Solution 1

It's on the classpath so it should be the resource should be precedded with a forward slash i.e. /second.fxml

That is assuming it is not in a package. Make sure your build system is also copying it to the output directory along with your class files.

Solution 2

"Ah, then you need /demo/second.fxml as the resource path. Saying that, I am confused why the error message says sucess.fxml and not second.fxml. If the above suggestion doesn't work can you post the fxml? – Andy Till"

This comment from Andy Till is the answer to the question. Thanks Andy. You solved my problem :) Thumbs up !!!

Include the package name. For ex:

/package_name/fxml_file_name.fxml

all the file are in the same directory

[Sergey Grinev]

yep, second one is a common issue. If you are in Netbeans run Clean and Build to ensure that.

Its being included in the package.. I checcked using winrar.. Error exists even after changing it to /second.fxml

[Andy Till]

Is it in the root of jar is it it another directory?

[Vinod CG]

There is a package with name demo and all the files are inside it
