Trying to answer to Vincent about Toucan use I am facing a problem while updating a 1.3M1 to 1.3M2 in my test box. Here the error: javax.servlet.ServletException: com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3201 in 3: Exception while saving document XWiki.XWikiPreferences Wrapped Exception: Error number 3211 in 3: Exception while updating archive XWiki.XWikiPreferences Wrapped Exception: Error number 3212 in 3: Exception while loading archive 104,408,758 Wrapped Exception: Error number 0 in 3: Exception while hibernate execute Wrapped Exception: Null value was assigned to a property of primitive type setter of com.xpn.xwiki.doc.rcs.XWikiRCSNodeInfo.diff org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:535) org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:433) org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:236) org.apache.struts.action.ActionServlet.process(ActionServlet.java:1196) org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414) javax.servlet.http.HttpServlet.service(HttpServlet.java:690) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) com.xpn.xwiki.web.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:117) I am using the same MySQL connector than with 1.3M1, mysql-connector-java-5.1.5-bin, and hibernate has been edited to uncomment and set up a MySQL connection. I noticed that hibernate includes a new line (or at least it is I think the first time I read it) in the MySQL configuration comment: We need to set the sql_mode to a less strict value, see XWIKI-1945 And connection.url is slightly different: jdbc:mysql://localhost/xwiki?useServerPrepStmts=false&sessionVariables=sql_mode='' Perhaps I am doing something wrong, but I think I am following the same proces I've used before.
