Answer 1

You must set the following property in the struts.xml :

<constant name="struts.action.extension" value=","/>

You can set different extensions, or no extension at all, that is specified with the comma for a reason, as you can read in this answer.

It's generally used together with Advanced Wildcard Mappings,to create user-friendly pretty URLs.
