I am using JRuby and I have to deploy on Tomcat. My web app is working
fine in the dev envirmonment, with Mongel, but when I deploy on Tomcat
I get “We’re sorry, but something went wrong on Tomcat”.
The problem is that production.log only shows:
The file permission and directory are 777.
Any idea how I can understand what is the problem.

? literally, it says “went wrong on Tomcat”??? That’s, erm, strange.

Have you tried running in dev mode on Tomcat?
Have you looked at the Tomcat log for the app?

OK, then how are you creating the WAR?
Regardless, once it’s deployed and expanded, find WEB-INF/web.xml,
change production mode to development and restart Tomcat.
You should at least get a usable error message then.

Thanks, for your help.
I created a super simple Rails app with generate scaffolding, one
table with one column. On tomcat on my Win PC the app is working. On
Tomcat on Solaris not. My web.xml is this:
As you can see is in production. I used this tutorial to create the
war:
I used:
warble config
added:
config.gems += [“activerecord-jdbcmysql-adapter”, “jruby-openssl”]
then:
warble
Copied the WAR in Tomcat on my PC and and it worked, on Solaris not.
The database (on MySql) as GRANT ALL . for ‘root’@‘%’ it should not
be a problem.
The log of Tomcat:
-bash-3.00$ tail /opt/tomcat/logs/catalina.2009-10-13.log

The log of production.log is empty but has 777 permission. I have zero
information to figure out what is going on!!!

I changed to development but I cannot see any change, except when I
call http://10.3.111.79:8080/test/posts, Tomcat hangs, does not reply.

Yes, I can see that. As I said, if you change it to development
mode and restart Tomcat, you’ll get more information about the
problem.

I am deploying a test. I think I have mess up ROOT.xml few days ago. I
will try to have a clean Tomcat, then I will deploy test.war again.
Thanks.

Geez, NO. Just FIX the stupid ROOT context file. The error message
is telling you exactly what’s wrong.
No need to reinstall Tomcat, waste of time.

Well I have wasted my time by reinstalling Tomcat 
I cannot see any error in catalina.2009-10-13.log, so the ROOT.xml
error is gone. But I still have “We’re sorry, but something went
wrong.” I changed web.xml to development, but I cannot see any log. I
must be a severe error. I have the MySql connector in tomcat/lib
directory. I might be that the web app is not able to connect to
MySql, which is in another server.

There you go. Fix that first.
Are you deploying your test WAR as ROOT or as ‘test’, as it seemed
from your previous mail?

The problem is that form that server I cannot connect to the MSql
server, so the error is, no DB connection. Ii there a way to test the
DB connection of a Rails application?

Did you restart Tomcat after changing to development mode?

So make sure your database.yml entries for both development and
production are correct, and you can connect to the DB manually from
the command line using that info.

Are you saying you can’t connect manually from the command line?
Then there’s no way Rails is going to be able to
And “can’t connect” because? bad password? username? firewall
issue?
