Re: JSON Limitations using IWS

Hi Troy,

It is not currently possible to ignore properties. Maybe an RFE[1] is in
order.

There is no limit as far as I know to the number of fields in a structure
or nested structure. There is a limit to number of parameters (for
programs, I believe it is 255; for procedures, I believe it is 7).

I have created a RESTful web service using the IWS wizard with JSON
as an input parameter.
It works fine when the JSON is small as in the example provided here:

https://www.ibm.com/developerworks/ibmi/library/i-
rest-web-services-server3/

However, I need to accept a larger file with hundreds of JSON field
names and it fails because all the fields are not declared in my RPG
program data structure.

This is the error -

org.codehaus.jackson.map.exc.UnrecognizedPropertyException

Is it possible to set something like this?: @JsonIgnoreProperties
(ignoreUnknown = true) as described here: https://stackoverflow.com/
questions/4486787/jackson-with-json-unrecognized-field-not-marked-
as-ignorable/7546047#7546047 , or do I need to declare every field name?

Is there a limit on the number of field names that IWS will allow
for a JSON file?

Cheers, Troy.
