My objective was to create a 5-page invoice file in PDF format.  Each page has different layout so it’s not possible to write all of them in just one file.  What I did is I created 5 JRXML file with multiple sub-reports.  I Used iReport-3.7.0 to create the jrxml files and compile into .jasper files.  This way, I don’t have to recompile the jrxml files into jasper files.

Another issue that was solved here was the page number issue.  You’ll notice that every jasper page will have its own page number and will start with “page 1”.  To solve that, we created an input parameter called “paramRunningTotal” and was used to set the initial page number of the succeeding page.  To get the total number of pages created by the previous page, you’ll have to get the return value of the previous page and pass that value unto the next page.  (Sample code below)

int runningTotal = 0;

t00  = (JasperPrint) JRLoader.loadObject(“/rbs/ireports/jrprint/invoicemainfile.jrprint”);
runningTotal += t00.getPages().size();

params.put(“paramRunningTotal”, new Integer(runningTotal));

I followed the sample pseudo code that I got from the net and you can also read that here:  How To Create Multiple Page Report In Jasper Reports

I’ll be sharing you the source code and you can download it from here.  If in case you encounter dependency issues such as “RBS-Importer”  just remove them.  You don’t need those dependencies.  I used Eclipse IDE version 3.3.2 (Europa) and Java 1.6

For those who doesn’t want to download the whole project and just want to get the source code, see the code below.  I’ve been searching for this kind of sample code before but only got a pseudo code.  I really hope this helps you on your jasper report tasks.

If you need assistance on the JRXML files, just contact me via Email or chat with me via Yahoo Messenger: rqniefes@yahoo.com
