set the dataset to jrxml template file

[Annapurna-Kotte]

Hi Team,
Am using FastReportBuilder to build the dynamic reports.
And I have the template file (jrxml) and it has the its own fileds.
In our Application I have used method objFastReportBuilder.setTemplateFile("template path", true, true, true,true).

But in generated pdf file report shows the null values instead of actual filed value which defined in jrxml file.

Can anyone help me to how to send the data to the template file and how the Jrxml fileds are get evaluated.
If you provide any example with this option objFastReportBuilder.setTemplateFile("template path", true, true, true,true), that will be very helpful
