8.1 requires Java 8 so you need to make sure you configure Tomcat to use it. Note: it's possible the JVM is explicitely set in /etc/default/tomact7 (in which case Tomcat won't use the default JVM).

"Invalid byte tag in constant pool: 15" still looks like a Java version issue. Could you check what version of Java started with "ps aux | grep tomcat" ? On Wed, May 25, 2016 at 12:41 PM, Stéphane LASSIRE <slassire(a)cesap.asso.fr> wrote: -- Thomas Mortagne

I see you are using tomcat 7.0.28 - probably your are still on wheezy? There are some bug reports for that message; it seems upgrading tomcat helps, e.g.: http://stackoverflow.com/q/23541532 http://stackoverflow.com/q/23484098 However the tomcat with wheezy is just too old: https://packages.debian.org/wheezy/tomcat7 The tomcat with jessie should work https://packages.debian.org/stable/tomcat7 Maybe try "wheezy-backports" if you do not want to update to jessie (I have never done that myself, so I cannot be of much help here) Alternatively it might help editing xwiki's web.xml manually by adding a metadata-complete="true" as suggested here: http://stackoverflow.com/a/12730059 though I have not tried this and do not really understand why it should help HTH Clemens ----- Ursprüngliche Nachricht ----- Von: Stéphane Lassire Am: Wednesday, 25.05.2016, 12:48 An: Xwiki Users Betreff: Re: [xwiki-users] Error upgrading Debian mit freundlichen Grüßen Clemens Klein-Robbenhaar -- Clemens Klein-Robbenhaar Software Development EsPresto AG Breite Str. 30-31 10178 Berlin/Germany Tel: +49.(0)30.90 226.763 Fax: +49.(0)30.90 226.760 robbenhaar(a)espresto.com www.espresto.de HRB 77554 B - Berlin-Charlottenburg Vorstand: Maya Biersack, Peter Biersack Vorsitzender des Aufsichtsrats: Dipl.-Wirtsch.-Ing.

Hi Sorry, just seen these emails. One thing I forgot to mention last night (sorry I was quite tired) was that I uninstalled all the previous versions of the JDK I see from your email below that you still have java-6-openjdk and java-7-openjdk Once you uninstall the old version, and make sure you have the JDK_DIRS variable with the correct path (as you have), it will work. I had to uninstall the openjdk-7-headless (or similar). I hope that helps.
