parameter except this one about short URL:

my logs/localhost.2014-10-29.log doesn't indicate the problem but I found that your
xwiki-6.2.2/WEB-INF/web.xml file contain:
  <error-page>
    <error-code>404</error-code>
    <location>/bin/view/Main/DocumentDoesNotExist</location>
  </error-page>

  Hello,
 On my Tomcat server / Xwiki 6.2.2, I have this log (catalina.log) when I start my Tomcat

 I checked on my Xwiki and effectively Main.DocumentDoesNotExist ... does not exist. :-)
 Do you think this log is normal? 
No it’s not normal. Check your tomcat locahost* log file for more details.
  Do you have the same?  
Haven’t seen that but didn’t test on tomcat.
  I must create a custom Main.DocumentDoesNotExis?
No
Thanks

  Thxs for any help.
