struts.xml includes not loading in order, or not loading parent
---------------------------------------------------------------
Key: WW-2745
URL: https://issues.apache.org/struts/browse/WW-2745
Project: Struts 2
Issue Type: Bug
Components: XML Configuration
Affects Versions: 2.1.2
Environment: Struts 2.1.2, Weblogic 10
Reporter: Becky O'Sullivan
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:
