Subject [jira] Commented: (MYFACES-3055) META-INF/faces-config.xml files in JARs are loaded twice
Date Tue, 22 Feb 2011 23:24:38 GMT

    [ https://issues.apache.org/jira/browse/MYFACES-3055?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12998096#comment-12998096
] 

Mike Kienenberger commented on MYFACES-3055:
--------------------------------------------

In the case of jetty/eclipse, it was a bug in the classloading which would return the same
resource twice.
I think it was caused by a call to loader.getResources(*), but I don't remember exactly. 
I wonder if the same method is being called in your situation?

For eclipselink, I worked around the problem by ignoring the second duplicate result.

> However, /WEB-INF/faces-config.xml in the war is only loaded once, so I suspect that
this is a bug with org.apache.myfaces.config.DefaultFacesConfigurationProvider. My current
workaround to install OpenFaces is, therefore, extract META-INF/faces-config.xml out of the
jar, and load it with the war.
