This is puzzling me. This happens be in a servlet that I modified. In
the code if a user tries to upload a file that is larger than the max
file size that is set in the servlet it throws an IO Exception. The
problem is in the catch I can't seem to redirect the user to a new
page (or print to the screen for that matter). Regardless of whether
I have the redirect in the catch or not, the user is simply returned
with your typical browser "Page not found" error. This is puzzling me
because the System.out.println is being reached in the catch, yet I
can do a redirect in the catch nor print to the screen, etc. Any
ideas what is causing the page to display the "page not found" error
and not handle a redirect in the catch block at the end???
Thank you for any help.
