<h1>Db4o-Osgi Usage</h1><p><font color="#990000">This topic applies to Java version only.</font> </p><p>db4o-osgi service can be accessed like any other OSGI
service:</p>
<p><code>ServiceReference serviceRef =
_context.getServiceReference(Db4oService.class.getName());</code></p>
<p><code>Db4oService db4oService =
(Db4oService)_context.getService(serviceRef);</code></p><p>db4o-osgi uses Bundle-ActivationPolicy:lazy header to define the lazy bundle loading policy (only utilized in some environments, like Eclipse).</p><p>Db4oService instance can be used as Db4o class in usual
environment:</p>
<p><code>Configuration config =
db4oService.newConfiguration();</code></p>
<p><code>ObjectContainer db = db4oService.openFile(config,
filename);</code></p>
<p>Also available are methods for opening db4o server and
client. For more information see the API documentation.</p>
<p>Once the service instance is obtained, you can continue to
work with db4o API as usual.</p>
