struts的taglib加载问题 狂撒分!!!!

Question

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
这个东西我都是这样写的<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
这不行了嘛!
我用的eclipse

Answer 1

我把它给成了<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%> 我是在每个页面上加载的,不是在web.xml上配置的!错误如下:HTTP Status 500 - --------------------------------------------------------------------------------type Exception reportmessage description The server encountered an internal error () that prevented it from fulfilling this request.exception org.apache.jasper.JasperException: Unable to load class for JSP

Answer 2

web.xml里面加上
<taglib>
<taglib-uri>/tags/struts-bean</taglib-uri>
<taglib-location>/WEB-INF/struts-bean.tld</taglib-location>
</taglib> <taglib>
<taglib-uri>/tags/struts-html</taglib-uri>
<taglib-location>/WEB-INF/struts-html.tld</taglib-location>
</taglib> <taglib>
<taglib-uri>/tags/struts-logic</taglib-uri>
<taglib-location>/WEB-INF/struts-logic.tld</taglib-location>
</taglib> <taglib>
<taglib-uri>/tags/struts-nested</taglib-uri>
<taglib-location>/WEB-INF/struts-nested.tld</taglib-location>
</taglib> <taglib>
<taglib-uri>/tags/struts-tiles</taglib-uri>
<taglib-location>/WEB-INF/struts-tiles.tld</taglib-location>
</taglib>

Answer 3

<%@taglib uri="WEB-INF/struts-bean.tld" prefix="bean"%>
<%@taglib uri="WEB-INF/struts-html.tld" prefix="html"%>
<%@taglib uri="WEB-INF/struts-logic.tld"prefix="logic"%>这里是jsp里面写的

Answer 4

记得把struts-bean.tld....这些文件放到web-inf目录下

Answer 5

你既然在WEB.XML文件中已经加载了如这样的标记
<taglib>
<taglib-uri>/tags/struts-bean</taglib-uri>
<taglib-location>/WEB-INF/struts-bean.tld</taglib-location>
</taglib>那在jsp的页面上就应该是这样写才对呀!
<%@taglib uri="/tags/struts-bean" prefix="bean"%>我想问问是不是这样的原因
struts-config.xml文件的dtd应用是
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">我选用的是struts1.2的 不知道是不是这样?

Answer 6

还有,你的.taglib.jar都放到lib目录下了?

Answer 7

我是这样设置的
把所有的.tld文件都放在WEB-INF文件下
然后这样描述::::
<%@ taglib uri="/tags/struts-bean" prefix="bean"%>在web.xml里这样设置
  <jsp-config>
        <taglib>
                <taglib-uri>/tags/struts-bean</taglib-uri>
                <taglib-location>/WEB-INF/struts-bean.tld</taglib-location>
        </taglib>
 </jsp-config>

Answer 8

我按照 laitaogood 的方法做了一下,还是没有用!我用的是MYECLIPSE 5.1.1的版本.之后我仔细研究了一下,我找的MYECLIPSE 5.1的安装目录,发现其实他提供的STURTS只有1.0和1.2的版本而已
  比如在某个JSP有个<html:html lang="true">(我是选用1.2的版本的),但是在他的WEB-INF/lib的struts-html.tld的文件中根本就没有lang 的属性.只有local这个属性而已,而这个属性只在1.2以前的版本中有,所以肯定有点的是MYECLIPSE说提供1.2版本的开发是假的
  我真的不知道各位是怎么做出来的!重申一遍,我用的是struts1.2!!!!!

Answer 9

<%@taglib uri="WEB-INF/struts-bean.tld" prefix="bean"%>
<%@taglib uri="WEB-INF/struts-html.tld" prefix="html"%>
<%@taglib uri="WEB-INF/struts-logic.tld"prefix="logic"%>
这种写法很明显错误了.<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
这样试试,我试过没问题
