TypeHandler for java primitive
Hi,
You know, when you set resultClass properties to java primitive type
such as "int", NullPointerException occures if its corresponding Table
Column value is null.
You can suppress those Exception by setting "nullValue" property to
each column in SQL Map xml. But, it is very messy work.
So, I want to set TypeHandler for int type property in SQL Map Config.
But my attempt failed. I'm sorry but TypeHandler for java primitive type
doesn't work.
Is it a bug or iBATIS policy?
thanks,

Messier than mapping a null value to a variable that cannot contain null values?
I have to disagree.

hi,
> Why not just use Integer?
I think it is a little bit messy
to calculate the numeric property
when you use Integer because you
have to use Integer.intValue method.
Don't you think so?

Why not just use Integer?
