You might want to check the log files in the tomcat installation directory for startup
errors.
(Unfortunately tomcat writes logs in several files, at least last time I checked. Just
look into everything that has updated recently in the logs dir)
A possible cause for the problem is that you have two xwiki webapps running in the same
tomcat;
maybe caused by having a custom context.xml duplicated or the like (?)
But without the startup error from the log this is just a wild guess

Betreff: [xwiki-users] XWiki startup HTTP 500 issue
Good day.
Had xwiki set up and running for a while now. This morning windows 7 dicided
to do a system recovery on startup. Now when I try to run XWiki I get a HTTP
500 error:
java.lang.NullPointerException
com.xpn.xwiki.web.Utils.getContextComponentManager(Utils.java:695)

org.xwiki.resource.servlet.RoutingFilter.doFilter(RoutingFilter.java:137)
Any ideas where to start looking for the problem? I went over the
configuration and all looks fine and MySQL is running and tomcat7 is
running..
Not sure how to recover.
Thanks
