I am facing a problem that I couldn\'t find a key word for googleing the following situation:
Set the alwaysSelectFullNamespace property to true.
From struts-default.properties:
### Whether to always select the namespace to be everything before the last slash or not
struts.mapper.alwaysSelectFullNamespace=true
XML configuration is preferred, so in your struts.xml:
<struts>
<constant name="struts.mapper.alwaysSelectFullNamespace" value="true" />
...
