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.
Theses packages all include the fully functional Nuxeo EP platform, including:
the Nuxeo Runtime, which provides the foundation of the Nuxeo components and services based architecture (based on OSGi)
the Nuxeo Core, which provides APIs to core services such as document storage, security, import/export, etc.
the Nuxeo Service Platform, which provides APIs to higher lever services such as search, relations, directories, workflow, publishing, audit, image management, syndication, comments, forum, etc.
the Nuxeo Enterprise Platform (EP), which is a web application built on top of the Service Platform, and includes Nuxeo Theme, a powerful WYSIWYG theming engine developed by Jean-Marc Orliaguet.
the JBoss application server and all necessary third-party libraries.
What’s not included and how do I get it?
Some packages are considered as add-ons, either because they are still a little too “fresh” for general availability, or because they implement functionalities that we believe won’t be useful to the majority of users.
These currently include the WebDAV server, advanced transformers for MS-Office documents, specific login modules for various authentication systems (NTLM, CAS2, mod_sso…), etc.

What’s new in this release?
Here are some highlights since the 5.1.3 release:
Server-side changes to support the new version of our MS-Office plugin, Nuxeo LiveEdit 2 (for more info, check this section of the Nuxeo Book and download the plugin from this page).
Refactoring of web services to use the JAXWS stack.
Lots of performance optimisations.
New or updated translations: Vietnamese (thanks to Le Tuan Dat and Daniel Tellez), Spanish (thanks to Daniel Tellez), Italian (thanks to Mirto Silvio Busico), Japanese (thanks to Damien Dupraz).
Lots of small improvements and bug fixes.
Make Nuxeo compile and run under Java 6.
For more details about what’s been added or fixed since recent releases, please check:
If you need more help, or if you’d like to comment or contribute, please join the mailing list or the forum.
Who should I thank?
This release is brought to you by the Nuxeo development team, which includes around 20 Nuxeo employees as well as several external contributors.
Of invaluable help also are all the customers and more generally users of the Nuxeo platform, specially those who took the time to provide feedback via the mailing list, the forum or he Jira.
What’s coming up next?
We’re already busy working on both Nuxeo 5.1.5 (stable branch) and Nuxeo 5.2 (development branch).
Expect new stable releases (5.1.x) about once per month. New add-ons will also be created and released in parallel to the stable releases.
A Nuxeo 5.2 development release is planned later this spring.
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.
The Nuxeo EP 5.1.3 release is coming along nicely after a small delay due to the holiday break, and will be tagged in a couple of days.
The roadmap for the project in 2008 has been updated accordingly.
Feel free to discuss it in the mailing list or the forum if you have questions, suggestions or to supply missing information.
As can be seen, Nuxeo 5.1.3 will not be just a maintenance release, as we’ve been able to add new features by creating new plugins (ex: WebDAV, Portlets, SSO, etc.) thanks to a now quite stable infrastructure and API.
Nuxeo 5.1.3 will also be based on Nuxeo Runtime and Core 1.4, which feature some improvements while staying compatible with the previous version (1.3). The switch to Nuxeo Core 1.4 was done in December and has proved very stable.
After the 5.1.3 release, we’re going to focus on the 5.2 (trunk) work, so as to move to Seam 2 for the web platform. Most new features will still be developed as new components, and will either be delivered with the next maintenance release (Nuxeo 5.1.4) or with Nuxeo 5.2, or both, depending on technical feasibility and customers needs or community contributions.
You need to install OpenOffice.org separately (by following these instructions) if you want to get the benefits of MS-Office or ODF documents indexing and transformation to PDF.
This maintenance release features performance improvements, bug fixes, and some new functionalities including bulk document importing (see below).
A New and Noteworthy document (PDF, 20 pages) has been written to showcase the major improvements since Nuxeo 5.0, which was released in March.

The release was accompanied by a “New and Noteworthy” document (PDF, 280 kB) which highlights new technical features and functionalities in the release.
Nuxeo 5.1.RC soon to be released
A release candidate (RC) will be tagged this week. The focus of the development team is now bug fixing, with a target release date for the GA version in June.
If you’re willing to shake up the application and look for bugs before the RC is tagged, you can do so by downloading and testing the latest daily snapshot and reporting issues in the projects Jira bugtracker.
Presentation material from the Paris Seminar available
Our customer seminar in Paris on June 7 has been a huge success, with more than 70 attendees and very interesting presentations.
Note: three out of four slideshows are in French. If you can’t read French, you might want to only consider looking at Eric’s slides which give an high-level overview of the new Nuxeo 5.1 platform.
We’re also working on editing the videos that have been shot during the seminar and will be available soon.

“This project is definitely one to watch and even get involved with.” Aaron Walker
Nuxeo 5.1.M2 released
Nuxeo 5.1.M2 (second development milestone towards Nuxeo 5.1 in June) was released last week, with many new features and enhancement. See the
Announcement on nuxeo.org for details.
Inspired by the famous “New and Noteworthy” documents that are published with each Eclipse release and milestone, we have written our own
New and Noteworthy for this milestone.
A lot of work was put into the slides, which are now online, and we hope you will enjoy reading them if you weren’t at the conference.
The slides are also browsable online from Slideshare or just below:
Aaron Walker was at the talk and has some nice comments in is blog (see also “Quote of the week” above).
Slides from the Nuxeo/JBoss event in London
We have also published the slides for the presentations we did in London during the Nuxeo/JBoss event in late April. Note that these were more business-oriented presentation, contrasting with the JavaOne presentation which was purely technical.
We’re hosting a free seminar in Paris on 7 June. If you plan to attend, please register quickly, we’re almost already running out of space.
If you are one of the 500 french software vendors who will attend the “2èmes Assises du logiciel” organized by Syntec informatique, come meet us at our booth.
The Nuxeo team has started working on a “Nuxeo Book”, which will be released with Nuxeo 5.1 in June.
The “draft” is already available online, but be warned that many parts are either not written, or not up to date with the current architecture, as they are being heavily worked on.

Another one is the port (currently half-finished) of the platform to
Glassfish, the Sun open source Java EE 5 application server.
Please read the “New and Noteworthy” document for details on these new features.
We also have added an Italian translation, thanks to Mirto Silvio Busico.
The release has some known issues, including:
