Document

Expose the Servlet spec's error attributes as javax.servlet.http.HttpServletRequest attributes under the keys defined in the Servlet 2.3 specification, for error pages that are rendered directly rather than through the Servlet container's error page resolution: javax.servlet.error.status_code , javax.servlet.error.exception_type , javax.servlet.error.message , javax.servlet.error.exception , javax.servlet.error.request_uri , javax.servlet.error.servlet_name .
