配置文件：
<form-beans >
<form-bean name="userForm" type="com.mycar.struts.form.UserForm" />
</form-beans>

<action-mappings >
<action
attribute="userForm"
input="/register.jsp"
name="userForm"
parameter="method"
path="/user"
scope="request"
type="com.mycar.struts.action.UserAction">
<forward name="registersuccess" path="index.jsp" />
<forward name="registerfailure" path="register.jsp"/>
</action>
</action-mappings >

ActionForm 如下(省略getter和setter) ：
public class UserForm extends ActionForm {

private String user_name;
private String user_pwd;
private String user_ques;
private String user_ans;
private String user_mail;
private Integer user_sex;
private Integer user_integral;
private Integer user_grade;
private String user_realname;
private String user_rpwd;
private String checkcode;

public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if(this.user_name == null || "".equals(this.user_name)) {
errors.add("user_name",new ActionMessage("user.username.null"));
}
if(this.user_pwd == null || "".equals(this.user_pwd)) {
errors.add("user_pwd", new ActionMessage("user.userpwd.null"));
}
if(this.user_rpwd == null || "".equals(this.user_rpwd)) {
errors.add("user_rpwd", new ActionMessage("user.userpwd.null"));
} else {
if(!(this.user_pwd.equals(this.user_rpwd))) {
errors.add("user_rpwd", new ActionMessage("user.confirm.error"));
}
}
if(this.user_ques == null || "".equals(this.user_ques)) {
errors.add("user_ques", new ActionMessage("user.userques.null"));
}
if(this.user_ans == null || "".equals(this.user_ans)) {
errors.add("user_ans", new ActionMessage("user.userans.null"));
}
if(this.checkcode == null || "".equals(this.checkcode)) {
errors.add("checkcode", new ActionMessage("checkcode.null"));
}
return errors;
}
register.jsp 如下：

<body>
<html:form action="/user?method=register">
<table>
<tr><td>用户帐号:</td><td>
<html:text property="user_name"/></td><td>
<html:errors property="user_name"/></td></tr><tr><td>用户密码: </td><td>
<html:text property="user_pwd"/></td><td>
<html:errors property="user_id"/></td></tr><tr><td>确认密码： </td><td>
<html:text property="user_rpwd"/></td><td>
<html:errors property="user_rpwd"/></td></tr><tr><td>丢失密码提示问题：</td><td>
<html:text property="user_ques"/></td><td>
<html:errors property="user_ques"/></td></tr><tr><td>丢失密码问题答案：</td><td>
<html:text property="user_ans"/></td><td>
<html:errors property="user_ans"/></td></tr> <tr><td>用户邮箱:</td><td>
<html:text property="user_mail"/></td><td>
<html:errors property="user_mail"/></td></tr><tr><td>性别：</td><td>
<html:text property="user_sex"/></td><td>
<html:errors property="user_sex"/></td></tr><tr><td>真实姓名： </td><td>
<html:text property="user_realname"/></td><td>
<html:errors property="user_realname"/></td></tr><tr><td>验证码：</td><td>
<html:text property="checkcode"/></td><td><img src="image.jsp"/></td></tr><tr><td>
<html:submit value="提交"/></td><td>
<html:cancel value="重置"/></td></tr>
</table>
</html:form>
</body>
