Null Pointer Exception

String x="";
Vector From = (Vector)session.getAttribute("DATESFROM");
int isize = From.size();
Vector To = (Vector)session.getAttribute("DATESTO");
int isize2 = To.size();
System.out.println(".........2");


I am getting null pointer exception in int isize = From.size();

That's because there's no attribute in your session called "DATESFROM" at that point. Either the name is not matching or the code for setting the object failed to set a non null value or failed to execute at all.
