Hi Satish,
To my mind the easiest solution would be one from developer's guide (last option Lars suggested). But it is quite limited, because there You can't override ORA messages like ORA:022XXX in general, there You must list specific DB constraints in two-dimensional array. In this solution I also missed just simple "error code -message" mapping in regular bundle file. It is not described in developer's guide, but easily implemented by just creating bundle file in the same package as extending class resides (more details in blog post Custom bundle to override default error mesasges in ADF application).
But.. If You still need to override DB messages like ORA:022XXX, not particular constraints, You should go with rth suggested solution.
Here is a code sample of "DCErrorHandlerImpl" extending class to set You on the road:
public class DataControlExceptionHandler extends DCErrorHandlerImpl {
    public DataControlExceptionHandler() {
        super(true);
    @Override
    public String getDisplayMessage(BindingContext bindingContext, Exception exception) {
     if (exception instanceof SQLIntegrityConstraintViolationException) {
            SQLIntegrityConstraintViolationException sqlExc = (SQLIntegrityConstraintViolationException) exception;
           return "DB exception occured: "+ sqlExc.getMesage();
        return exception.getLocalizedMessage();
