Java EE (Java Enterprise Edition) General Discussion

Hi,
I've recently downloaded JasperReports 0.6.5 and I am exploring it for a while.
I would like to get certain clarifications for the following.

What are the roles of:

a) jrxml file
b) jrpxml file
c) jrprint file
d) jasper file

From my knowledge of understanding, jrxml is a kind of template in xml format used by JasperReports.

When I compile a .jrxml file by JasperCompileManager.compileReportToFile("xyz.jrxml"), then it is converted into .jasper file.

In the demo/samples code, I see several standalone programs for generating various types of reports.

I noticed that programs either take .jasper file or .jrprint file as input to generate reports.

Sometimes when I try to use .jasper, it throws exception and in this forums I noted that I should use .jrprint instead.

I am confused on when to use .jasper and .jrprint files? Also help me out how can I create .jrprint file.


Very finally, what is the role of .jrpxml file?

Thanks in advance.
