Hello, we are currently running XWiki Version 0.9.840 in our intranet. Due to regular problems we have with pages history being corrupted, absence of wysiwig editor, we would like to upgrade our xwiki version. It seems that the replacement for that xwiki is "xwiki enterprise 1.2.2". We tried to do that upgrade on a copy database, but we hit that problem upon accessing: java.lang.UnsupportedClassVersionError: org/exoplatform/container/PortalContainer (Unsupported major.minor version 49.0) It seems (http://www.nabble.com/Plexus-version-error-td14888606.html) that it's linked to the presence of exo components that requires java 1.5. However, since that tomcat run also other applications, upgrade to 1.5 is not an option. What is the latest xwiki that works with 1.4 version and where should i go to download it? Also, has the authentification mecanism been changed since 0.9? We are using a custom password checking class (xwiki.authentication.authclass=be.rmi.intranet.XWikiNISAuthService). Is that still supported? If no, is container managed authentification supported? Thanks -- David Delbecq Institut Royal Météorologique Ext:557
