JSP taglib 指令错误
我在 weblogic 中部署时收到以下错误：
解析JSP文件'/pages/RegisteredEmployee.jsp'失败：/pages/RegisteredEmployee.jsp(5)：使用标签库uri='/WEB-INF/struts-html.tld' prefix='html时出错': Tag 类 'org.apache.struts.taglib.html.FormTag' 没有与 TLD 声明的属性 'name' 对应的 setter 方法，（JSP 1.1 规范，5.4.1）可能由于 /pages/ 中的错误而发生RegisteredEmployee.jsp 第 5 行：
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
我的 struts-html.tld位于 /WEB-INF 文件夹内。我还尝试将标签库指令路径更改为http://jakarta.apache.org/struts/tags-html，它显示了相同的错误。我还将 struts-html.tld 复制到 /WEB-INF/lib 中，它显示了相同的错误。
我该如何解决这个问题？

I receive the following error while deploying in weblogic:
Parsing of JSP File '/pages/RegisteredEmployee.jsp' failed: /pages/RegisteredEmployee.jsp(5): Error in using tag library uri='/WEB-INF/struts-html.tld' prefix='html': The Tag class 'org.apache.struts.taglib.html.FormTag' has no setter method corresponding to TLD declared attribute 'name', (JSP 1.1 spec, 5.4.1) probably occurred due to an error in /pages/RegisteredEmployee.jsp line 5:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
My struts-html.tld is inside /WEB-INF folder. I also tried to change the tag lib directive path to http://jakarta.apache.org/struts/tags-html, it displayed same error. I also copied struts-html.tld into /WEB-INF/lib, it displayed same error.
How can I solve this problem?

问题可以在这里找到：
我已经好几个月没有使用 Struts 了，但它在
value="..."上抱怨。相反，value。The problem can be found here:
I haven't done Struts in months, but it's complaining on
value="...". Rather do this,There's (probably) no attribute
valueon<html:submit>.
