Sure, the <jsp:setProperty> action handles multi-value parameters.
Your JavaBean class needs a set method with a String[] argument, e.g.
public void setNumbers(String[] numbers)
Then you can use <jsp:setProperty> in a JSP page to set the property to
the array of values:
<jsp:useBean name="foo" class="myBean">
<jsp:setProperty name="foo" property="numbers" param="ANumber" />
</jsp:useBean>
To make it even easier you may want to use a name for your form field
that directly match the property name, i.e. replace "ANumber" with "numbers"
in this example (property names should start with a lower case letter).
You can then let the JSP engine figure out which property to set based
on the HTTP parameter name, e.g.
<jsp:useBean name="foo" class="myBean">
<jsp:setProperty name="foo" property="*" />
</jsp:useBean>
