Rajeev,
 
you could use String[] getAliases(String name) throws
NoSuchBeanDefinitionException in BeanFactory and catch
NoSuchBeanDefinitionException. If caught, then bean does not exist in the
factory.

registry?


Is there an easy way to determine if a certain bean exists in the
beanFactory?  I know one can use the getBean(name) to determine that, but it
seems an expensive call,  especially, if there are bean post processors
associated with it.  Don't you think having a function like    boolean
containsBean(String beanName) in a beanFactory class would be useful here?
