There should be no issue integrating this in Java. You just call your main report as you would call any report.

Set "Subreport Expression" to the subreport's filename (with .jasper extension). E.g. "mysubreport.jasper" (between "" signs), and choose java.lang.String as Subreport Expression Class.

 

Now you need to put your subreport jasper file to the classpath of your web application (e.g. into WEB-INF/classes), and nothing else needs to be done, when you generate the master report, it will be found.

 

Another practical approach is that you set Subreport Expression Class to e.g. net.sf.jasperreports.engine.JasperReport, and its value is a parameter (of the same type). This parameter gets its value just like the other parameters: so you can instantiate your subreport in your java code (just like you do with your master report) as a net.sf.jasperreports.engine.JasperReport object, and add it to the parameters.

 

HTH,
