Answer 1

QCDataInfo condInfo;
if(conditions!=null){
     ListIterator li = conditions.listIterator();
while (li.hasNext()) {
condInfo = (QCDataInfo) li.next();
stmt = conn.getConnection().prepareStatement(sql);
     stmt.setLong(1, JLong.forceLong(loanId));
     stmt.setString(2,condInfo.getCategory());
     stmt.setString(3,condInfo.getCleared());
     stmt.setString(4, condInfo.getMessage());
     stmt.setString(5, condInfo.getNotes());
     System.out.println(condInfo.getCategory()+"=dtstus="+condInfo.getCleared()+"=execute:="+stmt.executeUpdate());
public static List getQCDataInfo(String loanId)
throws ACTPortalException {
info = new ArrayList();
int x=0,a=0,b=0,c=0,d=0,e=0,f=0;
while(rs.next()) {
     QCDataInfo xform=new QCDataInfo();
     xform.setCategory(rs.getString("category"));
xform.setCleared(rs.getString("cleared"));
xform.setMessage(rs.getString("message"));
xform.setUpdated(rs.getString("updated"));
xform.setNotes(rs.getString("notes"));
if(rs.getString("category").equals("Occupancy")){
xform.setIndex(x);x++;
          }else if(rs.getString("category").equals("Liabilities")){
               xform.setIndex(a);a++;
          }else if(rs.getString("category").equals("Assets")){
               xform.setIndex(b);b++;                    
          }else if(rs.getString("category").equals("REO")){
               xform.setIndex(c);c++;
          }else if(rs.getString("category").equals("Collateral")){
               xform.setIndex(d);d++;
          }else if(rs.getString("category").equals("Employment and Income")){
               xform.setIndex(e);e++;
          } else if(rs.getString("category").equals("Other")){
               xform.setIndex(f);f++;
// System.out.println("data:"+rs.getString("category")+":row number:"+rs.getRow());
info.add(xform);
return (info);
the above are 2 methods where i am getting class cast exception
