JasperReports: default value instead of 'null'

Question

Is there any way to set a default value to a field in a report? I have a lot of String fields in a report and would like them to display \"0,00\" when they\'re null.

Answer 1

Supposing the field name is "value", in the "Text Field Expression", write:

($F{value} != null) ? $F{value} : "0.00"
