Primefaces FileUpload Get File Extension

Question

I'm using the primefaces fileUpload component and then I inspect the FileUploadEvent.getFile but I don't see a way to reliably get the extension. Any ideas?

Answer 1

getFile() returns an org.primefaces.model.UploadedFile object which has a method getFileName to return the file name. Then you can get the extension from the filename.

UploadedFile tfile = event.getFile();
String str = tfile.getFileName();
String ext = str.substring(str.lastIndexOf('.'), str.length());
