Hello is there any restriction in where you can access your datasource?
I mean does it have to be from servlet or jsp or can any class access it?

Any class can access a datasource. You can create a Java bean that encapsulates your business logic, and then the servlet (or JSP) can access that bean.

In fact, I believe that the preferred architecture is to use JSPs mainly for doing UI stuff, with either no or minimal Java logic. The servlet then acts as a traffic cop, creating the appropriate beans based on the request, and calling the appropriate JSP for displaying the results.
 
It is sorta covered in the JavaRanch Style Guide.
