Question

I have 2 versions of jar file (plugins1.0.jar and plugins2.0,jar) in same folder and trying to load Class from these jar files dynamically using URLClassloader.
I want to ensure that the class should be loaded from latest version of jar file.

How can i achieve this ?

Thanks in advance

Answer 1

You will need to construct your list of urls in such a way that plugins2.0.jar occurs before plugins1.0.jar. But generally it’s a bad idea as other classes may have conflicting versions loaded.

From Java docs

The URLs will be searched in the order
specified for classes and resources
after first searching in the parent
class loader.
