[xwiki-users] XWiki 3.5, error when exporting PDF with image

I try to generate PDF from XWiki 3.5. The installation was made from scratch to XWiki 3.4, and imported the documents via XARs from XWiki 3.0.3. Then just upgraded to 3.5, with no problems. *Detailed information: * When I dig the tomcat logs, the error seems to be *c.x.x.p.i.PdfURLFactory - Failed to save image for PDF export java.io.IOException: Failed to create temporary PDF export file with prefix [pdf], suffix [.] in directory [/opt/tomcat/xwiki35/apache-tomcat-7.0.22-with-log4jpgp/work/Catalina/10.10.1.135/xwiki/Ee7wkX8p] at com.xpn.xwiki.pdf.impl.PdfURLFa * However, there seems to be sufficient permissions: *ls -lah /opt/tomcat/xwiki35/apache-tomcat-7.0.22-with-log4jpgp/work/Catalina/10.10.1.135/xwiki/ * *drwxr-xr-x 6 tomcatxwiki35 tomcatxwiki35 4.0K Feb 22 10:47 . drwxr-xr-x 8 tomcatxwiki35 tomcatxwiki35 4.0K Feb 22 10:10 .. drwxr-xr-x 49 tomcatxwiki35 tomcatxwiki35 4.0K Feb 22 10:42 aether-repository drwxr-xr-x 2 tomcatxwiki35 tomcatxwiki35 4.0K Feb 22 10:12 charts drwxr-xr-x 2 tomcatxwiki35 tomcatxwiki35 4.0K Feb 22 10:12 svg drwxr-xr-x 3 tomcatxwiki35 tomcatxwiki35 4.0K Feb 22 10:12 xwiki.plugin.image* And there is also sufficient permissions in these directories as well.. *xwiki.cfg:xwiki.plugins.lucene.indexdir=/opt/tomcat/xwiki35/xwiki/lucene-indexdir xwiki.cfg:xwiki.work.dir=/opt/tomcat/xwiki35/xwiki/work-dir xwiki.properties:environment.permanentDirectory=/opt/tomcat/xwiki35/xwiki/persistent-data xwiki.cfg:xwiki.temp.dir=/tmp/xwiki xwiki.cfg:xwiki.tmp.dir=/tmp/xwiki * Because there are sufficient permissions I wonder why the directory /opt/tomcat/xwiki35/xwiki/work-dir/ is empty? Also, I note that the tomcat wepapps -directory has a file called .fop Is there any advises of where to find more information or how this could be fixed? With Regards, ari
