Hello, I have a problem with office presentation viewer. It is not displayed presentation slides when I use it because the jpg url is incorrect. I use a tomcat server and proxy-ajp on apache2 (i followed xwiki doc) My xwiki is on root of my server name. If I click on the eye icone from an odp file in a page, my browser goint to this url: (under /bin/view/): http://my.server.name.fr/bin/view/Encyclop%C3%A9die/Agenda%20du%20managemen… but didn't display slide . I saw with firebug that my browser didn't manage to display jpg file generated by xwiki: (/tmp) http://my.server.name.fr/tmp/officeviewer/document%3Axwiki%3AEncyclop%C3%A9… I use this in my server.xml: <Engine name="Catalina" defaultHost="my.server.name.fr"> <Host name="my.server.name.fr" appBase="webapps" workDir="/home/path/work"> and found target jpg file on /home/path/work/ROOT/xwiki-temp/tmp/officeviewer/xwiki/xxxxxx subdirectory I didn't found source of this error. If someone could help me? Thxs Pascal B
