CentOS 5.3 Tomcat 5.5.23 PostgreSQL 8.1.11 Xwiki 1.8.1 I installed Xwiki 1.8.1 from the WAR file but get a 404 error when I browse to http://host:8080/xwiki. Rather than detailing the procedure here, I posted it to http://rafb.net/p/FhUlVP37.html for (hopefully) easier reading. I did confirm that Tomcat is listening on port 8080 and I get its default page when I browse to http://host:8080/. For the time being, I've disabled SELinux and iptables for testing. I followed the instructions for the installation of Tomcat and PostgreSQL that is detailed on the xwiki.org web site. http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationTomcat http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationPostgreSQL
