I'm still using Tomcat 7 (7.0.52 on Ubuntu 14.04) and I never had this
kind of issue.

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

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.

Hello Thomas,
THanks for your help.
That's the strange behaviour.
Catalina log file came with lot of messages from solr (some indexing
problems), but I do have on the browser only a blank page.
I just changed the Xmx java tuning from 512 to 1024 (I though it was
may be a memory error).
But same behaviour : on launching a percentage on the browser from 12
to 50% and a blank page.
Last Catalina :

It's the first time I see this error.
Not even sure what a persistent session is. Maybe Tomcat is configured
to stored the session on disk to get it back when restarting and
something put a not serializable object
(DefaultStringEntityReferenceResolver
which is indeed not serializable) in it.
Is XWiki running properly after that ? Even if it's indicated GRAVE it
seems to me you just lost this part of the session but XWiki does not
really expect the session to be serailized anyway so you should
probably disable that if possible.
