Hello all. I have tow report in my application; I use, for each report, the follow: JasperPrint jp= JasperFillManager.fillReport( this.jasperFilePath, this.parameters, new JRBeanArrayDataSource( this.vectorBeans ) ); Now, I need insert those reports ( as subreports ) into a master report; I find tutorials where subreports uses SQL queries, but I use the JRBeanArrayDataSource object. How I can do it?. Thank you, in advance. Code:JasperPrint jp= JasperFillManager.fillReport( this.jasperFilePath, this.parameters, new JRBeanArrayDataSource( this.vectorBeans ) );
