因为/TestStruts是部署应用程序的上下文路径。它与包中的名称空间具有相同的路径。尝试
http://localhost:8080/TestStruts/TestStruts/test.action
当URls从struts标记渲染时，它正在尝试查找相应的动作配置。如果找不到配置，则发出警告。
解决方法我正在NetBeans 7.2.1的struts 2.3.16上尝试我的第一个应用程序。输入URL时显示以下错误-http://localhost:8080/TestStruts/Test.action（有一个Test.jsp页面）。

该Test.jsp页面：
<s:form namespace='/TestStruts' action='test'> <table border='0' class=''> <tr><td> <s:textfield name='name' label='Enter your name'/></td> </tr> <tr><td> <s:textfield name='email' label='Enter your email'/></td> </tr> <tr><td></td><td><s:submit value='Submit'/></td> </tr> </table></s:form>
动作类：
package actions;import com.opensymphony.xwork2.ActionSupport;public final class TestAction extends ActionSupport{ private static final String SUCCESS = 'success'; private String name; private String email; public String getName() {return name; } public void setName(String name) {this.name = name; } public String getEmail() {return email; } public void setEmail(String email) {this.email = email; } @Override public String execute() throws Exception {System.out.println('name = '+name);System.out.println('email = '+email);return SUCCESS; }}

除了Spring的jar文件外，我还添加了以下jar文件到类路径中。

我想念什么？
