jar / war / ear common spring dependency

Consider the scenario

abcd.ear containing

a.jar - spring enabled components
b.jar - spring enabled components
c.jar - spring enabled components
d.jar - spring enabled components

1.war
using spring components from a.jar, b.jar, c.jar, d.jar

2.war
using spring components from a.jar, b.jar, c.jar, d.jar

Question: how can we load the spring components of a.jar, b.jar, c.jar, d.jar once at osaEnt.ear level and use it across different web application context, instead of reloading those jar spring components individually at each war?

Looks like this article provides all necessary information for that.
