1. 在web.xml不认<taglib>解决办法:
如果是头是这样的<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
直接在后面加
<taglib>
<taglib-uri>/WEB-INF/struts-logic.tld</taglib-uri>
<taglib-location>/WEB-INF/struts-logic.tld</taglib-location>
</taglib>
如果头是这样的
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
在后面加
<jsp-config>
<taglib>
<taglib-uri>/WEB-INF/validator-user.tld</taglib-uri>
<taglib-location>/WEB-INF/validator-user.tld</taglib-location>
</taglib>
</jsp-config>
