Example of rendering a report with Java and Json?

I'm a bit lost on how to correctly initialize a report file with a json-datasource in java, and then getting it to render correctly.
I have a mrt-File and a json-File, those both work together fine, wenn looking at them in the designer.
But trying to do something like the following ends in a NullPointerException
Code: Select all
StiReport report = StiSerializeManager.deserializeReport(new File("report/Selection.mrt"));
StiJsonDatabase jsonDb = new StiJsonDatabase("Data", "report/data.json");
StiDatabaseCollection coll = new StiDatabaseCollection();
coll.add(jsonDb);
report.dictionary.setDatabases(coll);
report.setJsonReport(true);
report.render();
Is there somewhere where I could find an example on how to render a report with a json-File through the Java-Libraries (2016.2)?
Thanks a lot in advance

could solve the problem myself, the problem was in the way the json was built

Unfortunately I really do have another problem
:
The json for the data now is built up as suggested in another thread with every object as an array, so that it can turned into a table. Now I have a groupheader, that takes its data from a table with relationships, but where I want to put as well some of the same data into for every grouped entry.
This once again seems to work fine in the designer (.NET 2016.2), but when rendering the report through java (see code in first post) I get a parse-error for a null-value.
I have some demo data attached, the problem lies within the PartialOffers.
I have already tried calling those values with PartialOffers.DataTable.Rows[0]["columnName"], but then the report does throw errors.

Thanks a lot for looking into it.
Do you have a timeframe when that pre-release build will be available?
