How can I avoid the column name repeating in JRXML? Is there any attribute for avoiding having the column header in each page when generating a report using JRXML and Jasper?
If the header will always be on a specific page (e.g. the first page), you can add
<printWhenExpression><![CDATA[$V{PAGE_NUMBER}==1]]></printWhenExpression>
to the band, which will make it only print on page 1. PAGE_NUMBER
is an inbuilt variable that is automatically incremented as the report is generated.
