Dynamic Update of Combo Boxes with Struts

Question

I need to update one dropdown box based off of the selection of the other. When I select an option I am using an onchange="reload()" to reload the page. The problem with this is as far as I can tell is only refreshing the html in the browser and not sending a new request back to the server. I have the tags bellow. If any one has any Ideas I would appreciate it.
<bean:size id="planCount" name="new_enrollment_newEnrollmentForm" property="newEnrollmentTO.coverages[${status.index}].classPlans" scope="session"/>
<c:choose>
     <c:when test="${planCount > 1}">
          <html:select name="new_enrollment_newEnrollmentForm" property="coverages[${status.index}].classPlanID" styleClass="coveragePlanDropDownSize" onClick="window.location.reload()" >
                    <html:option value=""/>
                    <html:options name="new_enrollment_newEnrollmentForm" property="coverages[${status.index}].classPlans" />     
          </html:select>
     </c:when>
     <c:otherwise>
          <c:out value="${coverage.classPlanID}"/>
     </c:otherwise>
</c:choose>
<bean:size id="volumeCount" name="new_enrollment_newEnrollmentForm" property="newEnrollmentTO.coverages[${status.index}].volumes" scope="session"/>
<c:choose>
     <c:when test="${volumeCount > 1}">
          <html:select property="newEnrollmentTO.coverages[${status.index}].volume" styleClass="volDropDownSize">
               <html:option value=""/>
               <html:options name="new_enrollment_newEnrollmentForm" property="coverages[${status.index}].volumes"/>     
          </html:select>
     </c:when>
     <c:otherwise>
          <c:out value="${coverage.volume}"/>
     </c:otherwise>
</c:choose>

Yes, you are correct. Using the JavaScript reload() function will not submit anything to the JSP. Try something like onchange="document.forms[0].submit()" or something like that. JavaScript isn't my strong suit.
