Actually in my servlet i am reading devices from a file.
But when FileNotFoundException occurs i need to see that exception in the jsp page.
how can i show the exception message in jsp?
could any body suggest?
You can map an error handling page in the deployment descriptor.
But be aware that showing exceptions to uses is generally considered a bad practice. Rather, it is more customary to log the exceptions for the developers, and to show the users a more generic "sorry, but something went wrong" message.
