我在tomcat上运行时遇到此错误。我已经添加了所有必需的jar文件。所有其他实验室工作正常，但当我使用验证框架验证时，得到此错误。请帮帮我。
这是我的验证文件 - myform-validations.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts onfiguration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

这是我的配置文件-struts-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

</struts-config>
这是web.xml

这是login.jsp
<html:errors property="login.Invalid"/>
<html:form action="/loginSubmit">
<table>
<tr><td>Username</td>
<td><html:text property="username"/></td>
<td><html:errors property="username"/></td></tr>
<tr><td>Password</td>
<td><html:password property="password"/></td>
<td><html:errors property="password"/></td></tr>
<tr><td><html:submit value="Login Now"/></td></tr>
</table>
</html:form>
这是LoginForm.java
package com.jlc.struts;
import org.apache.struts.validator.ValidatorForm;
public class LoginForm extends ValidatorForm{
private static final long serialVersionUID = 1L;
private String username;
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
答案 0 :(得分：0)
验证配置文件不使用Struts配置DTD，而是：
<!DOCTYPE form-validation PUBLIC
"-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.1.3//EN"
"http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd">
当然，请使用您的Struts 1版本的实际版本。
不相关，但请缩进您的XML，JSP，Java等。如果没有它，请尝试阅读它是荒谬的。
