8)When i go to C:\rubyInstall\lib\ruby\site_ruby\1.8\db2, i can see the
file db2cli.rb
Also when i got to
C:\rubyInstall\lib\ruby\site_ruby\1.8\i386-msvcrt\db2, i could see
db2cli.so file

So far everything looked OK, but when i try to run the sample program
for the connectivity i'm getting this error!!.. tried all options, but
could not get away. Can any body please give a hand to me to resolve
this..

Sample.rb
******************************************************************************
require 'dbi'

  DBI.connect('dbi:DB2:RESERVDB', 'db2admin', 'db2admin') do |dbh|
    p dbh.select_all('SELECT * FROM XMLFLIGHTTB')
  end

Also, when i try to run the samples directory from the ruby-db2-0.4.4,
it gives me the below error, as undefined method - createConnection? Any
reason???? pl

C:\rubyInstall\lib\ruby\site_ruby\1.8>test2
C:/rubyInstall/lib/ruby/site_ruby/1.8/test2.rb:5: undefined method
`createConnec
tion' for #<DB2::Environment:0x2c8baf0 @handle_type=1, @handle=1>
(NoMethodError
)


Thank You
Dinesh
