[求助]webwork怎样实现错误action的自动跳转

[lsqlister001]

软件环境：
xp,jdk1.4,webwork2.1.7

配置文件：
<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd">
<xwork>
<package name="main" extends="default" namespace="/main">
<default-interceptor-ref name="defaultStack"/>

<action name="login" class="loginAction">
<result name="success" type="redirect">/emp/emps.action</result>
<result name="input">/WEB-INF/main/loginValidator.jsp</result>
<interceptor-ref name="validationWorkflowStack"/>
</action>

</package>
</xwork>

错误提示信息：
com.opensymphony.xwork.config.ConfigurationException: There is no Action mapped for action name viewLogdddin,

系统是需要密码验证后才能登陆如：main/login.action,
当用户输入main/loginddd.action登陆,
需要自动跳转到main/login.action，而不是抛出异常：
com.opensymphony.xwork.config.ConfigurationException: There is no Action mapped for action name viewLogdddin,
怎样实现?
