Jquery Dialog- Included JSP files loosing its .js file

HI, I am implementing jquery dialog into my application but the problem was when i am loosing the inluded .js file from the jsp which i am opening in the diialog box. 
 "<script type="text/javascript" src="../ext3/<Some script>.js"></script>:"

Can you please suggest why is that happening and what should be the possible solution for that?
