<!--
An example/default DataSource that uses
Oracle JDBC-driver to create the connections.
This tag creates all the needed kinds
of data-sources, transactional, pooled and EJB-aware sources.
The source generally used in application code is the "EJB"
one - it provides transactional safety and connection
pooling. Oracle thin driver could be used as well,
like below.
url="jdbc:oracle:thin:@host:port:sid"
