jasper: listing all key-values pairs of a collection
In jasper I have to print a collection without knowing in advance the keys, because they are programmatic and can change over time. Let me do an example of this list:
- formData[0]={addictions=1, workout=0, allergies=1, selfSufficiency=0}
- formData[1]={gastricNose=1, weightChange=1, diet=XXXX}
- [...]
- formData[12]={dailyAmount=12, latestDate={type=date, value=1542582000000}, ostomy=1, ostomyType=AA, ostomyBag=BB}
How can I print a list of all these keys/values so that they get all listed properly like this? I can already print these objects raw in a list but they obviously look pretty much like the example I wrote above, while instead I need jasper to cycle through each of the elements by itself and retrieve the keys and the value for each element.
This is what I'm trying to print:
- addictions: 1
- workout: 0
[...]
gastricNose: 1
- weightChange: 1
[...]
dailyAmount: 12
- latestDate: 18/11/2018
- [...]
In all posts I've looked into I'm required to know at least the name of the keys, but in my case I can't. And I cannot modify the data source structure either (for instance formatting the collection to be {key:"addictions",value:"1"} can't do that).
Thanks for your hints

One way is to create a method in java that takes the json which return a JRDatasource, hence you call this from jasper.

Do you mean a java class embedded somehow in jaspersoft studio, then built all together?

Yes exactly a class that supply the datasource you need

The existing backend application is already feeding the report with this data and I cannot change it. I can only twiddle with jaspersoft studio. Unless there is a way to pack a java class into a jasper report to "modify" the incoming datasource that being almost a total jasper noob I'm not aware of.
