unable to run the application when running from Junit

I am working on developing scripts for a banking application using Selenium on Firefox, the application take cookies and will store the cookies, when i run the application manually and via using selenium IDE in firefox it works fine Now i am converting the selenium commands into JUNIT and when i run (here in the background selenium server.jar开发者_运维技巧 is running,)via eclipse the application launches in firefox but creates a seperate profile and in that profile there are no cookies and so my application fails,

Is there any way where i can run the script using Junit and use the firefox browser where it uses the cookies it stores and run the script,

Looking for a positive response,

Regards, Sairam
