RE: [Caution: Message contains Redirect URL Content] Re: JSON Limitations using IWS

Yes, you can omit fields, you just can't send something that is not expected.

Also, the order in the JSON document is not important.

I do not think it is true that you have to specify all the fields. You are able to omit fields.

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?
