I am developing a Java application to generate reports from .jasper report files created

  • 0

I am developing a Java application to generate reports from “.jasper” report files created in iReports. When the reports are generated in PDF, I would like to retain column labels and pagination info on each individual page. However, when exported as an excel spreadsheet or pure HTML, I only want the column headers once. Can anyone suggest settings that I can pass programmatically in Java to the Jasper API to handle this?

    There are a couple settings you need to setup in the exporter to export it as one page:

    reportExporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE); 
reportExporter.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.FALSE);

    Now this only gets you part of the way. Since it will still print the page header and page footer once each. You need to add a boolean parameter to the report that indicates whether or not to print those bands. You would set this in the printWhenExpression for the bands.
