NWDI Configuration prerequisite components

Dear experts,

I am trying to configure the NWDI for a JAVA stack (PO) with SAP Netweaver 7.40.

I need to download the deploy components in order to deploy them through the SUM since during the installation it wasn’t done.

My understand is that I need to download 4 packages

DI_CMS

DI_CBS

DI_DTR

??????

I need your help in order to confirm:

1. For this version these are the components that I need?
2. What is the 4th components that I need (if apply)
3. What is the technical name to find the component’s in SAP market place  because I  couldn’t find them.

Best Regards,

DanielO
