session初级问题，救救我吧:

Question

那逗号是否有问题？schNo的定义是否有问题？你再查查

Answer 1

郁闷了一小时啦！代码详见：
........
public void doPost(HttpServletRequest req,HttpServletResponse res) throws IOException,ServletException{String act=req.getParameter("action");
String schNo=req.getParameter("schNo");
String retURL="crs_error.htm";
HttpSession session;
int result;
SchIndexBean schIndxBean; 
SchCourseBean schCrsBean=new SchCourseBean();if (act!=null){
     if ("add1".equals(act)) {
//String crsNo=req.getParameter("crsNo");
schIndxBean=new SchIndexBean();
schNo=CodeTrans.UniToCn(schNo);
result=schIndxBean.getSchIndex(schNo);
if (result==0) {
schNo=CodeTrans.CnToUni(schNo); session=req.getSession();             //
session.setAttribute("schNo",schNo);  //这里附近
req.setAttribute("schIndxBean",schIndxBean); // RequestDispatcher rd=getServletContext().getRequestDispatcher("/html/schCrs_add1.jsp");
rd.forward(req,res);
}
