Help: List/Menus on jsp

Question

can you please help me out on this one. I have questions table, answers table and student info table on my database.
<form METHOD="POST" name="form1">
here I want to get the number of subjects and store in (x).
<%
String[] subjects = {(String)rstry.getObject("subj1"),(String)rstry.getObject("subj2"), (String)rstry.getObject("subj3"), (String)rstry.getObject("subj4"),(String)rstry.getObject("subj5"), (String)rstry.getObject("subj6"), (String)rstry.getObject("subj7"), (String)rstry.getObject("subj8"), (String)rstry.getObject("subj9"), (String)rstry.getObject("subj10")};
for (int i=0; i < subjects.length; i++)
     if ( !subjects.equals(""))
               x = x + 1;
%>
here I'm getting the qestions
<%
     String[] questions = {(String) qsn.getObject("Q1"),qsn.getString("Q2"), qsn.getString("Q3"), qsn.getString("Q4"),qsn.getString("Q5"), qsn.getString("Q6"), qsn.getString("Q7"), qsn.getString("Q8"), qsn.getString("Q9"), qsn.getString("Q10")};
%>
here I create a table rows and columns are determined by the number of subjects(x) and number of questions.
Then depending on number of subjects I display the List/Menu to answer each question by subject.
after this I want to submit the answers i.e. List/menu to answers table but its submitting one answers i.e. List/menu 1.
how can i overcome this. I mean how can I get the value for the rest of List/menu
<table border= "0">
<tr bgcolor="red" height = "50">
<td>QUESTIONS</td>
<% for( int z = 0; z < x; z++){%>
<td bgcolor= >(<%= subjects[z]%>) </td>
<% }%>
<% for( int y = 0; y < 10; y++){%>
<tr>
<td bgcolor="#FF66CC"> <%= questions[y] %></td>
<% for( int a = 0; a < x; a++){%>
<td bgcolor="#66FF33"> <select name="select">
<option value="1">strongly disagree</option>
<option value="2">disagree</option>
<option value="3">agree</option>
<option value="4">strongly agree</option>
</select> </td>
<% }%>
</tr>
<% }%></tr></tr>
</table>
<p>Type your general comments here:
<textarea name="textarea"></textarea>
</p>
<p align="center">
<input type="submit" name="Submit" value="Submit" >
</p>
<input type="hidden" name="MM_insert" value="form1">
</form>
I hope you can help.
Thanks!!

it's quite normal not all of the feilds gets submitted. what you need is to create the table rows for answers in a loop and store them in an array (if you want to use the same name for all the answer select lists) in the page that you submit the info to.
here's a snippet:
this is where i create the <input>s for the form (note that all the names for the <input>s will be the same when the loop runs)
while(dba.next())
%>
<tr>
<td><%=dba.getString("ref_en")%><input type='hidden' name='refEn' value='<%=dba.getString("ref_en")%>'> / <%=dba.getString("ref_tr")%><input type='hidden' name='refTr' value='<%=dba.getString("ref_tr")%>'></td>
<td align='center'><input type='text' class='admin_body' name='lang0' size='20' maxlength='50' value='<%=dba.getString("lang_0")%>'></td>
<td align='center'><input type='text' class='admin_body' name='lang1' size='20' maxlength='50' value='<%=dba.getString("lang_1")%>'></td>
<td align='center'><input type='text' class='admin_body' name='lang2' size='20' maxlength='50' value='<%=dba.getString("lang_2")%>'></td>
<td align='center'><input type='text' class='admin_body' name='lang3' size='20' maxlength='50' value='<%=dba.getString("lang_3")%>'></td>
</tr>
<%
this is where i catch them
if(action.equals("updateKeywords"))
String[] refEn = request.getParameterValues("refEn"); // here we get parameters from the posting page into an array. obviously there are many "refEn" parameters coming from many <input> fields with the same name.
String[] refTr = request.getParameterValues("refTr");
String[] lang0 = request.getParameterValues("lang0");
String[] lang1 = request.getParameterValues("lang1");
String[] lang2 = request.getParameterValues("lang2");
String[] lang3 = request.getParameterValues("lang3");
hope this helps.
