changes in property file not affecting the exe--its very urgent

I have created a swing application. I have a property file which contains database connection string and other details. i created setup file using Advance Installer where i have packaged jre,jar,lib. inside lib i have a folder called config which has the property file.

after installing and creating exe now i have changed the key value of the property file (ie., ip address where the database resides). if i run the exe it is not reflecting the changes made in property file instead it is retrieving the datas from the database which resides in the old ip address.

whats is the solution for this. its very urgent.

thanks
