p.s
关键在于struts.xml中
<constant name="struts.custom.i18n.resources" value="mess"/>
和mess_en_US.properties 与 mess_zh_CN.properties
jsp调用properties数据
<jsp:useBean id="d" class="java.util.Date" scope="page"/>
<s:text name="welcomeMsg">
<s:param>${d} </s:param>
</s:text>
或
<s:textfield name="user.username" key="username" value="testuser"/>
中的key即代表properties中的键
在Action中调用properties中的键值使用getText("properties中的键")，详见UserLoginAction中的login()
