Why you should care
Exception handling is the process in JSP to handle runtime errors. Any number of exceptions can arise when JSP page is executed. Without defining or declaring the errors, the error is not undeclared and is left unverified causing it have security risks and flawed resiliency which is not ideal for the code.
It is recommended to declare an error page so that the code has fewer security risks which boosts code resiliency.
How we detect
Lengthy stack traces are not aesthetically pleasing and can increase security risks by exposing information that does not need to be released. JSPs allow developers to catch and handle exceptions in the code, resulting in more secure and aesthetically pleasing exception handling.
