How to prevent calling jsp directly?

I want to block calling my jsp pages directly from web browser. I just map the urls on web.xml... Please give an idea.

For example:

I dont want mydomain.com/index.jsp

I want mydomain.com/index

Note:my jsps are placed in the root of my context. If needed i can change the place of them

null
