You must set this options in struts.xml according to the documentation:
<constant name="struts.enable.SlashesInActionNames" value="true"/>
<constant name="struts.mapper.alwaysSelectFullNamespace" value="false"/>
and probably remove the .do
extension, by setting it to empty (or better to comma, to prevent Struts handling static resources as namespaces):
<constant name="struts.action.extension" value=","/>
Otherwise, you can switch to Advanced Wildcards by using regex Pattern Matcher.
