As you already know, the default value of checkbox is "on" or "off"

Although I didn't set values of checkboxes, there is no problem.

Do you agree with me? (I think you will.)

I can receive checkbox values as an array If I use getParameter() in
Servlet.

However, when I handle it using JavaBeans, I cannot receive the
checkbox values as an array.

That's my problem. And I didn't ignore your advice ever!

I am not sure, but I might read that JavaBeans cannot handle array
values.

If you want to deal with array values, you need to use Tag Library.

Anyway, sorry for late reply. I've been so busy.
