我的jsp中的错误taglib [英] Error taglib in my jsp
问题描述
我有一个使用Maven和Struts 1.3.10的项目.
我在Pom.xml中的依赖项:
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>

</dependency>

我的JSP中有错误
JSP示例:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%@taglib uri="http://struts.apache.org/tags-html-el" prefix="html" %>
<%@taglib uri="http://struts.apache.org/tags-logic-el" prefix="logic" %>
<%@taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
<%@taglib uri="http://struts.apache.org/tags-bean-el" prefix="beanEl" %>
<%@taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<%@taglib uri="http://fckeditor.net/tags-fckeditor" prefix="fck" %>
<%@taglib tagdir="/WEB-INF/tags/" prefix="customTag" %>
<!-- Importation du CSS pour le widget Dialog -->
<link rel="stylesheet" type="text/css" href="<html:rewrite page="/css/yui/container.css" />"></link>
<!-- Importation du CSS pour le widget Calendar -->
<link rel="stylesheet" type="text/css" href="<html:rewrite page="/css/yui/calendar.css" />"></link>
问题是，与我的taglib相比，我充满了很多错误
找不到用于的标记库描述符 " http://struts.apache.org/tags-html-el "
找不到用于的标记库描述符 " http://struts.apache.org/tags-logic-el "
等，等等...
为什么错了
由于在当今的服务器环境中通常不需要EL标签，因此将它们单独捆绑在一起. (他们也曾经在这里，但是出于不同的原因.)
http://mvnrepository.com/artifact/org. apache.struts/struts-el/1.3.10
➜ struts jar tf struts-el-1.3.10.jar | grep tld

I have errors in my JSP,
Example of JSP:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%@taglib uri="http://struts.apache.org/tags-html-el" prefix="html" %>
<%@taglib uri="http://struts.apache.org/tags-logic-el" prefix="logic" %>
<%@taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
<%@taglib uri="http://struts.apache.org/tags-bean-el" prefix="beanEl" %>
<%@taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<%@taglib uri="http://fckeditor.net/tags-fckeditor" prefix="fck" %>
<%@taglib tagdir="/WEB-INF/tags/" prefix="customTag" %>
<!-- Importation du CSS pour le widget Dialog -->
<link rel="stylesheet" type="text/css" href="<html:rewrite page="/css/yui/container.css" />"></link>
<!-- Importation du CSS pour le widget Calendar -->
<link rel="stylesheet" type="text/css" href="<html:rewrite page="/css/yui/calendar.css" />"></link>
The problem is i have full of errors compared my taglib
Can not find the tag library descriptor for "http://struts.apache.org/tags-html-el"
Can not find the tag library descriptor for "http://struts.apache.org/tags-logic-el"
etc, etc...
why it's wrong
Since the EL tags are generally unnecessary in today's server environments they're bundled separately. (They were before, too, but for different reasons.)
http://mvnrepository.com/artifact/org.apache.struts/struts-el/1.3.10
➜ struts jar tf struts-el-1.3.10.jar | grep tld
META-INF/tld/
META-INF/tld/struts-bean-el.tld
META-INF/tld/struts-html-el.tld
META-INF/tld/struts-logic-el.tld
META-INF/tld/struts-tiles-el.tld
