Hi,

I would like to know while instantiating  beanfactory why we use only classpathxmlapplicationcontext not other ones. What we use for ApplicationContext. What are the differences, similarities, uses of these two. Any ideas, suggestions, sample code, resources, links highly appreciated. Thanks in advance

ApplicationContext context extends beanfactory only ... so you can use application context ..

>>>>>>>Tehn why we use BeanFactory. please advise

Actult its mainly used for wiring concept . In your application you use only wiring then u go for beanfactory .

If you use applicationContext then it extends beanfactory only so both class memory will take here !
