Question

I’ve got a question on how to add a jar file with code.

The situation is that I want to allow the customers to choose themselves, which database should be connected. Therefore, I’d like to give them the opportunity to load a custoom *.jar into the running software (similar to Add external library in eclipse).

Is there a way how I can manage that? I was trying kind of

import System.getProperty("java.io.tmpdir") + "\\dbdriver.jar";

java.io.tmpdir\dbdriver.jar would be the file, where custom jar-library-imports will be stored by my code. But eclipse didn’t seem to like it.

Do you have any idea?

You’ll need to read up on Classloaders and Reflection in order to get an understanding of how this works.
