If you have a group of form elements with the same name, as in your
example, all values are made available as a String[] to the servlet
or JSP page that handles the request. In servlet code, you get access
to the array with getParameterValues("theFieldName"). In JSP, you can
use the same code in a scriptlet, but to avoid code in the page it's
typically better to use a bean with a String[] property:
<jsp:useBean id="formData" class="myFormHandler">
<jsp:setProperty name="formData" property="*" />
</jsp:useBean>
The class has a setter method like this, assuming the field name
(parameter name) is, literary, "fieldName":
public void setFieldName(String[] values) {
...
}
You may also want to look at developing a custom action to process
the data.
