As you know, both doGet and doPost from HTTPServlet throw ServletException and IOException. I created a class that extends HttpServlet and overrides doGet and doPost method, but I need these methods to throw SQLException in addition to ServletException and IOException. I understand that the concept of "overriding" includes overriding exceptions to be thrown, but is there any way I can throw SQLException from doGet and doPost?

Your overridden methods must comply with the contract defined by HttpServlet methods. You cannot declare any checked exceptions in the throws clause of your methods other than HttpServletException, IOException or their subclasses.

Thus the only ways to throw your SQL exception are:

1. Wrap it as a cause into an HttpServletException or IOException and throw one of them.
2. Wrap it as a cause of a RuntimeException and throw it.
3. Throw an SQLException where you want to but catch it and either handle or rethrow as in pp. 1 or 2.
