请帮我看看这个webwork的异常！！
bean:
package MyTest;
import java.util.*;
public class LoginInfo {
private String password;
private String username;
private List messages = new ArrayList();
private String errorMessage;
public List getMessages() {
return messages;
}
public String getErrorMessage() {
return errorMessage;
}
public void setErrorMessage(String errorMessage) {
this.errorMessage = errorMessage;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
action:
package MyTest;
import java.util.Map;
import com.opensymphony.xwork.Action;
import com.opensymphony.xwork.ActionContext;
import com.opensymphony.xwork.ModelDriven;
public class LoginAction implements Action,ModelDriven{
private final static String LOGIN_FAIL="loginfail";
LoginInfo loginInfo = new LoginInfo();
public String execute() throws Exception {
if ("erica".equalsIgnoreCase(loginInfo.getUsername())
&& "mypass".equals(loginInfo.getPassword())) {
//将当前登录的用户名保存到Session
ActionContext ctx = ActionContext.getContext();
Map session = ctx.getSession();
session.put("username",loginInfo.getUsername());
//出于演示目的，通过硬编码增加通知消息以供显示
loginInfo.getMessages().add("message1");
loginInfo.getMessages().add("message2");
loginInfo.getMessages().add("message3");
return SUCCESS;
}else{
loginInfo.setErrorMessage("Username/Password Error!");
return LOGIN_FAIL;
}
}
public Object getModel() {
return loginInfo;
}
}
