Understood – this is exactly what I tried.
It seems that if the example.Example is in the \launching classpath\ – i.e. \.\ or root, it works.

However, If i place the example/Example somewhere else, and then use:

= new URL(\file:/Location off class path\);

The code breaks.

Do you have an explanation for this behavior?

Thank you.

“example” is a Java package and is part of the class name. When URLClassLoader looks for example.Example it really searches all classpath URLs for “example/Example.class”.

If you put the class in a different directory, the code breaks with ClassNotFoundException, even if you modify the URL generation code.

Why is that?

//cp = new URL(loc.substring(0, loc.length() – resName.length()));
cp = new URL(“file:/D:/temp”);
