Answer 1

perhaps you can try this ...

<% 
  String ITEM = "";
  ResultSet lRstDet  = null;   

  String SQL  = "SELECT * FROM TB_TEST;
  DB_TEST.makeConnection();      
  DB_TEST.executeQuery(SQL);
  lRstDet = DB_TEST.getResultSet();

  if(lRstDet.next())
  {
    ITEM= lRstDet.getString("ITEM");
  }
  DB_TEST.takeDown();
%> 

--- html part ---
<input type="text" name="ITEM" value="<%=ITEM%>">
