如何在 iReport Designer 5.6.0 中使用 json 数据文件

Question

I had just downloaded iReport 5.6.0 . But unable to load any JSON file parameters on top of the report.

I didn't find any good help online related with this. I find some help from the url as below:-

http://community.jaspersoft.com/wiki/how-query-file-based-json-datasource

But from the above steps I didn't know where to write query in "report query" and to manually create fields, matching names of our json data.

Please help to load data from JSON datasource.

A little bit late, but here are directtions.

1) Click Report Datasource button in iReport Designer:

2) Click "New", select "JSON datasource, click "Next"

3) Give it Name, browse to a json file, click "Test" to check:

json.txt:

[
{ "id": 123, "name": "abc" },
{ "id": 456, "name": "def" }
]

4) Add fields manually, use proper types and put onto the report page:

5) Generate preview:
