I try to use subreport using JasperSoft Studio but I get the exception below. It cannot find the subreport file although it is there.

Answer 1

Following Sharad's answer, if it still doesn't generate the file (which happened to me), you can try this:
Before previewing the report, you can try to compile it first. If you open your jrxml file (the one that includes the subreport), you may notice a little icon (a little file with some binary string) on the upper bar of your editor. Clicking this button should generate the file you're expecting.
I created a new answer because I wanted to add an image showing the button:
Notice that this may also work: clean the projects that contain the reports using "Project > Clean...". And then right click your project in the "Project Explorer" (usually on your left), and then click "Build Project".

Answer 2

Send the "SUBREPORT_DIR" parameter from the application that calls the report.
For example, in Java:
params.put("SUBREPORT_DIR", "reports/folder/");
Just point to the directory, not the file.
If you use Maven, set Maven resource tags properly in pom.xml

Answer 3

Try to give the subreport name in the subreport path like this :-
"D:\\JASPERREPORTS\\MyReports\\subreport.jasper"
Even .jasper file is not there just give the subreport.jasper it will automatically compile the subreport.jrxml file and generate the .jasper file.
