[@TechTalksbyRanga]

Hey, I need to get json data from postman and need to insert that json to jasper report "Fields". How do I do that?

[@SwatechTalks]

are you calling any rest endpoint through postman?

[@TechTalksbyRanga]

Yes. Do I need to assign that postman json to variables?@@SwatechTalks

[@SwatechTalks]

not really.. see if you can call the endpoint through jasper and use the response

[@TechTalksbyRanga]

Do you have a video about this? Can I use any data adapter in jasper studio to create the jrxml file? I am stuck here since 3 days.@@SwatechTalks

[@SwatechTalks]

I dont have knowledge on jasper my friend.. but it should be possible to create a pipeline where you configure your jasper report to fetch data from rest endpoint and then put it in fields.. see if you have some sort of ETL in jasper

[@vishwjeetujgare7437]

What happens if we give int instead of string in json string and then try to deserialize it?

[@SwatechTalks]

what so ever datatype you pass, data should also be of the same type. if this is the case then it can deserialize else it would give type mismatch error

[@hitenarya4987]

Really liked this video

[@SwatechTalks]

[@zr60]

[@rajeevmishra3056]

If we are getting ResponseEntity response ….
Now how we can convert this response as json object

[@SwatechTalks]

There can be multiple ways.. one is using the google gson library. You can use below reference:
import com.google.gson.Gson;
ResponseEntity.ok(gson.toJson(""));

[@MemescapeHQ]

it was good but what about the objects and arrays in the JSON

[@WickedChild95]

Good video!

[@MrRahulKumarKandula]

Thanks for making me understand ObjectMapper. But why would you use the ObjectMapper class to write to a text file. You could have used any other writer class. Having said that thanks though.

[@SwatechTalks]

Thats just a example.. intention was to showcase object mapper use and not how to write data in file. Once you have your serialised version of json data you can do anything it .. here in this tutorial i wrote that in file. Thats it.. Thanks

[@MrRahulKumarKandula]

@@SwatechTalks Got it. Thanks again.
