no login window appears after update

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Follow the upgrade instructions (export existing projects, move /srv/webanno 
to safe location, re-create /srv/webanno with old settings files (I created a 
copy of the original webanno database, named it webanno2, and changed the name 
of the database in settings files), re-start webanno with new 2.0.12.war file, 
re-create users from mysql dump, re-start WebAnno service);
2. Try to connect to WebAnno Server;
3. No login window is shown -- neither in Mozilla nor in Chrome - the displayed 
page is completely blank, there is no HTML source code;

What is the expected output? What do you see instead?
Login window

What version of the product are you using? On what operating system?
WebAnno: webanno-2.0.12.war
Apache Tomcat/6.0.35
JVM: 1.6.0_32-b32
OS: Linux hebe 3.2.0-57-generic #87-Ubuntu SMP Tue Nov 12 21:35:10 UTC 2013 
x86_64 x86_64 x86_64 GNU/Linux

Do you need database description or any additional logs?

Original comment by wlsidore...@gmail.com on 17 Nov 2014 at 5:51

You copied the original database. That will not work. You need to start with a 
completely empty database and let WebAnno 2.0.12 recreate the schema from 
scratch.

Now, I've DROP'ped the database webanno2, created an empty one, and re-launched 
the WebAnno service twice, but there is still no login window. Here are the 
contents of `webanno2`:
mysql> use webanno2

You can turn off this feature to get a quicker startup with -A

16 rows in set (0.00 sec)

mysql> SELECT * from users;
Empty set (0.00 sec)

Here is /srv/webanno/settings.properties:
database.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
database.driver=com.mysql.jdbc.Driver
database.url=jdbc:mysql://localhost:3306/webanno2
database.username=webanno
database.password=....

format.properties is probably not needed.

Can you please provide the log you get when starting Tomcat/WebAnno 2.0.12 now?

Are you sure you are entering the correct URL? E.g. if you deploy the WAR under 
the name "webanno.war" into the webapps folder, your URL would be something 
like "http://localhost:8080/webanno". If you use another name, e.g. 
"webanno-2.0.12.war" the URL changes accordingly 
("http://localhost:8080/webanno-2.0.12").

If you are running your Tomcat behind an Apache and you changed the name of the 
WAR, then make sure also to update your proxy configuration in Apache.

Sorry, I did not know about the URI change. I tried it yesterday, and the web 
page simply hung, but I could not reproduce this behavior today. Now, the 
website seems to work. You can probably close the issue.

Good to hear it works for you now.
