A,D Correct answer
Explanation

Error-page configuration supports two formats: using error-code for HTTP status codes (option A) OR using exception-type for Java exceptions (option D). Both require a location element pointing to the error page. Options B and C incorrectly mix both error-code and exception-type in the same error-page element - only one should be specified per error-page entry.
