I have a rails application deployed to jboss as a war packaged using warbler. The application has been working great for a while now.
I am looking to change the rails application so that rails, all gems and their dependencies are vendor'd. To that extent I have it working great and can boot the application locally using mongrel with no issues, and can also build the war with no issues
However when I deploy the war to jboss it fails to load the application successfully saying it cant find activerecord-jdbcmysql-adapter.
2010-10-26 14:20:23,281 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/lmd4]] (main) unable to create shared application instance
org.jruby.rack.RackInitializationException: Please install the jdbcmysql adapter: `gem install activerecord-jdbcmysql-adapter` (no such file to load -- active_record/connection_adapters/jdbcmysql_adapter)
This is what i have done so far:
Make sure config/warble.rb has an entry for activerecord-jdbcmysql-adapter
config.gems += ["activerecord-jdbcmysql-adapter", "jruby-openssl"]
Manually unpacked the war and confirmed the gems are present

I dunno what could be causing this but if anyone has any ideas please share?
JBoss 5
Rails 2.3.10
JRuby 1.5
Thanks
Could be a JBoss/JRuby-Rack interaction issue. We've had some reports in the past of this not working due to JBoss' use of VFS in class and resource paths and URLs. You could be tripping on this as well.
Can you try the same war file in Tomcat 6 to isolate JBoss as part of the equation? Then please post a bug at http://kenai.com/jira/browse/JRUBY_RACK or http://bugs.jruby.org/.

I am writing Unit Tests in Objective C.
The following is my code:
NSString *testTempDirectory = [NSString stringWithFormat:#"%#%#", NSTemporaryDirectory(), #"DC_Tests"];
NSURL *parentDirURL = [NSURL fileURLWithPath:testTempDirectory];
NSURL *testFolderURL = [NSURL fileURLWithPath:testFolderPath];
Now the path in testFolderURL is returned as
/var/folders/31/2dpztnmx4fzfxb87qtn5_n0wc49pvz/T/DC_Tests/testFolder/
But the original path is
/private/var/folders/31/2dpztnmx4fzfxb87qtn5_n0wc49pvz/T/DC_Tests/testFolder/
The original path is my expected path and since it is different, my assertion is failing.
Any idea as to how do I get the complete path.
Note: I tried absolute string, doesn't help.
Note that in Mac OS, the var folder is actually a linked folder to /private/var

So the simplest way to fix your test is to ignore the /private part from the path. (We had a similar issue with paths that contain the tmp folder on Mac OS as well)
I keep receiving the error SQLite3::ReadOnlyException: attempt to write a readonly database: UPDATE "users" SET "current_sign_in_at" = ?, "sign_in_count" = ?, "updated_at" = ? WHERE "users"."id" = ? when trying to sign into my Rails 4 app which uses the devise gem.
I figured it has something to do with permissions on the dev db so checked out the permissions of the dir first, it has a + tacked onto the end which after some googling still couldn't figure out what it's doing.

After cd ing into the db dir you can see there's nothing wrong with the permissions on the db itself:
-rw-r--r-- 1 a36971 staff 44K 26 Jan 09:30 development.sqlite3
drwxr-xr-x 5 a36971 staff 170B 22 Jan 20:14 migrate/

-rw-r--r-- 1 a36971 staff 44K 26 Jan 09:23 test.sqlite3
So my questions are:
a) why is it unable to write to the db when there doesn't appear to be anything wrong with the permissions themselves
b) what does the + mean on mac os?
a) why is it unable to write to the db when there doesn't appear to be anything wrong with the permissions themselves
My best guess is that the db/ directory is owned by the root user, whereas the db/*.sqlite3 files are owned by user a36971. It may be necessary for the db/ directory to also be owned by user a36971.
Try changing the owner from root to a36971 for the db directory:
sudo chown a36971 db
b) what does the + mean on mac os?
+ sign means there are additional permission details not displayed by the default output from ls -l. Try running ls -le to see the details (source: http://tech.enekochan.com/en/2014/05/29/plus-and-at-symbols-listing-file-permissions-in-mac-os-x/).
Got the same error after running rails db:reset
Restarting the local server fixed my problem
Im trying to follow a tutorial to do a CORBA assignment.

I do the first step, trying to compile the IDL (from the project root), and it fails.

I found this which says CORBA has problems parsing paths with / in front. But mine doesn't have a /
apparently the Lecturer's instructions were wrong or outdated or the compiler is not fully working but compilation of all files is achieved by
idlj -fall hello.idl
I have a rails app called MBAToolbox. When I enter the directory and type "play", I get the following:
This is not a play application!
That's good! Now I type rails c and I am entered into the rails command line. Clearly this is a rails app. But when I type 'heroku create' and push 'git push heroku master', heroku tries to deploy this as a 'play' app?
I saw on their site that Heroku states:
Heroku Play framework support will be applied to applications that
match:
*/conf/application.conf in any directory except for the modules directory
, when determining to use Play.
I don't have that. My directory is as follows:

Thoughts?
This article on the Heroku dev site covers both ends of this. It has a pointer to the actual source of the Play buildpack, so you can read the code that figures out which buildpack to use. You can also explicitly pick the Rails buildpack instead.
In Ruby or in Rails:-
I need to show output from below code formated as it shows in command prompt.
require 'net/ssh'
Net::SSH.start( hostname, username, :password => password ) do|ssh|
result = ssh.exec!('ls -ltr')
puts result
end
Let me know how is it possible?
Command (ls -ltr) is dynamic and

Try using the <pre> tag. Also make sure that the font you use is one of the monospace fonts like CourierNew.
