It seems spring reads projectname-servlet.xml.It does not read applicationContext.xml even if it is mentioned in web.xml .
How does it work?I am totally confused.

Can you post the relevant part(s) of the web.xml? Where's your applicationContext.xml is located in the deployed application? Is this happens to any other annotated beans or only for this?

It is sorta covered in the JavaRanch Style Guide.
