Code snippet to create a JasperPrint object from a collection datasource.

JasperPrint jp = new JasperPrint();
String reportPath = "/HD/jasper/mypath/myfile.jasper";

Map paramsMap = new HashMap();  //put whatever parameters you want to pass to report

//JR data source, populate with your collection
JRDataSource reportSource = new JRBeanCollectionDataSource( reportCollection );

jp = JasperFillManager.fillReport( reportPath, paramsMap, reportSource);

//Here you can use the PDF generator to make a PDF file out of the jp object. Then forward it to client
