n00b question on passing parameters to a webservice

Let us say I have a webservice method:
api_method :login, :expects =>
[:name=>:string, :password=>:string],  :returns => [:int]

defined as:

def login(name, password)

   #do something here and returns an int
end

how do exacly pass it the two parameters from the client?
I tried:

- @ws_client.login(''user'', ''mypwd'')

- @ws_client.login({:name =>''user'',
:password=>''mypwd''})

- @ws_client.login([''a'',''b''])

No matte what, I always get:
"wrong number of arguments (1 for 2)"

When edit the method to accept just one parameter, and call it with:
 @ws_client.login(''user'')
everything runs fine.

I''m sure I''m missing something _very_ obvious. Please help....

Thanks in advance

 From one n00b to another ;)

Have you tried this?

@ws_client.login(:name =>''user'',
:password=>''mypwd'')

I would have thought this would have worked (I don''t know why it
doesn''t):

@ws_client.login(''user'', ''mypwd'')

..but these won''t work :

@ws_client.login({:name =>''user'',
:password=>''mypwd''})

@ws_client.login([''a'',''b''])

..because Ruby sees the Hash and Array as a single argument

then you should be able to just do @ws_client.login(''user'',
''password'')

Re: n00b question on passing parameters to a webservice

Ok, the lucky combination was:

:expects => [{:name => :string}, {:password => :string}] #in the
service definition

@ws_client.login({:name =>''user'',
:password=>''mypwd''}) # in the method
call.

Now it works beautifully.
Thanks a lot, everyone!
