All SAP NetWeaver components (example, PI, CE) run on top of the SAP Web Application Server.

The following three usage types are possible with SAP Web Application Server:

SAP WebAS ABAP (ABAP only)
SAP WebAS Java (Java only)
SAP WebAS Add-In (ABAP and Java)

Depending on the SAP NetWeaver component to be installed, the Web Application Server installation type is determined. For example, SAP NetWeaver PI requires SAP WebAS Add-In (ABAP + Java) usage type.
