将maven创建的war文件部署到glassfish服务器，确定类路径的顺序？

Question

Setup

I have a maven project which creates a war file, I then deploy the war file to a glassfish server (3.1).

My Manifest is default one with just the basic info, but I've also tried maven-war-plugin to add classpath to the Manifest. From my understanding of that plugin it should only help me determine libs outside my web-inf/lib scope.

Problem

In my war file I have two dependencies which both contain the same class but two different version of that class, so I need to specify my Glassfish Archive class loader to load them in a certain order. Now I'm completely lost as how to do this, which leads me to my questions.

Questions

1. Is it possible to use the Manifest file to force Glassfish to use a specific classpath?
2. How does Glassfish determine in which order it loads the jar files in WEB-INF/lib?
3. Is it possible to tell Glassfish how to specify the classpath in some other way?
4. If not, is it possible to affect the order Glassfish loads the jar files in WEB-INF/lib?

Answer 1

(I don't have privileges to comment in SO, hence the answer) The following link describes one way of managing the order of class loading.However, as others have rightly pointed out, what you are trying to achieve is not good at all.
