> We have an Action class named 'Index' immediately under com.example.common.action and
is annotated @ParentPackage('default') which is declared in package directive in struts.xml
and has "/" for its namespace and extends "struts-default". It also declares @Result so that
it responses with jsp files corresponding the string values returned by its execute() method.
> In our struts.xml, the following struts setting is configured along with other necessary
configurations that are needed for convention-plugin.
>     <constant name="struts.action.extension" value=","/>
> When accessing /my_context/none_existing_path, the request apparently hits this Index
class and the contents of the jsp declared in the Index's @Result section gets returned.
> However, if we provide /my_context/, we receive the following error:
> HTTP Status 404-There is no Action mapped for namespace[/] and action name [] associated
with context path [/my_context].
> We want to know the reason why accessing /my_context/none_existing_path, where none_existing_path
has no matching action, can fallback to Index class, but error is returned when when the URL
requested is just /my_context/.
> Currently, our convention-plugin settings are declared as follows:
>     <constant name="struts.convention.package.locators.basePackage" value="com.example"/>
>     <constant name="struts.convention.package.locators" value="action"/>
> Strangely, if we changed the value of the struts.convention.package.locators.basePackage
to
> com.example.common and narrowed the search scope of the aforementioned Index file, requesting
/my_context/ displayed the content of the jsps declared in @Result section of the Index class.
However, as our action classes are distributed throughout the com.example.[a-z].action packages,
where [a-z] represents the large volume of directories we have in our package structure, we
cannot use this trick as a workaround. We have also tried placing index.jsp at the top level
of the class path, and have the index.jsp redirect to /my_context/index, which worked but
not what we want. Could this be a bug?
> We appreciate your responses. 
> Thank you in advance.
