NW2004s Java Stack Installation

HI all,

Got a question about installing NW2004s Java Stack, hope someone can help me.

If I install NW2004s Java stack only, is it the system is Unicode already without any option in the installation process? So if the installation wizard promot to choose Kernel, it is ok to choose either Unicode or non-unicode Kernel DVD? Since I don't know why when I choose UC-Kernel DVD, it will prompt for incorrect label. However if I start the installation again and choose non-unicode Kernel, it will prompt for incorrect label again and I have to choose unicode Kernel DVD to proceed, seems there is some problems with the installer or anything else?

Thanks,

Kelvin
