HttpStatus JSP Tag Library

A simple JSP Tag Library to display the code, reason and/or cause for HTTP status codes in JSP error pages.

For example:

<%@ page isErrorPage="true" %>
<%@ taglib prefix="hs" uri="http://erik.thauvin.net/taglibs/httpstatus" %>
<html><head>
<title><hs:code/> <hs:reason default="Server Error"/></title>
</head>
<h1><hs:reason default="Server Error"/></h1>
Cause: <pre><hs:cause default="Unable to complete your request."/></pre>
...

<%@ page isErrorPage="true" import="net.thauvin.erik.httpstatus.Reasons" %>
<%= Reasons.getReasonPhrase(pageContext.getErrorData().getStatusCode()) %>

would display on a 501 status code:

Not Implemented

hs:cause

The <hs:cause/> tag displays the cause of current HTTP status code, if any. A shorthand for:

<%= pageContext.getErrorData().getThrowable().getCause().getLocalizedMessage() %>

Optional attributes are:

Attribute	Description
`default`	The fallback value to output, if no cause is available.
`escapeXml`	Converts <, >, &, ', " to their corresponding entity codes. Value is `true` by default.

hs:code

The <hs:code/> tag displays the current HTTP status code, if any. A shorthand for:

<%= pageContext.getErrorData().getStatusCode() %>

hs:reason

The <hs:reason/> tag displays the reason for a HTTP status code, if any. Optional attributes are:

Attribute	Description
`code`	The HTTP status error code. If not specified the current status code is used.
`default`	The fallback value to output, if no reason is available.
`escapeXml`	Converts <, >, &, ', " to their corresponding entity codes. Value is `true` by default.

The reasons are defined in a ResourceBundle properties as follows:
