显然，org.apache.struts.action.ActionServlet中的Servlet名称“Action”存在问题。 Unfurtunatley我不知道我做错了什么。你有个主意吗？许多事先提前。奥利

Answer 1

发生此错误是因为您的servlet-core jar不在您的运行时类路径中。如果您使用的是maven，

打开您的EAR /网络项目属性
点击＆＃34;部署程序集＆＃34;
点击＆＃34;添加...＆＃34;
选择＆＃34; Java构建路径条目＆＃34;
点击＆＃34;下一步＆＃34;
选择＆＃34; Maven Dependencies＆＃34;
点击＆＃34;完成＆＃34;

如果不是maven，请确保您放置罐子的lib文件夹位于＆＃34;部署装配＆＃34;。

Answer 2

我认为您应该将jar文件保存到/ WEB_INF / Lib文件夹中，这对您有用。

Answer 3

使用Tomcat 7时出现了同样的错误。我找到了解决方案。根本原因是struts jar版本或jar配置。 Previsouly我使用struts.jar，现在我添加了struts-core-1.3.10.jar推荐用于Tomcat 7和servlet-api jar shloud可用并确保jar配置正确或不正确..它更好地删除当前项目和刚刚开始。

Answer 4

我认为问题是由于jar文件，请确保lib文件夹中的jar文件。如果您使用的是eclipse，则将所有jar文件复制到lib文件夹而不是构建路径

Answer 5

我遇到了同样的问题。虽然我将struts库添加到项目Build Path并标记为导出，但Eclipse在WEB-INF / lib中没有包含任何内容。与Vivek Kothari所说的类似，你可以让Eclipse添加它们。但是，如果您已经下载了jar文件并添加到项目构建路径（可能是用户库），则可以在步骤6中选择您的库。

Answer 6

此问题是由于仅丢失Jars ... 将所有这些罐子放入/ WEB-INF / lib文件夹...

ANTLR-2.7.2.jar
公地BeanUtils的-1.8.0.jar
公地链1.2.jar
公地消化器-1.8.jar
共享记录-1.0.4.jar
公地验证-1.3.1.jar
口 - 2.0.8.jar
支柱核-1.3.10.jar
支柱-标签库-1.3.10.jar

如果我们只使用struts-core.jar，那么我们就会遇到这个问题...因为所有其他的jar也是必需的。

Answer 7

为了避免这种类型的问题，将所有struts jar放在web app的lib文件夹中。这将解决问题

Answer 8

org.apache.struts.actions.ActionServlet not org.apache.struts.action.ActionServlet

Answer 9

我们需要添加一个额外的jar：struts-extras-1.3.9.jar中的WEB/lib。正确地说是org.apache.struts.actions.ForwardAction

java.lang.ClassNotFoundException：org.apache.struts.action.ActionServlet
