Handle exceptions when sending error message in servlet

According to Sonarqube, even though the signatures for methods in a
servlet include throws IOException, ServletException, it's a bad idea to
let such exceptions be thrown. Failure to catch exceptions in a servlet
could leave a system in a vulnerable state, possibly resulting in
denial-of-service attacks, or the exposure of sensitive information
because when a servlet throws an exception, the servlet container
typically sends debugging information back to the user.
