<P>上述代码的原理为，LangSelector.jsp先实例化一个Locales对象，并把对象的Map类型的属性locales赋予下拉列表（select） 
。如此一来，下拉列表就获得可用语言的列表。大家看到LangSelector有&lt;s:form&gt;标志和一段Javascript脚本，它们的作用就是在用户在下拉列表中选择了后，提交包含“reqeust_locale”变量的表单到Action。在打开页面时，为了下拉列表的选中的当前区域，我们需要到session取得当前区域（键为“WW_TRANS_I18N_LOCALE”的属性），而该属性在没有设置语言前是为空的，所以通过值栈中locale属性来取得当前区域（用户浏览器所设置的语言）。</P>你可以把LangSelector.jsp作为一个控件使用，方法是在JSP页面中把它包含进来，代码如下所示： 

<DIV 
style="BORDER-RIGHT: #cccccc 1px solid; PADDING-RIGHT: 5px; BORDER-TOP: #cccccc 1px solid; PADDING-LEFT: 4px; FONT-SIZE: 13px; PADDING-BOTTOM: 4px; BORDER-LEFT: #cccccc 1px solid; WIDTH: 98%; WORD-BREAK: break-all; PADDING-TOP: 4px; BORDER-BOTTOM: #cccccc 1px solid; BACKGROUND-COLOR: #eeeeee"><SPAN 
style="COLOR: #0000ff">&lt;</SPAN><SPAN style="COLOR: #800000">s:include 
</SPAN><SPAN style="COLOR: #ff0000">value</SPAN><SPAN 
style="COLOR: #0000ff">="/LangSelector.jsp"</SPAN><SPAN 
style="COLOR: #ff0000"></SPAN><SPAN 
style="COLOR: #0000ff">/&gt;</SPAN></DIV><BR>在例1中的HellloWorld.jsp中&lt;body&gt;后加入上述代码，并在struts.xml中新建Action，代码如下：<BR>
<DIV 
style="BORDER-RIGHT: #cccccc 1px solid; PADDING-RIGHT: 5px; BORDER-TOP: #cccccc 1px solid; PADDING-LEFT: 4px; FONT-SIZE: 13px; PADDING-BOTTOM: 4px; BORDER-LEFT: #cccccc 1px solid; WIDTH: 98%; WORD-BREAK: break-all; PADDING-TOP: 4px; BORDER-BOTTOM: #cccccc 1px solid; BACKGROUND-COLOR: #eeeeee"><SPAN 
style="COLOR: #0000ff">&lt;</SPAN><SPAN style="COLOR: #800000">action 
</SPAN><SPAN style="COLOR: #ff0000">name</SPAN><SPAN 
style="COLOR: #0000ff">="HelloWorld"</SPAN><SPAN 
style="COLOR: #0000ff">&gt;</SPAN><SPAN style="COLOR: #000000"><BR>&nbsp; &nbsp; 
</SPAN><SPAN style="COLOR: #0000ff">&lt;</SPAN><SPAN 
style="COLOR: #800000">result</SPAN><SPAN 
style="COLOR: #0000ff">&gt;</SPAN><SPAN 
style="COLOR: #000000">/HelloWorld.jsp</SPAN><SPAN 
style="COLOR: #0000ff">&lt;/</SPAN><SPAN 
style="COLOR: #800000">result</SPAN><SPAN 
style="COLOR: #0000ff">&gt;</SPAN><SPAN style="COLOR: #000000"><BR></SPAN><SPAN 
style="COLOR: #0000ff">&lt;/</SPAN><SPAN 
style="COLOR: #800000">action</SPAN><SPAN 
style="COLOR: #0000ff">&gt;</SPAN></DIV><BR>或者，如果你多个JSP需要实现上述功能，你可以使用下面的通用配置，而不是为每一个JSP页面都新建一个Action。<BR>
<DIV 
style="BORDER-RIGHT: #cccccc 1px solid; PADDING-RIGHT: 5px; BORDER-TOP: #cccccc 1px solid; PADDING-LEFT: 4px; FONT-SIZE: 13px; PADDING-BOTTOM: 4px; BORDER-LEFT: #cccccc 1px solid; WIDTH: 98%; WORD-BREAK: break-all; PADDING-TOP: 4px; BORDER-BOTTOM: #cccccc 1px solid; BACKGROUND-COLOR: #eeeeee"><SPAN 
style="COLOR: #0000ff">&lt;</SPAN><SPAN style="COLOR: #800000">action 
</SPAN><SPAN style="COLOR: #ff0000">name</SPAN><SPAN 
style="COLOR: #0000ff">="*"</SPAN><SPAN style="COLOR: #0000ff">&gt;</SPAN><SPAN 
style="COLOR: #000000"><BR>&nbsp; &nbsp; </SPAN><SPAN
