分析：查看nutch Web应用根目录下的search.jsp可知，是引号匹配的问题。

<jsp:include page="<%= language + "/include/header.html"%>"/> //line 152 search.jsp

第一个引号和后面第一个出现的引号进行匹配，而不是和这一行最后一个引号进行匹配，所以问题就出现了。

解决方法：

将该行代码修改为：<jsp:include page="<%= language+urlsuffix %>"/>

这里我们定一个字符串urlsuffix，我们把它定义在language字符串定义之后，

String language =   // line 116 search.jsp
    ResourceBundle.getBundle("org.nutch.jsp.search", request.getLocale())
    .getLocale().getLanguage();
String urlsuffix="/include/header.html";

修改完成后，为确保修改成功，重启一下Tomcat服务器，进行搜索，不再报错。
