HI,
One suggestion is to look at your “SOAP action header” setting in your ports configuration. If you used the default bindings which were created when generating your schema, they are usually created wrapped within an operation.
Unless the send port within your orchestration’s operation matches the same name as the enclosing operation tag in the “SOAP action header” sending messages using the default setting will fail.
So to ensure that your send port works just supply a URL for the “SOAP action header” setting.
I hope this helps.
