Number of flags is a column name in database. This column is having null value in the table. I am executing the query in jrxml itself by passing a connection object in the fillReport method of Jasper.
A pdf report is generated properly but the column value is displayed as null,null... for 20 times, since there are 20 rows in the table.
How to chaeck for the null value and replace it by some other value, say, an "-" so that pdf report doesn't have the value displayed as null, if data is empty in the database table by changing the jrxml report template?
I am using Jasper version 2.0.3. jrxml template created using iReport.
