Question

For test purpose I need to substitute .jar file with my own.
Does it possible set test.jar (the same name) previous on other test.jar?
Will classloader load only first find jar?
Thanks.

Answer 1

The Java interpreter will look for classes in the directories in the order they appear in the class path variable.

Edit: So you can put you jar first in the classpath to overrider the existing jar.
