Configure the component. This class is expecting a configuration like the following one:

<driver>org.dbxml.client.xmldb.DatabaseImpl</driver>
<base>xmldb:dbxml:///db/</base>

NOTE: the driver can be any DB:XML compliant driver (although this component has been tested only with dbXML, and the trailing slash in the base tag is important!

Parse the requested URI, connect to the XML:DB database and fetch the requested resource.

Initialize the component getting a database instance.

Recycle the component, keep only the configuration variables and the database instance for reuse.
