starting in Alfresco 5.0, the configurations files that you could previously find exploded in the alfresco/WEB-INF/classes directory are now contained in the JAR of that module, e.g. the vti-context.xml should be contained by the alfresco-vti-5.0.b.jar
Thank you for the reply and answer! I'm currently have been looking for the jar file that you referenced. Is it stored in the war files themselves? I have looked at both the alfresco.war and share.war and I cannot find it. I've also looked throughout the entire install. Are you sure it is named that specifically?
I took the name from an Alfresco 4.2 install because I currently have no Alfresco 5 install that includes the SharePoint protocol module. It could also be called alfresco-community-spp-5.0.b.jar or just alfresco-spp-5.0.b.jar - I am actually not aware if they have changed the naming between versions.
