程序下载地址：http://www.kissjava.com/kissjava.rar

此程序是这样子的。

User.java 是用户类
UserForm.java继承 ActionForm .
AddUserAction.java 继承了 Action .
UserBean.java 处理业务，即添加用户到数据库中。
CreateUser.jsp 添加用户的页面
UserCreated.jsp 查看刚刚添加的用户的页面

struts-config.xml 的内容

<?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>
<form-beans>
<form-bean name="userForm" type="kissjava.UserForm" />
<form-bean name="formBean" type="javax.servlet.http.HttpServletRequest" />
</form-beans>
<global-forwards>
<forward name="userCreated" path="/userCreated.jsp" />
<forward name="error" path="/error.jsp" />

<action name="userForm" path="/createUser" type="kissjava.AddUserAction" validate="true" input="/createUser.jsp" scope="request" />
</action-mappings>
<message-resources parameter="ApplicationResources" />
</struts-config>

AddUserAction.java 内容：

package kissjava;

import org.apache.struts.action.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public final class AddUserAction extends Action{
public ActionForward execute(ActionMapping mapping,ActionForm form,HttpServletRequest request,
HttpServletResponse response)
throws Exception
{
//UserBean Control
UserBean userBean = new UserBean();
UserForm userForm = new UserForm();
User user = new User();
user = userForm.getUser();
try{
userBean.addUser(user);
ActionMessages messages = new ActionMessages();
ActionMessage message = new ActionMessage("message.user.insert.success",user.getName());
messages.add(ActionMessages.GLOBAL_MESSAGE,message);
saveMessages(request,messages);
//put the result in request,to let the next page get this value
request.setAttribute("user",user);
return(mapping.findForward("userCreated"));
}
catch(Exception de){
ActionErrors errors = new ActionErrors();
ActionError error = new ActionError("error.user.databaseException");
errors.add(ActionErrors.GLOBAL_ERROR,error);
saveErrors(request,errors);
return(mapping.findForward("error"));
}
}
}

CreateUser.jsp

</body>
</html:html>

附：数据库 table user
CREATE TABLE user (
id tinyint(10) unsigned NOT NULL auto_increment,
name char(20) default '0',
password char(20) default '0',
email char(20) default '0',
joindate char(20) default '0',
PRIMARY KEY (id)
) TYPE=MyISAM;

现在，程序在 createuser.jsp 提交数据后,总是跑到error.jsp，为什么呢？求救啊！
