500 error when calling webservice through rhosync/rhodes - service

Question

I am trying to call a web service in rhosync application.rb, I see a 500 error response in rhosync console .. and 'server returned an error' in BB simulator .. :(
Some info about my setup -
I have created a rhodes app that connects to a rhosync app when user enters user name and password and clicks on "login". I am calling this webservice through "authenticate" method of application.rb of the rhosync application ..
def authenticate(username,password,session)
Rho::AsyncHttp.get(:url => 'http://mywebserviceURL',:callback => (url_for :action => :httpget_callback),:callback_param => "" )
end
UPDATE
Instead of http:async, I tried consuming a soap based webservice and it worked just fine .. here is code if anyone cones here in search of a sample.. in application.rb of rhosync app
require "soap/rpc/driver"
class Application < Rhosync::Base
class << self
def authenticate(username,password,session)
driver = SOAP::RPC::Driver.new('http://webserviceurl')
driver.add_method('authenticate', 'username', 'password')
ret=driver.authenticate(username,password)
if ret=="Success" then
true
else
false
end
end
end
Application.initializer(ROOT_PATH)

Answer 1

You can typically find the problem if you crank up your log. Edit rhoconfig.txt in your app
set these properties -
# Rhodes runtime properties
MinSeverity = 1
LogToOutput = 1
LogCategories = *
ExcludeLogCategories =
then try again and watch the terminal output. Feel free to post the log back and I'll take a look.
You also might want to echo out puts the mywebserviceURL if you're using that as a variable, I trust you just changed that for the post here. Can you access the webservice if you hit it with a browser?

require "soap/rpc/driver"
class Application < Rhosync::Base
class << self
def authenticate(username,password,session)
driver = SOAP::RPC::Driver.new('http://webserviceurl')
driver.add_method('authenticate', 'username', 'password')
ret=driver.authenticate(username,password)
if ret=="Success" then
true
else
false
end
end
end
Application.initializer(ROOT_PATH)
in this what is done in add_method and authenticate method and where it to be written.
