This example follows the same pattern as the previous examples in this chapter. The
JRExporter
implementation needed to export to Excel is
net.sf.jasperreports.
engine.export.JExcelApiExporter
. Again, we set the report to export and the
output file name by setting the appropriate parameters on
JExcelApiExporter
.
