How to merge two pdf documents into a single report in JasperReports?

Question

I am new to JasperReports. I can create a simple PDF document with Javabean datasource. In my project I have created two separate pdf document with separate javabean datasource. Now I want to merge both documents into a single document. Can anyone tell me how to merge both documents into single document using JasperReports?

Answer 1

unfortunately the solution is build a sub report and use the 2 different DataSource or what ever connection you used

but there is an easy way to get over with this question :D just simple no new reports ..... Voilà

ok lets do it

JasperPrint jp1 = JasperFillManager.fillReport(url.openStream(), parameters,
                    new JRBeanCollectionDataSource(inspBean));
JasperPrint jp2 = JasperFillManager.fillReport(url.openStream(), parameters,
                    new JRBeanCollectionDataSource(inspBean));

ok we have over 2 records ..lets take our first record jp1 and add jp2 content into it

List pages = jp2 .getPages();
for (int j = 0; j < pages.size(); j++) {
    JRPrintPage object = (JRPrintPage)pages.get(j);
    jp1.addPage(object);

}
JasperViewer.viewReport(jp1,false);

This work like a charm .. with couple of loops you can merge any number of report together .. without creating new reports
