Thread: Java 1.4 *IE7.0

I have Java Web Start and IE 6.0.The application run's fine good.This is default setting.Now i tested the application using IE 7.0.It fails "Error opening File c:\BatchLoad.txt".Does it any security problem or properties i have to set .
Thanks

I was researching ,i found that IE 7 has more restriction abt file.Does it mean i may have to use specific location or sanbox to save my file which i use it in application.
I am gussing.
