If I deploy an EAR on a WAS and the EAR is missing an EJB described in ejb-jar.xml, it complains at deployment time. But if I have defined a resource-ref for a jndi datasource in ejb-jar.xml, it does not complain unless i execute a test case that actually tries to lookup the datasource.
Is there a configuration that can be tweaked so that when deploying an EAR, it will complain if any of the resource-references have not been created on the server? So that I know immediately that some resource-references are missing

I have a Rails app that I package as a war file for deploying to Tomcat using Warbler. And it works, but the problem is I don't know how to configure the runtime properties like secret_key_base. I use the standard setup of using secrets.yml, with production variables coming from environment variables. But I don't know how to set the variables while still keeping them out of source control.
Ideally I'd still like to be able to deploy the war file automatically, by just dropping it into the webapps/ directory, but I suppose I could edit the server config file? Or is there a better way of handling this?
either do it the same way as you would in a Rails server ... let it read from ENV (of course you will need to make sure Tomcat has the environment variable set).
alternatively you can set it in a web.xml if you're packaging and than do a $servlet_context.getAttribute('foo') in secrets.yml ... or read it from a file location that only the server's tomcat username can access etc.
sky is the limit here - you basically need to decide what fits your deployments the best.
I am currently using a platform where multiple web applications must interact with each other in a frameset. This set of web applications and the frameset is hosted on Tomcat.
Now the application we're working on is developed with jRuby and Rails. Is there anyway I can run my development environment inside of Tomcat similar to just running the jRuby -S Rails Server command so I can effectively debug?
The only way I've found is to generate a war using warble and then modifying the exploded war which seems really hacky. Any thoughts?
EDIT: I think my best bet is to generate a war, gut it, use symbolic links and figure out what gems / libs I need to copy from the war generation process. It's the best way I can think of.
one option to explore: deploy a little servlet to Tomcat which returns
HTTP/1.1 301 Moved Permanently
Location: http://localhost:3000
So far the best solution I have found is to setup a reverse proxy with Tomcat and point it to the Rails development server. This allows it to run, as expected on the client side, while still giving me debug control.
When I get a chance to do some more testing I'll edit my answer to include additional information.
go to the webapps folder in tomcat where you have deployed the war file, then find the web.xml file inside the expanded war file
The path to this file is generally /var/lib/tomcat7/webapps/your-project-here/WEB-INF/web.xml and inside this file you should find the
Changing this is one way to go about.

I'm trying to follow the tutorial here.
I have declared the dependency for the database migration plugin in my BuildConfig.groovy file with runtime ":database-migration:1.0" and then compiled. I have also comment out the dbCreate line of my production settings in my DataSource.groovy file. My production database is empty with no tables in it.
I then try to run the two commands to generate my initial change log:
grails dbm-create-changelog
grails prod dbm-generate-gorm-changelog --add changelog-1.0.groovy
The problem is the first command creates tables in my development database, not my production database. Then the second command fails to create the changelog-1.0.groovy file it is supposed to create (I assume) because the production database never had any tables created. I get several errors that say Hibernate failed to index the database and I a bunch of errors like this:
| Error 2012-07-10 08:40:28,704 [Compass Gps Index [pool-11-thread-2]] ERROR util.JDBCExceptionReporter - Table 'mygrailsapp_prod.some_class' doesn't exist
Even when I comment out my development settings in my DataSource.groovy file Grails is still looking for my development database. I should point out though if I drop the prod off the second command a the changelog-1.0.groovy file generates fine, though I am unclear if will somehow be messed up because it was generated off the development database (which had no tables in it until I ran the first command) instead of the production database.
What am I doing wrong here?
The problem is the first command creates tables in my development database, not my production database.
That's probably because it is running against the development environment and you still have its dbCreate set to "update"
Then the second command fails to create the changelog-1.0.groovy file it is supposed to create (I assume) because the production database never had any tables created.
That's not entirely accurate. From the link you posted it says after that step: "Note that your database will remain empty!" The database tables will only get created when you execute a dbm-update command. That's when the changelog actually executes.
I think the blog you linked to isn't entirely accurate on the prod switch for the second command. Nothing about your Domains is environment specific. So just leave that off and you should be able to keep going. I'm not sure why that error is being thrown. It really doesn't make sense.
Bootstrap executes fine during run-app (database is seeded). But it doesn't appear to get invoked when Tomcat deploys the war (nothing in the database).
Does the Bootstrap get run during war deployment? If not, is there a way to make it run?
Specifically I am wanting my sample data to seed the database.
Yes it does....
i would look to make sure you have your environments configured properly if you see thing working in development, but not production
I'm working on a Rails site that connects to an Oracle database, and though I didn't build the site from scratch, I'm doing maintenance work. The site uses the delayed_jobs plugin to handle some background tasks and I'd like to be able to run rake jobs:work on the development server to periodically process all jobs in the queue (due to the server's configuration, running a daemonized version of the script on the development server isn't an option). However, whenever I try running the command, I get the following classic Oracle error:
error while trying to retrieve text for error ora-12154
Ordinarily, I'd think this would be an authentication problem (e.g. incorrect credentials in database.yml), but the site is up and running fine (and doing lots of database stuff). I've tried adding RAILS_ENV=production as a parameter to rake to force it to run in in the production environment, but got the same error (there are two separate rails installations for the production and development versions of the site, and I've set the "development" and "production" credentials in development's db config file to be identical).
I'm not sure what could be causing this error, and I don't have a ton of experience using Oracle with rails. Any suggestions?
Thanks a lot!

EDIT (10/26/09): Still can't figure out what's causing the problem here. The app continues to run (and talk to the database) without a problem, but rake keeps throwing DB errors. So does script/console, which shows a prompt but first complains with the same Oracle error message. I'm going to keep looking, but I'm running out of ideas...
EDIT(10/26/09, later): Following the advice of this link, I set both ORACLE_HOME and TNS_ADMIN to point to the directory where tnsnames.ora lives. Just setting ORACLE_HOME had no obvious effect, but now that TNS_ADMIN points to the right place, I've started getting segmentation faults whenever I try to open the console or run rake:
/usr/local/lib/ruby/site_ruby/1.8/oci8.rb:184: [BUG] Segmentation Fault
and get booted unceremoniously back to the prompt. Any further ideas?
Finally got it...turns out that ORACLE_HOME wasn't being correctly set as an environment variable for my user account. Now rake, script/console, etc. are humming along happily.
The oracle error says the following:
ORA-12154 is generated by the oracle network layer. TNS error message is thrown during the logon process to a database. This error indicates that the communication software in Oracle ( SQL *Net or Net8 ) did not recognize the host/service name specified in the connection parameters. This error almost always indicates a misconfiguration of the oracle tns entries.
Can you connect to your oracle instance using sqlplus or another db tool?
It is odd that the app runs fine though.
Is there an $ORACLE_SID laying around somewhere that could be pointing to a db that doesn't exist?
IN sql server I would probaly run profuiler to see what is actually being sent vice what I think I have set up. I'm sure Oracle aslo has some type of profiling utility. I would try that and see, you may find it isn't using the credentials you tink it is.
Well, as Mike mentioned, ora-12145 means TNS couldn't resolve the database identifier (TNS is Oracle's name-to-database mapping, sorta-kinda like DNS). If you can find your tnsnames.ora file, you can see what databases are configured there and compare that to the database.yml file. The fact that it works as a delayed job but not from the command line is a bit odd, though, and makes me think that perhaps there are some environment variables being set in one context that aren't in the other.
If neither of those pan out, there's a long list of troubleshooting suggestions at http://ora-12154.ora-code.com that are specific to that error code.
