Weblogic 11 G : Altering default class loading - classloader

Question

I have one query regarding Weblogic server 11 G class loading infrastructure.
Lets say I have two application jars named A.jar and B.jar loaded in classpath during server start up.
Both jar contains class say LoadMe.class and sever loads LoadMe.class from jar A.jar by default.
Now I want to alter above default behavior and want to load that class from B.jar instead of A.jar.
How can I do that?
Any help will be appreciated.

Answer 1

Whenever you use LoadMe class for the first time the ClassLoader will try to resolve the dependency using the CLASSPATH.
Now if you have to load the class from B.jar, then you will have to explicitly place path to that jar first and A.jar second in the CLASSPATH. So the ClassLoader will pick the class from B.jar first.
Try this link for more on ClassLoaders
Read this and change the classpath and the problem should be solved

UPDATE:
System.out.println("Classpath dependency for LoadClass: ");
URLClassLoader classLoader = (URLClassLoader)LoadMe.class.getClassLoader();
System.out.println(Arrays.toString(classLoader.getURLs()));
System.out.println("Classpath dependency for Context: ");
URLClassLoader classLoader1 = (URLClassLoader)Thread.currentThread().getContextClassLoader());
System.out.println(Arrays.toString(classLoader.getURLs()));
