How to fill a list with json array of strings?

0
 

Hello! There are many questions about json arrays here, but I didn't find any answer working for me. Please, help.

I have a simple json:

{
    "header" : "some header",
    "footer" : "some footer",
    "strings": [
                    "foo",
                    "bar",
                    "baz"
                ]
}

and a simple report:

                <textFieldExpression><![CDATA[$F{footer}]]></textFieldExpression>
            </textField>
        </band>
    </pageFooter>
</jasperReport>

But when I print it - only the first element of an array appears:

Perhaps, something is wrong with the pattern strings.*

What am I doing wrong?
