Exception not catched...

Question

Friends,
I am using this :
File file = new File(path2upload);
                                if(!file.exists()){ file.mkdirs(); }               
                    if (!file.exists())
                         file.createNewFile();
                    factory.setRepository(file);
                          // Create a new file upload handler
                    ServletFileUpload upload = new ServletFileUpload(factory);
                                try {
                               //RESTRICT FILE SIZE TO 10 MB
                                upload.setSizeMax(FILESIZELIMIT);
                                }catch(Exception e)
                                 {  response.sendRedirect("index.jsp"); out.println("SIZE EXCEEDED"); }Since i want to redirect the page when it should through the exception
for the size.
when i give larger file than 10 mb it should give me following error :
HTTP Status 500 -
type Exception report

Answer 1

Is this business logic put in the view page (the JSP) ? If so, don't do that. Use JSPs for view only and use servlets/beans for business logic.
