unable to perform redirect think its a problem with tomcat

[bob peck]

im passing information from a form.
the page that accepts the form data tests the fields then if any fields are missing it will redirect with the parameters that are missing
but im getting an error with the redirect code, and im not sure why: here is my code, i'll post the error underneath. im not very good at reading error messages yet.
i think the problem is with my server, but i dont know how to troubleshoot.

here is my code that is causing the error

	<c:if test="${param.name eq '' or param.address eq ''}">
		<c:set var="name" value="${param.name}" scope="session"/>
		<c:set var="address" value="${param.address}" scope="session"/>
		<c:redirect url="pizza.jsp">
			<c:if test="${param.name eq ''}">
				<c:param name="name" value="missing"/>
			</c:if>
			<c:if test="${param.address eq ''}">
				<c:param name="address" value="missing"/>
			</c:if>
		</c:redirect>
	</c:if>    

here is my error message.
