Hi ,
I have some basic doubts .
what is the difference between dispatcher servlet and application context.xml ?
If we are using Spring MVC, then along with handler mappings, can we declare Spring support beans (Dao,session ...)also in Dispatcher Servlet ?
which one is needed for applications ? Spring allows only one (either dispatcher or applicationcontext) per application ?

Hi Indu,
1. As you a aware of Dispatcher-servlet.xml is for the spring handler mapping and applicationContext.xml is for the application beans such as the DAO, sessions.. 2. Yes, you can declare spring support beans in dispatcher-servlet.xml, but its not a good practice though.. 3. Generally, if you use spring MVC, you need dispatcher-servlet.xml. If the application needs DAO access, mail sessions, then they can be defined in applicationContext.xml.. 4. No, spring does not limit to one per application, you can have as many xml as you want and initailize using a contextloaderlistener..
