Accessing a file

Hi,

I am trying to access a file which is stored within my project itself.

I wouold want to change the contents of the file at runtime. For this i have to access the file .

To access the file i dont want to give an absolute path when it is deployed in the server. How can i get a relative path.

Assuming i am storing this file in the lib folder of the project how will i access it without the absolute path

(I dont want to use http alias!)

Any help is appreciated..
