JBoss 4.0.2 Postgresql 8.0.3 Debian Sarge AMD64

Hi, I have followed the installation instructions but for some reason I do not understand I get the following exception: 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 3221 in 3: Exception while saving class XWiki.XWikiPreferences Wrapped Exception: Error number 3222 in 3: Exception while saving class XWiki.XWikiPreferences Wrapped Exception: Could not execute JDBC batch update com.xpn.xwiki.XWiki.getMainXWiki(XWiki.java:142) com.xpn.xwiki.XWiki.getXWiki(XWiki.java:202) com.xpn.xwiki.web.ViewEditAction.execute(ViewEditAction.java:117) org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:421) org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:226) org.apache.struts.action.ActionServlet.process(ActionServlet.java:1164) org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:397) javax.servlet.http.HttpServlet.service(HttpServlet.java:697) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) com.xpn.xwiki.web.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:127) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81) Is there a fool (==me) proof way of installing xwiki with JBoss, PostgreSQL and Debian Sarge AMD64? Is there anyone actually using XWiki with JBoss?? TIA -- Groeten, Joost Kraaijeveld Askesis B.V.
