Question

I am trying to learn Struts2. When I see the web.xml file for Struts2 in some of the sites it’s mentioned as:

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

and where as in some examples its mentioned as:

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>

Could anybody please help me? What is correct and why is it there are two approaches?

Thank you very much.

Answer 1

The FilterDispatcher (org.apache.struts2.dispatcher.FilterDispatcher) it’s deprecated since Struts 2.1.3. It’s always recommend to use StrutsPrepareAndExecuteFilter
