I am trying to create a simple Rails 2.2.2 app using jruby 1.1.5. The
application is using mysql DB. The gems installed are:
$jruby -S gem list
*** LOCAL GEMS ***
actionmailer (2.2.2)
actionpack (2.2.2)
activerecord (2.2.2)
activeresource (2.2.2)
activesupport (2.2.2)
glassfish (0.9.0)
jdbc-mysql (5.0.4)
rack (0.4.0)
rails (2.2.2)
rake (0.8.3)
rspec (1.1.11)
sources (0.0.1)
[/c/dev/rails/book]
During migration I get this error from Rails that 2.2.2 no longer ships
mysql.rb:
----------
$jruby -S rake db:create
(in C:/dev/rails/book)
!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please
install t
he mysql gem and try again: gem install mysql.
rake aborted!
no such file to load -- mysql
----------
When I try to do: jruby -S gem install mysql, it can't install as jruby
does
not support native extension. So the only option I have is to
install activerecord-jdbcmysql-adapter or someone got any better way to
go
past these errors?
-------------
$jruby -S gem install mysql
JRuby limited openssl loaded. gem install jruby-openssl for full
support.

Hi Vivek -
As I understand it (and I'm no expert), what you've done is the
correct way to fix that. I also have a Rails 2.2.2 app that I run with
JRuby 1.1.5, and I have these gems installed to support it:
activerecord-jdbcmysql-adapter (0.8.2)
jdbc-mysql (5.0.4)
In my database.yml file, the adapter is configured like this:
development:
host: localhost
adapter: jdbcmysql
database: tt_dev
port: 3306
username: root
password:
Hope that's helpful (or at least not wrong). :)

Hi Vivek Seems like you're missing the jdbc adapter gem install activerecord-jdbcmysql-adapter and change the adapters entry in database.yml to: adapter: jdbcmysql /Mikael Vivek Pandey wrote: > activerecord (2.2.2) > > rake aborted! > JRuby limited openssl loaded. gem install jruby-openssl for full support. > ---------------- > > -vivek. > --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email

I think another option is to copy the Ruby MySql driver to <rails app>/lib. You can download it from http://www.tmtm.org/en/ruby/mysql/, or just copy it from an older version of activerecord (e.g. gems/activerecord-2.1.2/lib/active_record/vendor/mysql.rb). Probably better to use the jdbc adapter anyway, just wanted to point out this option too.

Which raises another question; other than age/support, what IS the reason for not using the old mysql adapter? Is the JDBC one better in any way? -- Twitter: http://twitter.com/campbellmichael --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email

Yeah. The MySql adapter has native code that does not run in the JVM. And the pure Ruby variant does not work on 4.1 or 5.x. On Mon, Dec 1, 2008 at 7:24 AM, Michael Campbell <

Wel, the mysql adapter works fine on JVM on windows platform. Although for some reason it does not work on ubuntu. -vivek.

If you got an error on Ubuntu like this:
/home/ryan/opt/jruby-1.1.5/lib/ruby/1.8/mkmf.rb:7: JRuby does not
support
native extensions. Check wiki.jruby.org for alternatives.
(NotImplementedError)
from /home/ryan/opt/jruby-1.1.5/lib/ruby/1.8/mkmf.rb:1:in `require'
from extconf.rb:1
ERROR: Error installing mysql:
ERROR: Failed to build gem native extension.
It's because JRuby doesn't run the native extensions. Your only real
choice
in that case it to install the jdbc variant.
