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=

<input type="checkbox" name="books"> Comp=

<input type="checkbox" name="books"> Core=

<p>
<input type="submit" value="Submit">
</form>

Here, I use JavaBeans.

<%@page import="test.TestBean"%>
<jsp:useBean id="testBean" class="test.TestBean">
<jsp:setProperty name="testBean" property="*"/>

<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?

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?
