Undefined method class_eval for ActiveRecord::ConnectionAdapters::JdbcAdapter

Ruby JRuby
1

Hi,

I am trying to port an application from c-Ruby to JRuby. I have an
Oracle database backend and have added the JDBC driver jars to the lib
dir of JRuby. Also, I have set the required connection parameters in
database.yml.

Webrick is starting fine, but for any request, I get the following
error:

RedirectionController: missing default helper path redirection_helper

Hi,

I’ve been trying to get this running but am not successful. I have tried
with the oracle jdbc adapter as well as the old ActiveRecord_JDBC
package. I am running Rails v1.2.6. My current platform uses Ruby 1.8.7.

Looking forward to your help.

Thanks and regards

Hi,

I tried the same with Rails 2.3.4 and the Oracle connection worked fine.
It seems that JRuby adapter doesn’t support Rails 1.2.6 completely.

What’s the oracle jdbc driver you use?
Or anything I missed?
