Struts2表单提交正常，但后台有异常

a_a\\\ 2013-04-24 09:38:49

大概的主要内容：
这是index.jsp页面



<form name="form" method="post">

User<s:textfield name="username"/><br/> 

Password<s:password name="password"/><br/>

 <input type="submit" name="submit1" value="submit1" onclick="document.form.action='struts/login1!add';document.form.submit();">

</form>

这是struts.xml页面



<package name="default" namespace="/struts" extends="struts-default">

         

        <global-results>

            <result name="error">/error.jsp</result>

        </global-results>

         

        <global-exception-mappings>

            <exception-mapping exception="java.lang.Exception" result="error"/>

        </global-exception-mappings>



        <action name="login*" class="actionClass.LoginAction{1}" >

            <result >         

              /Success.jsp

            </result>

        </action>

  

        

    </package>

这是action类



package actionClass;



import java.util.Map;



import com.opensymphony.xwork2.ActionContext;

import com.opensymphony.xwork2.ActionSupport;



public class LoginAction1 extends ActionSupport {

	

	private Map request;

	private Map session ;

	private Map application;

	

	private String username;

	private String password;

	

	public LoginAction1( ){

		request = (Map) ActionContext.getContext().get("request");

		session = ActionContext.getContext().getSession();

		application = ActionContext.getContext().getApplication();

	}

	

	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;

	}

	

	public Map getRequest() {

		return request;

	}

	public void setRequest(Map request) {

		this.request = request;

	}

	public Map getSession() {

		return session;

	}

	public void setSession(Map session) {

		this.session = session;

	}

	public Map getApplication() {

		return application;

	}

	public void setApplication(Map application) {

		this.application = application;

	}

	

	public String add() {

		request.put("hiphop1","DJ");

		session.put("hiphop2", "MC");

		application.put("hiphop3", "Bboy");

		System.out.println(username);

		System.out.println(password);

		return SUCCESS;

	}





}

提交成功后的页面



 <body> 

      struts2:<s:property  value="#request.hiphop1"/> | jsp:<%= request.getAttribute("hiphop1") %><br>  

      struts2:<s:property  value="#session.hiphop2"/> | jsp:<%= session.getAttribute("hiphop2") %><br> 

      struts2:<s:property  value="#application.hiphop3"/> | jsp:<%= application.getAttribute("hiphop3") %><br>

      <s:property value="#attr.hiphop2"/>  

      <s:debug></s:debug>

  </body>

整个程序可以运行,form的参数也能接收到。但是后台异常了，我看不懂是什么回事，但是程序正常运行了。
一下是错误代码！求助各位高手,感谢
