I put the .jar file in my "lib" folder under the project, but how can I use the DejaVu Sans font in my reports? Or maybe there's a better solution? Also, when I'm generating the report via web application, do I need to put the .jar somewhere on the server and if yes, where?

This is the .jar file in the project build path:

And this is my font list under the same project:

Shouldn't this list be filled with the custom fonts?
