Key: JRUBY-2329
URL: http://jira.codehaus.org/browse/JRUBY-2329
Project: JRuby
Issue Type: Bug
Components: ActiveRecord-JDBC
Affects Versions: JRuby 1.1RC1
Environment: ruby 1.8.6 (2008-01-07 rev 5512) [sparc-jruby1.1RC1],

Reporter: Ralf Sigmund
When attempting to connect to a DB2 database, I get the following error:
/usr/local/jruby-1.1RC1/lib/ruby/gems/1.8/gems/activerecord-jdbc-adapter-0.7.1/lib/active_record/connection_adapters/jdbc_adapter.rb:303:in
`initialize': The driver encountered an error: java.lang.NullPointerException:

from ./rowcounts.rb:13
The script I am running is this:
require 'rubygems'
gem 'activerecord-jdbc-adapter'
require 'jdbc_adapter'
require 'active_record'
ActiveRecord::Base.establish_connection(
:adapter => 'jdbc',
:driver => 'COM.ibm.db2.jdbc.app.DB2Driver',
:url => 'jdbc:db2:OSU',
:username => 'db2inst1',
:password => 'db2admin'
)
conn = ActiveRecord::Base.connection
puts conn.active?
Under ruby 1.8.5 (2007-11-01 rev 4842) [sparc-jruby1.1b1],
activerecord-jdbc-adapter (0.7.1), i also error out with this message:
java.lang.NoSuchMethodError:
org.jruby.javasupport.JavaEmbedUtils.newObjectAdapter()Lorg/jruby/RubyObjectAdapter;
[snipped 730 line stack tace, see attached file for full stack trace]
It works as expected under ruby 1.8.5 (2007-11-01 rev 4842) [sparc-jruby1.1b1],
activerecord-jdbc-adapter (0.6)
