/**
 * Utility for looking up factories from Spring. All factories are made avaiable
 * under the bean factory SPRING_BEAN_FACTORY and can be looked up using the
 * keys BEAN_XXX through standard Spring mechanisms. Rampart-common is packaged
 * with a default beanRefContext.xml file, which contains default implementations
 * for RequestContextFactory, Audit etc. To change the implementation, create a
 * new BEAN_CONTEXT xml file and make sure it precedes rampart-common.jar in the
 * classpath. Spring will then load your implementation instead.
