Thanks Gareth,
It's clear for me now.

The classes used in iBatis need to conform to the JavaBeans spec - they need to have a no-arg constructor.

If you really need to use the class with a string constructor, I'd suggest returning a Map from the sqlmap queryForObject method, then constructing your java object in your DAO.

I use iBatis as my DAO Layer for now. It works fine with no-args
constructor class.
Then it can setter properties in result map.
But If I have a class without no-args constuctor, how to instantiate
in iBatis,  As there is a column in selection that can be used to pass
in constructor to create a new instance, how to achieve this goal.

Ahh how about you just add an empty constructor...

public TestA() {
    this("");
}

Problem solved.
