Solstice is the first framework to integrate Flex, OSGi and db4o in a single out-of-the-box package. Even though it's still in alpha, it provides a rich set of open source products and technologies, including Adobe Flex, Adobe BlazeDS, OSGi, Eclipse Equinox, Eclipse Equinox Servlet Bridge, JBoss, Felix and db4o.   So far it provides the ...

Hi, I'm trying to get db4o to run on Concierge OSGi. The application is for Bug Lab's (buglabs.net) platform, so it needs to use that framework. Unfortunately I hit two snags. One is on reflection the Db4oServiceIml, in the last method the config.reflectWith(new OSGiReflector(_bundle)); can not find the OSGiReflector The other is in the class ...

The db4o reference documentation about OSGi: http://developer.db4o.com/Resources/view.aspx/Reference/Platform_Specific_Issues/Database_For_OSGi seems to answer some of the questions in this forum. If you would like to see something else or correct something on the documentation please answer to this thread with suggestions. Best regards.

I'm starting the db4o service in Equinox, as a bundle; however, it's unable to find the DB4O Container, as mentioned in another post. Is it expected that I deploy the db4o jar along with the bundle which has the Db4o dependency, such that the db4o service *only* provides the way to get the container, but not the container itself?

Hello, I'm writing an OSGi application with an db4o database and I have problems storing objects into the db4o database. My environment is as follows: - Windows XP, Eclipse 3.3, db4o version 6.4 As OSGi implementation I'm using Equinox. When I'm trying to run a bundle inside my eclipse environment and I try to store something to the database, ...

I'm not sure which OSGi framework you are using. If you are running on Eclipse Equinox then you can make use of an Eclipse specific extension called ''buddy classloading''. However, this limits your ability to run your bundles on other OSGi frameworks. Basically, you would create a DB4O bundle and add the following to it's bundle ...

Hi, I have a bundle which which exposes an instance of ObjectContainer, let's call this the ''arum.db'' bundle.  This bundle uses a ServiceTracker to track db4o_osgi.  During the ''addingService'' method of my tracker, I get the Db4oService service and call service.openFile().  I then register a service which my other bundles can ...
