i have learned the ROR for one month. i have a small web service
program.

my program have some file divide into some folder:
in the apis folder:
  1. user_api.rb
  2. feedback_api.rb
in the model folders:
  3. user.rb
  4. feedback.rb
  5. user_service.rb
  6. feedback_service.rb
in the controllers folder
  7. sgs_controller

i have some problems with my service.
1. when i call my service via soap and wsdl as follow:

  wsdl = 'http://localhost:3000/sgs/wsdl'
    driver = SOAP::WSDLDriverFactory.new(wsdl).create_rpc_driver
#    @results = driver.public_methods.sort.join('<br>')

    @results = driver.getUserNameById(1)

then i get a error as image file.

2. in the sgs_controller, i was called web_service two times for user
service and feedback service as follow:
   web_service :user, UserService.new
   web_service :feedback, FeedbackService.new
but i can't see methods of feedback service in driver. i don't know why
???

Please help me to resolve my problems.
