struts2国际化，不经过action的jsp页面如何国际化

[licip]

struts2中项目中的国际化切换是通过设置session中WW_TRANS_I18N_LOCALE值来设定的，因为根据浏览器的语言不能满足需求，还需要可以手动切换。
现在的问题是：某些的jsp页面是直接调用的，不经过struts2的action，这时的国际化就出问题，是浏览器的语言，而不是用户设置的。

各位有什么好的方法解决这个呢？

自己重写一个I18n的标签，设置Locale不就行了？

这是一种方式，但不是我想要的那种。看来是必须改原码[Quote=引用 1 楼 fainfy 的回复:]
Java code

为什么要改源码？
你自己扩展一个属于你的I18n标签就行了。
也可以在过滤器里面把ActionContext修改成，Session里面的Locale。这个方式我认识不是一个很好的解决方式，因为可能会引发一些其它不便的问题。

用jstl标签库呗，很好用的
