. Also, JSF has a quite steeper learning curve than GWT.

Integrating GWT with Nuxeo EP is an attempt to get the best of both worlds: keep JSF for its integration with Seam, third-party JSF libraries, easy deployment/override of xhtml pages as well as existing Nuxeo modules relying on it, and use GWT for some specific complex screens.

An addon has been written as a proof-of-concept. Documents are retrieved from the Nuxeo application via a Seam component and information for their rendering is serialized on the GWT client side to display them in a paginated table.

Seam made life easier by providing a remoting service interacting with the GWT service framework: from GWT rendering classes, it's possible to call a standard Seam component that will implement server logic.

Some code has been added to restore the conversation when calling the Seam component, as we want to display the list of current folder children. The conversation id is retrieved on client side thanks to javascript code parsing the url. It is passed alongside when calling the remote service.

Packaging was not a problem thanks to maven plugins that perform the GWT compilation and make it possible to include them in the nuxeo.war folder at deployment.

Integrating the GWT module within standard xhtml pages was easy: the javascript simply needs to be included in the page as mere html code.

Here's a screenshot of rendered table:

What's next?

Support internationalization: GWT offers different promising internationalization procedures to achieve sharing of translation files *.properties with GWT modules.
Use GWT or GWT-ext libraries modules to customize some complex Nuxeo screens like users, access rights or workflow management.
Provide shared libraries that can be used by other rendering frameworks like Flex, mostly document model serialization.

For better understanding of these technologies, I strongly recommend the excellent article written by Rob Jellinghaus (Seam / JSF / GWT Integration: What, Why, and How: http://unrealities.com/seamgwt/article_0.2.html).

The addon code is at http://hg.nuxeo.org/addons/nuxeo-platform-gwt/. It currently only works with the Nuxeo Seam 2 branch that should be merged in the 5.2 branch shortly.

New Nuxeo newsletter: first issue ever published!

adminsf — 2008-06-16

We have launched last week a new newsletter which we will publish monthly, and will provide “regular insights on our announcements, successes and projects.”

In the first issue:

A big backlog of press coverage (also available as a standalone news item on nuxeo.com).
A focus on our Press Association project in the UK as well as several other significant customers announcements.
Updates on the Nuxeo projects (EP and RCP), documentation and upcoming events related to Nuxeo.

ECM Love, ECM features, ECM sites, ECM goodies!

tsoulcie — 2008-06-10

We have been kept rather busy with Lise since the autumn exhibitions!

From Congress Library. Rights may be reserved.

Everbody loves ECM

Since the bagdes "I (heart) ECM" did very well around us, we developped a whole universe about loving the sweet ECM world! We launched the I love ECM initiative : iloveecm.nuxeo.com. You can follow Mr Jack through hi quest to find the perfect ECM solution.

You can also discover the Nuxeo Crew and download wallpapers!

The campagin included our 2008 greeting card! As usual the card was staff-centered, it was a nice piece of A5 cardboard with a STICKERS sheet inside!

I must admit that numerous people's computers and phones have been "sticked" here at the office, voluntarily... or not! :-)
Please visit our FlickR to have an overall look on the I LOVE ECM material.

Nuxeo Web Engine

While we work on middle-term communication projetcs with Lise, we also have to integrate some of our customers projects. One of theme included a system of web publishing. Some R&D later it became the Nuxeo Web Engine add-on : the ideal way to add public blogs and wikis to your platform! The surprise is not ready yet but will soon be! All I can tell is that is really powerful (tags, comments, attached files, side boxes filling), very smooth to use (it's full of Jquery) yet very simple since it uses Free Markup Language, there is almost no code! I tell you, this will just be awesome 2.0!

Corporate web site

Speaking of Web Publishing, Nuxeo.com had its share : we worked on the front page so the information is more clear and appealing, with less images.

Nuxeo celebrated the World Environment Day and that was the occasion for our web site to change face!

What now?

In addition to all these projects, we have been working for several weeks on a Nuxeo EP interface update. As soon as the wireframes and behaviours are validated we'll start working on the graphics. For now there is not much we can say about the layout and new features, except that it may very well include Jean-Marc Orliaguet's web widgets and that the quality will match Nuxeo Web Engine's. That's to say! :-)

Until there, take care and stay tuned on Nuxeo's Galaxy!

Nuxeo EP 5.1.3.2 released

sfermigier — 2008-02-28

We have released Nuxeo EP 5.1.3.2 earlier this week. This is a maintenance release primarily focussed on bug fixes and small improvements.

You can download it as

a multi-platform installer

or:

a simple ZIP for headless installation

The changelog for this release is available.

Minor, but anyway noteworthy improvements include:

Nuxeo EP now works on a Java 6 JVM, which can lead to significant performance improvements (up to 100% for certain workloads, according to some internal benchmarks).
Full text indexing has been improved and made faster.
Some tweaks have been done to enable communication with the new (soon to be released and announced) “LiveEdit” plugin for Internet Explorer, Firefox and MS-Word.

Interview on ComputerWorld UK

sfermigier — 2008-02-19

I've been interviewed by Glyn Moody, one of the best journalists covering open source, for the ComputerWorld UK web site.

France is not a country many would associate with free software startups, but that's changing – not least because the French government is showing itself far more receptive to open source than its UK counterpart. One of the leading companies of this new Nouvelle Vague is Nuxeo, which was set up by Stefane Fermigier, now its CEO.
