I got rid of the code about array.
Original code is here.

---------------------------------------------------------------------------
-------------------------
3. TestBean.java
---------------------------------------------------------------------------
-------------------------
   package test;

   public class TestBean {
   private String[] books;
   public void setBooks(String[] books) { this.books = books; }
   public String[] getBooks() { return books; }
}
---------------------------------------------------------------------------
-------------------------

However, when I pass multiple check box values,
A browser only can receive just first one value in checkboxes.
Do you know how to handle array values in JavaBean?
