servlet load

[rmatilda]

Hi,
I am not sure if this is a Spring related doubt but i would be glad if anyone could help!
I am building an application where in i have some set of objects described in an xml config file. I have a program that reads this config file and creates an in-memory datastructure of the set of objects. I need to load this data structure when my application starts. I understand that i need to configure my servlet for doing this. My doubt is how should i configure my servlet?
What changes do i make in my web.xml?
I am using Spring and Hibernate in my application.

Thanks
