Hi All I am trying to set up XE to use an Oracle 10 XE database using a Tomcat but I seem to be missing some important point I downloaded the war file to set it up followed the instructions in the setup pages, have had issues with getting it to parse files and have now got to here where I seem to be connecting to my database but not getting it to function I am an Oracle DBA and do work with Oracle Middleware, so am familiar with much of the concepts, not so much with Hibernate and Tomcat This is the error I am seeing javax.servlet.ServletException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3001 in 3: Cannot load class com.xpn.xwiki.store.migration.hibernate.XWikiHibernateMigrationManager from param xwiki.store.migration.manager.class Wrapped Exception: Error number 0 in 3: Exception while hibernate execute Wrapped Exception: could not execute query 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.wysiwyg.server.filter.ConversionFilter.doFilter(ConversionFilter.java:152) com.xpn.xwiki.web.ActionFilter.doFilter(ActionFilter.java:117) com.xpn.xwiki.plugin.webdav.XWikiDavFilter.doFilter(XWikiDavFilter.java:68) com.xpn.xwiki.web.SavedRequestRestorerFilter.doFilter(SavedRequestRestorerFilter.java:295) com.xpn.xwiki.web.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter Server details are Centos 5.4 32bit Apache Tomcat/5.5.23 Oracle 10 database Xe xwiki-core-2.1.1.jar OpenJDK Runtime Environment (build 1.6.0-b09) I have a IBM Java 1.6 jre installed that I could use, should I use that instead or will this work with OpenJDK Any help appreciated Hibernate.cfg.xml <?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- Please refer to the installation guide on http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation for configuring your database.
