How to get multiple values from the list

Question

I've a list of an item which I queried it from the database. I also created a button that will takes a selected items from the list when it was clicked. I used javabean to get the data from database.
<%     // clicked on Select District Button
Vector vselectedDistrict = new Vector();
Vector vdistrictID = new Vector();
String tmpSelectDistrict = "";
tmpSelectDistrict = request.getParameter("bSelectDistrict");
if(tmpSelectDistrict != null)
     // get multiple values from the list
     String[] selectedDistrict = request.getParameterValues("usrTDistrict");
     vselectedDistrict.clear();
     vdistrictID.clear();
     if((selectedDistrict != null) && (selectedDistrict.length != 0))
                         for(int i=0;i<selectedDistrict.length;i++)
               vselectedDistrict.addElement(selectedDistrict);           
          vdistrictID = dbaseInfo.getcurrentDistrictID(nstate,vselectedDistrict);
          for(int i=0;i<vdistrictID.size();i++)
               out.println("district = " + selectedDistrict[i]);                         out.println("district ID= " + vdistrictID.get(i).toString());
%>
// get vdistrict from the database here......
<select name="usrTDistrict" size="5" multiple>
<%     for(int i = 0; i< vdistrict.size(); i++)
%>
     <option value="<%=vdistrict.get(i).toString()%>"><%=vdistrict.get(i).toString()%></option>
<%
%>          
</select>
<input type="submit" name="bSelectDistrict" value="Select District">
Lets say the item that i selected from the list is 'Xplace' and I clicked on the Select District button,
what I got is this error message:
org.apache.jasper.JasperException: Unable to convert string 'Xplace' to class java.util.Vector for attribute usrTDistrict: java.lang.IllegalArgumentException: Property Editor not registered with the PropertyEditorManager
So where is going wrong and what the message means?. Any help very much appreciated. Thanks

These are just guesses that might hopefully steer you in directions you haven't looked in yet.
I presume you used triangle brackets (< >) to avoid having the Jive Forum think it was the "italics" tag?
Are you certain this: dbaseInfo.getcurrentDistrictID(nstate,vselectedDistrict);
expects a Vector as its second parameter? And returns a Vector?
I don't believe you've shown how you use the javabean, or its code? Perhaps it should be rewritten to accept an array of strings instead of a Vector?
