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

This is the easiest way is to use Coalesce() or NVL() function of database in your data-source query to restrict null data on your report.

But it depends on if you are allowed to change the datasource query or not. If not then you can go for other solutions provided in previous answers.
