500 Servlet Exception
I am creating a standard dynamic web project including a Servlet, a filter to filter the request and jsp pages. I am taking the number of books from the welcome.jsp and depending on the count I am populating the input boxes on the add.jsp. I want to filter the data coming through the add.jsp. When I verify data through Regex, its showing me error. Also is my flow correct i.e. from the start FILTER --> CONTROLLER --> FILTER --> PAGE and so on???

Therefore, whatever your Servlet is doing, make sure you have handled exceptions and the libraries are properly configured.
