*[2] Inclusion of DatabaseConfiguration in configuration.xml*
It woould be nice to introduce something like <database> tag in
configuration.xml. The content of the tag would be connection string for
the database. Example:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<configuration>
<xml fileName="prop1.xml"/>
<xml fileName="prop2.xml"/>
<properties fileName="prop3.properties"/>
<database
connect="jdbc:mysql://delovc10.noviforum.si/feeds?user=foo&password=bar"/>
</configuration>
For this we might provide a simple way of configuring a
DatabaseConfiguration by fetching a DataSource through JNDI. The
configuration descriptor would look like this :
<configuration>
<database jndi="jdbc/MyDB" table="conf" keyColumn="key"
valueColumn="value"/>
</configuration>
We may also propose to configure a DataSource using DBCP with attributes
specifying a driver name, URL, user and password. But I'm not sure I
want to enter this territory, sooner or later we'll be asked to provide
a way of configuring the connection pool, changing the implementation,
tunning the parameters, etc.. and that's not really the responsibility
of [configuration]. ConfigurationFactory should remain a simple way or
building a configuration declaratively, it should not turn into a
complex configuration framework.
