Problem using web services (SOAP)

[StefaniaS]

Hello,
I'm tring to use web services of OTRS, in order to integrate to another system, but I'm facing a problem.
I want to use OTRS as a requester, I followed the admin manual and set:
- the Endpoint as the location of the remote system wsdl: 'http://host:port/rpc/soap/system-v2?wsdl'
- the Namespace as: 'http://www.w3.org/2001/XMLSchema/Ticket' (but I'm not sure of this).
- a user and a password to auth to the remote system

But when i want to create a Invoker in the section OTRS Requester I don't have the chance to do it, because the dropdown list is empty(I'm sure that the rempote system provode ws becasue I'm already using them).

Where I am wrong?

Thanks

did you create (developed) the code for the interface to the other system? OTRS does not provide a generic invoker just a generic provider

Thanks, I've missed this step.
Do you know if there is a template to develop this interface?

Thanks
