Java library to map HTTP status code to descriptio

Question

I'm in the situation where I'm writing custom error pages for a webapp (primarily to reduce information disclosure from the servlet container's default error pages). Since I need an error page for each error status code, I'm going to have to have a sensible response for each code. As far as I can tell, these error pages don't have to be particularly user-friendly, but simply redirecting everything to a single "it went wrong" error page is going to make diagnosing problems very difficult.

So I'm wondering if there is a Java library that provides a good mapping between HTTP status codes and a brief human-readable description of them (ideally a 2-4 word "summary", for use as a page title, as well as a 1-3 sentence message expanding on the summary). Then I could just use this in a JSP to provide some feedback on the class of the error. If not I'm sure I can write one myself, but if wheels have been invented I'm happy to use them.

Latest apache http components v4+ ( httpCoponents )

Introduces the following: HttpStatus as an enum containing all of the httpStatuses

For their description use: EnglishReasonPhraseCatalog.INSTANCE.getReason(code, Locale.ENGLISH);

Where your status code == code, eg: 200

For example:

HttpStatus.SC_FORBIDDEN == 403
EnglishReasonPhraseCatalog.INSTANCE.getReason(403, Locale.ENGLISH) == "Forbidden"
