I can find an explanation to your problem of having a NullPointer, but not the
reason of only getting it after some days working... Having the NullPointer is
because when you use:
!request.getParameter("text").equals("capturados") the parameter is null. You
can change all of this statements for one of the kind
"capturados".equals(request.getParameter("text")) which will never fail,
because "capturados" is never null. Getting this parameter as null is maybe due
to having a servlet or something between the call to this JSP and then
forwarding to it. Hope it helps someway... Is the previuos form page directed
to a servlet (or some framework) and then forwarded to this page? If that's the
case, the problem is probably in this intermediate phase.
