"I have a couple of Struts 2 sites running over db4o object database, and I have
never had such a smooth job of developing code. I only had to think about one thing
-- objects! No mapping files, XML, table names, join strategies..."

-- db4o 7.1 MAKES PERSISTENCE TRANSPARENT --
db4o 7.1 has reached the goal of making persistence totally transparent. Transparent
Persistence is the result of combining Transparent Activation, introduced with db4o 7.0 and Transparent
Update, introduced in this most current release.
Transparent Update persists objects without any explicit command. The code looks
no different than non-persistent code except for the benefit of transaction semantics.
Read more about Transparent persistence in Rodrigo's Blog post and in the press release. Registered users of db4o can download
the software from the db4o developer site.
-- XtremeConnect ENJOYS GREAT DEMAND --
Since the introduction of XtremeConnect in November customers have benefitted from
over 140 hours of one-on-one time with db4o specialists.
XtremeConnect is a component of the dDN Enterprise offering introduced in November
2007. It allows developers to directly connect with a db4o specialist for a remote
pairing session that enables joint design reviews, problem solving or debugging
with unprecedented efficiency.
Customer feedback on these new services has been overwhelmingly positive.
Please visit the db4o web site to learn more about dDN Enterprise and XtremeConnect.
-- ObjectManager ENTERPRISE FOR ECLIPSE RELEASED --
The Eclipse version of ObjectManager Enterprise for Java developers is now available
to dDN Enterprise subscribers.
ObjectManager Enterprise is a completely new design of the ObjectManager productivity
tool for database browsing and maintenance. ObjectManager Enterprise was introduced
in November 2007 as a Visual Studio plugin for .NET developers. Now Java developers
can enjoy the same productivity benefits.
ObjectManger Enterprise is designed as a plug-in to the Eclipse IDE, leveraging
the capabilities and features of Eclipse and allowing Java developers to remain
in their favorite development environment.
You can find more information on ObjectManager Enterprise on the web.

-- 2007 IN REVIEW --
We would like to take the opportunity to wish everyone a happy new year and thank
you for all the contributions and support you have provided in 2007.
Here is a sample of what you have helped achieve:
- The developer community has grown to 30,000 users
- Downloads of db4o doubled last year to a cumulative total of nearly 2M
- We are proud to count 110 members of our community as
dVPs (db4o Most Valued Professionals),
double the number from last year
- There are close to 100 projects
None of this could have been done without you – Thank you!
-- db4objects INTRODUCES CodeCommander PROGRAM --
The CodeCommander program is designed to identify projects that are of particular
importance to both the community and the direction of db4o and to assure the timely
and successful completion of these projects.
Specifically the program defines a range of incentives such as collaboration with
core team members (including pairing sessions), monetary rewards, access to development
infrastructure for project support and marketing of successful projects to a large
user community for fast adoption.
To learn more about the program please visit the CodeCommander page.
-- STRAIGHT FORWARD PERSISTENCE FOR WICKET --
"A Little Persistence Framework for Wicket" by Tim Boudreau is available in the code snippets section. It demonstrates how to leverage
db4o in Wicket web applications.
Apache Wicket is a web application
framework that features a proper mark-up/logic separation, a POJO data model, and
a refreshing lack of XML focused on providing reusable components written with plain
Java and HTML (certainly a perfect fit for db4o!).
-- JPOX "db4o" PLUGIN VERSION 1.2.0-BETA-5 RELEASED --
This plugin provides persistence to db4o datastores using either the JDO1.0/2.0/2.1
API or the JPA1.0 API. Changes in this release include:
- Querying using JDOQL - initial release, supporting the majority of available JDOQL
features
- Bug fixes for transaction handling, and application identity
- Addition of support for auto-start mechanisms, notifying JPOX of "known" classes
for efficiency
- Minimized the memory overhead of collection/map wrappers Support for relative file
paths in file-based DB4O persistence
In addition to this plugin release, JPOX "Core" module provides support for many
new features for JDO2.1. Read more in the db4o JPOX Project page and the JPOX web site.
-- HOW TO USE db4o WITH MOZILLA RHINO SCRIPT ENGINE --
Jim Morris
has contributed an example of how to use db4o with Mozilla Rhino Script Engine.
Mozilla Rhino is an open-source implementation of JavaScript written entirely in
Java. It is typically embedded into Java applications to provide scripting to end
users. Read more on in the Useful Snippet section of the db4o developer site.
