Hello, I have been running xwiki 3.1 for a while now on Fedora 13 with PostgreSQL/Tomcat. I decided to upgrade to 3.2 by undeploying the previous version of xwiki and installing the 3.2 war and default xar files, reconfiguring hibernate.cfg.xml to access the PostgreSQL database etc. After the new war install and the hibernate.cfg.xml reconfiguration, when trying to connect xwiki, I get: HTTP Status 500 - _____ type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception 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:XWiki.XWikiPreferences Wrapped Exception: Error number 3211 in 3: Exception while updating archive XWiki.XWikiPreferences Wrapped Exception: Error number 0 in 3: Exception while hibernate execute Wrapped Exception: could not load an entity: [com.xpn.xwiki.doc.rcs.XWikiRCSNodeContent#component[docId,version1,version2 ]{docId=104408758, version2=1, version1=24}] org.apache.struts.action.RequestProcessor.processException(RequestProcessor. java:535) org.apache.struts.action.RequestProcessor.processActionPerform(RequestProces sor.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:617) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) com.xpn.xwiki.web.ActionFilter.doFilter(ActionFilter.java:128) org.xwiki.wysiwyg.server.filter.ConversionFilter.doFilter(ConversionFilter.j ava:144) com.xpn.xwiki.plugin.webdav.XWikiDavFilter.doFilter(XWikiDavFilter.java:68) org.xwiki.container.servlet.filters.internal.SavedRequestRestorerFilter.doFi lter(SavedRequestRestorerFilter.java:217) org.xwiki.container.servlet.filters.internal.SetCharacterEncodingFilter.doFi lter(SetCharacterEncodingFilter.java:109) and in catalina.out, I get a lot of those </property> <property> <showannotations></showannotations> </property> <property> <showattachments></showattachments> </property> <property> <showcomments></showcomments> </property> <property> <showhistory></showhistory> </property> <property> <showinformation></showinformation> </property> <property> <skin>XWiki.DefaultSkin</skin> </property> <property> <smtp_port></smtp_port> </property> <property> <smtp_server>127.0.0.1</smtp_server> </property> <property> <smtp_server_password></smtp_server_password> </property> <property> <smtp_server_username></smtp_server_username> </property> <property> <stylesheet>style.css</stylesheet> </property> <property> <stylesheets>style.css</stylesheets> </property> <property> <tags></tags> </property> <property> <title>$tdoc.getRenderedTitle("plain/1.0") ($doc.fullName) - XWiki</title> </property> <property> <upload_maxsize>671088640</upload_maxsize> </property> <property> <validation_email_content>#set ($wikiname = $request.serverName) #set ($host = ${request.getRequestURL()}) #set ($host = ${host.substring(0, ${host.indexOf('/', ${mathtool.add(${host.indexOf('//')}, 2)})})}) Subject: Validate your account on ${wikiname} Hello ${xwiki.getUserName("XWiki.$xwikiname", false)}, This email address was used to register a new account on ${wikiname}.
