Question

I am making a form of registering details of competitive exams.in this i am using the jstl for fetching the values fromthe database
like qualification table is master table and the eligibilty table .
these two tables are drop down list and depend on one another
in the sense ...eligibility table when u select multiple values from it then an event onblur will make the changes in the qulaification drop down list.
the list of values from the master tables are taken to the bean first and then into the form and also all the getter and setter methods are also there in it
the code for it is as follows:
bean
private String examinationName;
     private List eligibilityList = new ArrayList();
     private List qualificationList = new ArrayList();
     private List sourceList = new ArrayList();
     public CompetitiveExamBean() {
     eligibilityList = DAOMaster.getQualificationMaster();
     if(eligibility!=null) qualificationList=DAOMaster.getQualificationDetail(eligibility);
     sourceList = DAOMaster.getSourceList();
jsp page
(Code for eligibility)
<select name="eligibility" style="width:220pt" multiple size="4" onblur="changeQualification()">
<c:forEach var="elb" items="${competitiveExamBean.eligibilityList}">
<option value="${elb.id}"
     <c:forEach var="selEligi" items="${competitiveExamBean.eligibility}">
     <c:if test="${elb.id==selEligi}"><c:out value="selected"/></c:if></c:forEach> >
     <c:out value="${elb.value}"></c:out>
</option>
</c:forEach>
</select>

<select multiple name="qualification" style="width:220pt">
<c:forEach var="selq" items="${competitiveExamBean.qualificationList}">
     <option value="${selq.id}"
               <c:forEach var="selQuali" items="${competitiveExamBean.qualification}">
