How to store session variables in drop down menu (and radiobutton/checkbox)

Question

How am I going to store session variables in the drop down menu, radio button, checkbox.
In text area, I do like below:
<input type="text" name="membershipno" size="5" maxlength="50" value="<%=((session.getValue("Smembershipno")!=null)?session.getValue("Smembershipno"):"") %>">
Any idea?

Hi jeffkyt79, I could have answered this on Expert's Exchange. But I suppose it would be hard as the site is down right now :-(
Here is sample code for the form:
<form action="" name="form1">
<input type="text" name="field1" value="<%
if (session.getAttribute("field1")!=null) {
out.println(session.getAttribute("field1"));
} %>"><br>
<input type="text" name="field2" value="<%
if (session.getAttribute("field2")!=null) {
out.println(session.getAttribute("field2"));
} %>"><br>
<input type="text" name="field3" value="<%
if (session.getAttribute("field3")!=null) {
out.println(session.getAttribute("field3"));
} %>"><br>
<input type="checkbox" name="check1" value="tick"<% if (session.getAttribute("check1")!=null) out.println(" checked"); %>><br>
<% String selRadio=(session.getAttribute("r1")!=null)?(String)session.getAttribute("r1"):""; %>
<input type="radio" name="r1" value="yesdot"<% if (selRadio.equals("yesdot")) {out.println(" checked");} %>>
<input type="radio" name="r1" value="nodot"<% if (selRadio.equals("nodot")) {out.println(" checked");} %>><br>
<select name="sel">
<% String selOption=(session.getAttribute("sel")!=null)?(String)session.getAttribute("sel"):""; %>
<option value="option1"<% if (selOption.equals("option1")) {out.println(" selected");} %>>OPTION 1
<option value="option2"<% if (selOption.equals("option2")) {out.println(" selected");} %>>OPTION 2
     <option value="option3"<% if (selOption.equals("option3")) {out.println(" selected");} %>>OPTION 3
</select>
</form>
And here's the revised javascript function to put in form1.jsp:
function newWin() {
f=document.form1.elements;
str="?";
mypage="test2.jsp"; // I've hardcoded the url for testing but you can fix this
for (i=0;i<f.length;i++) {
if (f.type=="text") {
if (f[i].value!="") {
str=str+f[i].name+"="+f[i].value+"&";
          continue;
     if (f[i].type=="checkbox"||f[i].type=="radio") {
     if (f[i].checked) {
     str=str+f[i].name+"="+f[i].value+"&";
     if (f[i].type=="select-one") {
     str=str+f[i].name+"="+f[i].options[f[i].selectedIndex].value+"&";
str=str.substr(0,str.length-1);
// now open the popup
mypage+=str;
win=window.open(mypage, 'myname'); // I've left out the winprops but you can fix this
If you can ask any more questions, could you do it on EE (if possible!!). I know this works because I've tested it.
