Hello Thomas,
Well, this is strange story.
For persistent session I found a tip here : uncomment the rule in
context.xml :
<Context>
<!-- Default set of monitored resources -->
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<!-- Uncomment this to disable session persistence across Tomcat
restarts -->
<Manager pathname="" />
<!--
<Manager pathname="" />
-->
**end of context.xml**
And it is OK
The answer to your question :
root@CESAP-WIKI01:/usr/lib/xwiki/WEB-INF/lib# ll xwiki-platform-container-*
-rw-r--r-- 1 root root 24971 juil. 29 17:26
xwiki-platform-container-api-8.2.1.jar
-rw-r--r-- 1 root root 35318 juil. 29 17:26
xwiki-platform-container-servlet-8.2.1.jar
The jar file is there.
Could it be a problem with tomcat 7.0.56 ?
Will it be easier for me to migrate to tomcat8 ? and put away the tomcat7
unstable
Thanks
Cordialement

Ok this time it's a very different error which indeed looks more serious.
But it still seems related to persistent storage of the session and in this
case it seems to be trying to load a saved request (which is really not the
kind of thing that make sense to store). For me your Tomcat is in a pretty
weird state and try to load stuff that don't make much sense in the context
of XWiki but I don't know anything about persistent storage. Seems to be to
have something to clean somewhere and some option to disable (if it's still
enabled).
Tomcat cannot find the class
org.xwiki.container.servlet.filters.SavedRequestManager$SavedRequest
which is supposed to be located in jar
/usr/lib/xwiki/WEB-INF/lib/xwiki-platform-container-servlet-<version>.jar.
You should probably check if you have this jar file and if tomcat is allowed
to read it.
