Multi select box to JSP

[Kyupa Supa]

In 1st JSP page I have a form with multi-select box. After user choses the values, I want to display them in a table in 2nd JSP page, but i see only the vector's name. Means, when displaying sids[i], I get only the name "sids" in the table.

In 1st JSP page I have:

<select id = "mySelect" multiple name = "sid" size = "5">
        <% for (Student st : students){%>
         <option value="cid"><%= st.getStudent_id() %></option>
        <%}%>
</select>       

User presses "Link" button so the next JSP page is displayed.

<td><input type="submit" value = "Link"/></td>

In the 2nd JSP page:

if((request.getParameterValues("sid") != null) && (request.getParameterValues("cid") != null)){ 
		
		String sids[] = request.getParameterValues("sid");

<table> 
      <tr>
          <td bgcolor= #FF9966><b>SID</b></td>
      </tr>

       <tr>
       <% for (int i = 0; i < sids.length; i++){%>
	<tr>
	<td><%= sids[i] %></td>
	</tr>
       <%}%>
       </tr>

1.

<option value="cid">

for all the option values associated to one key/label ? which is wrong

2.

request.getParameterValues("cid") != null

why this check? remove it.

for all the option values associated to one key/label ? which is wrong

But I don't know how many values are

Why is the value of all the options the string "cid"?

I notice the problem now; I fixed it as so:

<select id = "mySelect" multiple name = "sid" size = "5">
                             <% for (Student st : students){%>
                                   <option value="<%= st.getStudent_id() %>"><%= st.getStudent_id() %></option>
                                <%}%>
                         </select>

And it posts the user chosen values to the next page now :)
