Class JRXlsDataSource

java.lang.Object

net.sf.jasperreports.engine.data.JRAbstractTextDataSource

net.sf.jasperreports.engine.data.AbstractXlsDataSource

net.sf.jasperreports.engine.data.JRXlsDataSource

All Implemented Interfaces:

JRDataSource, JRRewindableDataSource

Deprecated.

Replaced by XlsDataSource.

public class JRXlsDataSource
extends AbstractXlsDataSource

This data source implementation reads an XLS stream.

The default naming convention is to name report fields COLUMN_x and map each column with the field found at index x in each row (these indices start with 0). To avoid this situation, users can either specify a collection of column names or set a flag to read the column names from the first row of the CSV file.
