a) If you are using Internet Explorer, go into the "extra" or "preferences" settings, and
find and disable the "show friendly error pages" option.
You might then see what is really returned by Tomcat (or whatever the error
really is).
b) out of the logfile which you posted earlier, I have extracted the following part, which
shows
1) the end of a previous Tomcat startup sequence :
Jul 21, 2016 8:13:36 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 128687 ms
2) Then almost immediately (4 s later), a shutdown sequence :
Jul 21, 2016 8:13:40 PM org.apache.catalina.core.StandardServer await
INFO: A valid shutdown command was received via the shutdown port.
Stopping the Server instance.

INFO: Server startup in 146344 ms
Tomcat is running again, and it took approximately 2 minutes for this startup.
In that logfile, there are more startup/shutdown sequences than shown above
here.
There are no errors visible in that logfile, from the Tomcat point of view, apart from the
database connection.
But,
it is quite difficult to help you determining why you cannot get to the Tomcat homepage,
because we have no idea *when* you actually trid to access that page, nor from where.
And we also do not know if you were trying to access it while Tomcat was running, or while
Tomcat was shut down (or incompletely started).
So, could you, exactly in this sequence :
- close your browser
- stop Tomcat
- wait 1 minute
- then (important) : delete all the Tomcat logfiles
- then start Tomcat and note the time at which you do that
- then, *wait 3 minutes*
Then open your browser, try to access the Tomcat homepage, and note
- the complete URL which you use to do that
- the exact time at which you do that
- the exact error which you get in the browser
- then shutdown Tomcat and note when you did this
- wait a couple of minutes
- then edit the new Tomcat logfile, and copy/paste the whole logfile *here* (and *not* at
the top of your email) and also give us the other information requested above, below the
logfile content.
