How can i use two JRBeanArrayDataSource in a single report in iReport?

[vamsikrishna]

Hi

Am passing two sets of JRBeanArrayDataSource s from java to jasper. Am sending datasources as parameters

parameters.put("ds",datasource);

parameters.put("ds1",datasource1);

Here datasource and datasource1 are of type JRBeanArrayDataSource .In iReport am taking two parameters with the same name's  ds and ds1 with Parameterclass as "net.sf.jasperreports.engine.data.JRBeanArrayDataSource". When i export data am getting null values in report.

What might be the problem in this.Am using two datasources for the same report. Is that the problem?

Please provide me the solution for this. I need two datasources for the same report. How can i do that.

Thanks in advance
