Jrxml Cannot Read by Jar File

Question

I want to make report using Jasper , so I make .jrmxl file as resource. And I used this code to read that .jrxml :

JasperDesign jasperDesign = JasperManager.loadXmlDesign(new File(".").getAbsolutePath()+ "\\report\\reportPdf.jrxml");

That code ran well , and the report also appears .

My problem is when I export the program into .jar file , error appears , and It says "unknown resource" in line code above. So i am worried why this error is occuring ?

Answer 1

The report will now be an embedded resource, and not accessible by File .

You need to gain an URL , get an InputStream for it and call loadXmlDesign(InputStream) (or the non-deprecated variant - see the docs).
