Can I handle array values using JavaBeans?
I could'n find the way to pass an array to JavaBeans.

Below is my situation.

There are four checkboxes.
I want to handle those values in JavaBeans.

----------------------------------------------------------------------------------------------------
1. TestBeanForm.jsp
----------------------------------------------------------------------------------------------------
<form action="TestBean.jsp" method="post">
     <input type="checkbox" name="books"> Java for Student<br>
     <input type="checkbox" name="books"> Compiler Construction<br>
     <input type="checkbox" name="books"> Software Engineering<br>
     <input type="checkbox" name="books"> Core Servlet and JSP<br>
     <p>
     <input type="submit" value="Submit">
</form>
----------------------------------------------------------------------------------------------------

Here, I use JavaBeans.
----------------------------------------------------------------------------------------------------
2. TestBean.jsp
----------------------------------------------------------------------------------------------------
<%@page import="test.TestBean"%>

<jsp:useBean id="testBean" class="test.TestBean">
    <jsp:setProperty name="testBean" property="*"/>
</jsp:useBean>
<jsp:getProperty name="testBean" property="books"/>
----------------------------------------------------------------------------------------------------

When dealing with thoes values using JavaBeans,
Only the first books element is passed to JavaBeans.
Here is my javaBean [sic].

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

public class TestBean {
    private String books;

    public void setBooks(String books) { this.books = books; }
    public String getBooks() { return books; }
}
----------------------------------------------------------------------------------------------------


Where's the array in your bean?
