      Description

      In Struts 2.1.2 I attempted to break struts.xml into multiple files becuase it was getting too big.

      Starting here: http://struts.apache.org/2.x/docs/can-we-break-up-a-large-strutsxml-file-into-smaller-pieces.html

      Specifically from that page:
      "You can use <include> elements in your struts.xml interchangeably with <package> elements. The configuration objects will be loaded in the order of appearance. The framework reads the configuration from top to bottom and adds objects as they are referenced."

      Following the note above I added an included file after my base package (where some interceptor stacks are defined).

      For example (new copy of struts.xml):

      <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
      "http://struts.apache.org/dtds/struts-2.0.dtd">
      <struts>
      <package name="baseEAP" extends="struts-default" abstract="true">
      <interceptors>
      <interceptor name="DataPrep" class="xx" />

      <interceptor-stack name="dataPrepStack">
      <interceptor-ref name="defaultStack"/>
      <interceptor-ref name="DataPrep"/>
      </interceptor-stack>
      </interceptors>
      </package>

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

      ....(lots of packages that extend baseEAP)...

      </struts>

      All other packages extend baseEAP, and some actions reference the interceptor stack dataPrepStack – it works great.
      I pulled one of those working packages out of struts.xml and placed it in its own file. The code above shows where <include file...> was inserted below the baseEAP package declaration. No other changes were made.

      In the separate file (struts-ajax.xml) the package signature is exactly the same as it was in struts.xml:
      <!DOCTYPE struts PUBLIC
      "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
      "http://struts.apache.org/dtds/struts-2.0.dtd">
      <struts>
      <package name="ajax" extends="baseEAP,gwt-default">
      <action name="ajaxManageMenus" class="xx">
      <interceptor-ref name="dataPrepStack" />
      <interceptor-ref name="gwt"/>
      </action>
      </package>
      </struts>

      Unfortunately the xml files would not load upon deployment:
