It isn't clear from your description, but when you're using the .jic you also need to have added the EPCS Flash Controller and have configured the NIOS to boot from the EPCS bootloader. In other words, just programming the .jic file isn't enough to make your software get copied to SDRAM after reset. In your shoes, I would revisit the .jic method after having changed your hardware to use the EPCS boot method.
Whats happening here is that the EPCS ROM bootloader is just a simple program for the NIOS that knows how to point back to the EPCS flash and copy the contents after the hardware section to the locations encoded in the .jic
Here are some Altera links, AN736 in particular:

Thank you ted.
What is not clear from my description?
I already have EPCS Flash Controller in my Nios.
I have already configure the Nios to boot from the EPCS Memory.a
But I don't know about bootloader program. It is not described in the formal document below :(
