Model has int but database is a Number

[Mississippi John Hurt]

Hi,
What's the best way to handle this? My db column is a NUMBER where 0 has meaning, so does 1.
My model has a property that's an int. But int's by default are 0 (which have meaning). So my dynamic map statement cannot tell if the int value of 0 is set by me or by default 0. So other than having another say java boolean indicator, how can I get around this best? Other than making the property a Integer object which will force me to add extra java code everywhere to convert from int to Integer?  Thanks.
