To begin, complete the following steps:
Create a new interoperability-enabled namespace in your InterSystems IRIS® instance. Note that by default, the wizard located at System Administration > Configuration > Namespaces creates interoperability-enabled namespaces.
In your new namespace, create a new production. Name it Tutorial.ExampleProduction
Add the business operation Tutorial.ExampleOperation to the production. When adding the operation do not assign it any name. Allow the name of the operation to default to the classname. Note that you will need to write the code for this operation. See Creating Tutorial.ExampleOperation for instructions.
