Question

I have a sql statement that pulls infomration about tagnum’s for individual pidm’s. Every pidm can have multiple tagnum’s so I am dropping the information into an arraylist. I want to display the contents of this arraylist in a dropdown box on a html page.

Here is the code for the arraylist:

       <table style="border:transparent" style="width:100%">
            <tr>
             <td style ="width: 300px;">
             <select style="width:150px;"tabindex="5" name="Tag">
                 <option></option>
<%} rscheck.close();
     ResultSet rsTagCheck = stmt.executeQuery("SELECT PARKING.XKRPRMT.XKRPRMT_PIDM, PARKING.XKRPRMT.XKRPRMT_STATUS, PARKING.XKRPRMT.XKRPRMT_EXPIRE_YR, PARKING.XKRPRMT.XKRPRMT_TAG FROM PARKING.XKRPRMT WHERE XKRPRMT_PIDM ='" + BannerID + "'");

     while (rsTagCheck.next()){
            ArrayList<String> myTag = new ArrayList<String>();
            myTag.add(rsTagCheck.getString("XKRPRMT_TAG"));         
%>              
                  <option><%= myTag.get(0) %></option>
             </select>
             </td>

I can get the first element to show in the drop down box, but anything after that show an outofbounds exception. I want to know how to display ALL of the information in the arraylist.

@Pointy I did that and all I got was this:

It put the first one in there, but the rest would not populate!!

There’s no reason to create the array list at all.

while (rsTagCheck.next()) {
  %>
  <option><%= rsTagCheck.getString("XKRPRMT_TAG") %></option>
  <%
}

edit — of course in practice you should be careful about what those strings might contain. If the strings come from some sort of user input, you shouldn’t be just dumping them unwashed into the HTML. That’s a whole other subject however.
