I have a question regarding sub-datasets. I am new to the Jasper reports and working on the integration with myu application. The Fill manager requires either a JRResultSetDataSource or a connection datasource to be passed to it. However this is only for the main report. My question is how do I pass a JRResultSetDataSource to the subdataset for the chart. The chart that I want to display comes from a different query? Is it possible? I do not want to put in the query in the jrxml file for it to get the data. Please help. Thanks, Sumeet
