Organizatorium

According to JDBC Javadoc, a DataSource is a factory for connections to the physical data source that this DataSource object represents.

An object that implements the DataSource interface will typically be registered with a naming service based on the JavaTM Naming and Directory (JNDI) API.

Example: {{{

      DataSource ds = (DataSource)ic.lookup("java:/DefaultDS");
      Connection conn = ds.getConnection();

      ....

      conn.close();
