this one looks unfamiliar to me. my gem list of working rails-2.3.8
application with jruby-1.5.1 is (I guess the rack-1.1.0 can be omitted
and
jruby-openssl is optional)
$ gem list
*** LOCAL GEMS ***
actionmailer (2.3.8)
actionpack (2.3.8)
activerecord (2.3.8)
activerecord-jdbc-adapter (0.9.4)
activeresource (2.3.8)
activesupport (2.3.8)
jdbc-mysql (5.0.4)
jruby-openssl (0.7)
rack (1.1.0)
rails (2.3.8)
rake (0.8.7)
maybe that helps.
regards Kristian

What DB are you using?

i didnt update i used it from the begining but i think there is some
thing missing i dont know. maybe the configuration file of the database.
my database.yml looks like this:
development:
adapter: jdbc
database: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost/shoplet_dev
username: shoplet_dev
password: XXXXXXXXXXXXX
pool:
timeout: 5000
i’v tryed to change the adapter from jdbc to mysql but it says it cant
find the file to load
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:migrate
!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please
install
the mysql gem and try again: gem install mysql.
rake aborted!
no such file to load – mysql

so again me:

database: test_development

and again may be it helps. Kristian

And I’m telling you that you should update your adapter.
maybe the configuration file of the database.
my database.yml looks like this:
development:
adapter: jdbc
database: com.mysql.jdbc.Driver
“database” is the DB/schema name, so change it to (presumably, based
on the URL you show)
database: shoplet_dev
and add this:
driver: com.mysql.jdbc.Driver

changing the adapter to mysql results this error

first it asks me to install the mysql gem. as you can see i did but it
still gives me the same error. should i restart some thing ?

And presumably you do have the Connector/J jar file somewhere
in your classpath?
