Assalamoalikum Dear this is due to the variable which you wants to prints its value but value is not yet assigned. So check out the variables defined in your jsp page or servlet.Generally some variables value depends on the request .We extract the parameter from request object and assigned that value to variables defined locally and then process those variables but while processing (eg parsing the value of variable) the variable such exception rises. So please check out the value of variables before processing it.I hope this will help you to clear the bug which you face frequently...
