[jira] Commented: (WW-1635) struts.xml include dependant packages
not loading properly
[ https://issues.apache.org/struts/browse/WW-1635?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_40211 ]
Sebastien Poirier commented on WW-1635:
---------------------------------------
Is it possible to reopen this issue: I upgraded recently from struts-2.0.1 to 2.0.5 and got exactly the same problem as Matt.
I spent a few time looking for the problem and it happened that the problem occurs in xwork2 when loading the configuration files:
in class com.opensymphony.xwork2.config.providers.XmlConfigurationProvider, the method loadConfigurationFiles() was modified in the recent releases of xwork (since 2.0.0 I think): now when a struts.xml file includes another struts-foo.xml file, the packages are read in th wrong order, the ones from struts-foo.xml being configured before the ones in struts.xml, that's why the configuration provider can't resolve the parent package.
I found a simple patch to force the configuration provider to read the includes in the right order, but it applies to xwork, don't know if you work in collaboration with them.
I deployed my application with the patched version of xwork, and works perfectly now.
begin patch for com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.java ------------------------------------------------------------

end patch ----------------------------------------------------------------
