10.4. Considerations for Generated REST Services

If you defined a procedure that returns a XML content, then REST service call must be called with "accepts" HTTP header of "application/xml". Also, if you defined a procedure that returns a JSON content and PRODUCES property is defined "json" then HTTP client call must include the "accepts" header of "application/json". In the situations where "accepts" header is missing, and only one procedure is defined with unique path, that procedure will be invoked. If there are multiple procedures with same URI path, for example one generating XML and another generating JSON content, then "accepts" header directs the REST engine as to which procedure will be invoked to get the results. A wrong "accepts" header will result in error.
