Thank for your answer, but it doesn't work, in this path : /var/lib/xwiki/data/, I had just : drwxr-xr-x 6 tomcat7 tomcat7 4096 janv. 23 16:47 ./ drwxr-xr-x 3 root root 4096 janv. 16 15:48 ../ drwxr-xr-x 3 tomcat7 tomcat7 4096 janv. 16 16:14 extension/ drwxr-xr-x 3 tomcat7 tomcat7 4096 janv. 16 16:19 jobs/ drwxr-xr-x 2 tomcat7 tomcat7 4096 mars 14 07:00 lucene/ -rwxr-xr-x 1 root root 795 août 12 2013 solr* drwxr-xr-x 3 tomcat7 tomcat7 4096 févr. 17 11:25 storage/ I tried to change rule for solr like that : -rwxr-xr-x 1 tomcat7 tomcat7 795 août 12 2013 solr* But, the result is the same. Is it normal to have just a solr file and not a directory ? -- View this message in context: http://xwiki.475771.n2.nabble.com/Component-manager-has-not-been-initialized...
