Working fine on Tomcat 5.0 but not on 5.5.7

[micky none]

Hi Friends,
I have this simple method which works fine on my system(Tomcat 5.0,jdk 
1.5)..but not on the server(Tomcat 5.5.7,jdk1.5).Can someone explain me why:


-----------------------------------------------------
String syear = null;
int selectedYear = 0;
try{
syear = request.getParameter("year");
  if (syear != null){
  selectedYear = Integer.parseInt(syear);
  session.setAttribute("syear_sess",new Integer(selectedYear));
  }
  else{
  if(session.getAttribute("syear_sess") != null)
    selectedYear = ((Integer)session.getAttribute("syear_sess")).intValue();
  else
  {
        syear = "2005";
    selectedYear = Integer.parseInt(syear);
  }

}
}catch (IllegalArgumentException _e){
    throw new Exception("selectedYear error");
}
----------------------------------------------
"year" is a combo box name.The error this code throws is:
