Question

I have multiple XML configs.

struts.xml

<struts>
  <include file="struts-user.xml" />

  <package name="baseInterceptors" extends="struts-default">
    <interceptor name="...">
       ...
    </interceptor>
       ...
  </package>

  <package name="default" extends="struts-default,baseInterceptors">
    <action name="...">
       ...
    </action >
       ...
  </package>
</struts>

struts-user.xml

<struts>
  <package name="user" extends="struts-default,baseInterceptors">
    <action name="...">
       ...
    </action >
    ...
  </package>
</struts>

But the interceptors from baseInterceptors are not available in struts-user.xml. How can I solve this problem?

Answer 1

Configuration files are processed in order: The <include> is processed before the baseInterceptors and default packages are processed (read: defined).

In other words, the included file depends on pacakges that are not yet defined.

The package configuration docs explain this in a note near the top with an exclamation point next to it.

Unrelated, but you’ve duplicated some configuration, which is misleading/uncommunicative: baseInterceptors already extends struts-default, so there’s no need to extend both. Consider creating something like an application-default package so it’s obvious everything in the app should extend from it. This eliminates unnecessary duplication and communicates your intent.
