> 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.
