I am installing XI with NW07. I had an ERP2005 server here with ABAP only. I installed Java add in to it with usage type PI.
Now I tried to install J2ee adapter engine. It showed if i want to run a new installation or continue the old one.
So what to do here. Do I need to install J2ee adapter engine too for XI.
This is my 1st experience with XI installation. So do not much.
