I have a working Dao manager/SqlMap implementaion for a portal.
How would I change the configuration or implementation so that I can use a diferent dao.xml file at night than during the day without compromising connection pooling etc.
Originaly my dao config looed like this
public class DaoConfig {private static final DaoManager daoManager;
static { try {
String resource = "com/uop/struts/dao/dao.xml";
Reader reader = Resources.getResourceAsReader(resource);
daoManager = DaoManagerBuilder.buildDaoManager(reader);
} catch (Exception e) {
throw new RuntimeException(
"Could not initialize DaoConfig. Cause:
" + e);
}
} public static DaoManager getDaomanager() {
return daoManager;
}
}I then changed it to this :-
public class DaoConfig {private static DaoManager daoManager;
public static DaoManager getDaomanager() {
try {
String resource = null;
Calendar date = new GregorianCalendar();
if (date.get(Calendar.HOUR_OF_DAY) > 8 && (date.get(Calendar.HOUR_OF_DAY) < 20) {
resource = "com/uop/struts/dao/daoDay.xml";
} else {
resource = "com/uop/struts/dao/daoNight.xml";
}
Reader reader = Resources.getResourceAsReader(resource);
daoManager = DaoManagerBuilder.buildDaoManager(reader);
} catch (Exception e) {
throw new RuntimeException(
"Could not initialize DaoConfig. Cause: " + e);
}
return daoManager;
}However each time I call
DaoConfig.getDaomanager() it looks as though it creates a new DaoManager rather than returning the existing one for the current period.
does this make sense? any help greatfully received thanks
