select box problem

Hjava
Member Posts: 406
I have a simple drop down box with the select item out of db
like if the value in my db is i then the user will see two line of <option value="1">1</option>,
is that a simple way to handle this problem?
<c:if test="${found.year=='1'}">
<option value="1" selected>1</option>
<c:if test="${found.year!='1'}">
<option value="1" >1</option>
since if the select list is long , like to 100 then the code will turn to every long , should be have a better way , is that right??

I try the follow, but the value out of my db never get select , what is wrong in the if condition??
<%ArrayList<Integer> tyear = new ArrayList<Integer>(); for (int i = 1; i <= 10; i++) { tyear.add(i); } <select name="year"> <% for (Integer num : tyear) { String aY = Integer.toString(num);%> <c:if test="${found.year==aY}"> <option selected value="${found.year}"> <c:out value="${found.year}"/></option> </c:if> <c:if test="${found.year!=aY}"> <option value="<%= aY%>"><% out.println(aY);%></option> </c:if> <%}%> </select>
