私のアプリケーションでは、JSTLを使用しています。しかし、Tomcatにアプリケーションをデプロイすると、以下のエラーが発生します。

私のweb.xmlには以下のエントリがあります：

<jsp-config>
    <taglib>
        <taglib-uri>http://java.sun.com/jstl/core</taglib-uri>
        <taglib-location>/WEB-INF/lib/jstl-1.2.jar</taglib-location>
    </taglib>
</jsp-config>

jspには、以下のpage/taglib宣言があります。

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%>
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>`

この例外はどのように発生し、どうすれば解決できますか？

web.xmlから以下を削除します

<taglib>
    <taglib-uri>http://java.sun.com/jstl/core</taglib-uri>
    <taglib-location>/WEB-INF/lib/jstl-1.2.jar</taglib-location>
</taglib>

サーブレット2.0仕様以降、これはもう必要ありません。また、taglib-locationは、*。tldファイルのパスを指定するために使用されます。

このエラーメッセージは、常に最初の要素の無効なXMLコンテンツが原因で発生します。たとえば、非常に小さなドット「。」XML要素の先頭にあります。

ここを参照してください
