which filter class to choose inside <filter-class> tag in struts2

I have one small doubt.. In Struts2, inside web.xml of tag, we will choose some filter name. While searching in examples, I have came across with 2 types开发者_运维问答 of filters using inside that tag.. They are

1. org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
2. org.apache.struts2.dispatcher.FilterDispatcher

So, now Im in a confusion which one to use in what condition?? Waiting for your replies..
