<frameset rows="70,*,20" cols="*" border="0" framespacing="0"> 
  <frame src="/mainPage_head.jsp?<%=sessParm%>" marginwidth="0" marginheight="0" frameborder="NO" scrolling="NO" name="top">
  <frameset cols="200,*" rows="*"> 
    <frame src="/mainPage1_left.jsp?<%=sessParm%>" name="left" marginwidth="0" marginheight="0" scrolling="NO" frameborder="NO">
