setError

setError(errorCode: Integer;
         errorItem: String;
         errorText: String);

The setError method of the JadeWebService class specifies the error code, item, and text of the SOAP error. This generates a SOAP fault to be returned to the client.

If you do not want to return a SOAP fault, you must handle it differently (for example, by sending a message back as part of your response).
