Re: JSON Limitations using IWS

I tried IWS as part of a JSON restful web service POC but rejected in
favour of a combination of apache and the YAJL parser.

Reason being that you have to specify all the fields on each call and
ordered to match the data structure whether you actually want them or
not.

Apache/YAJL requires more knowledge but you get better control.

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.
