Adapters Running in the J2EE Adapter Engine 

Many adapters can be deployed in the central Adapter Engine and in non-central Adapter Engines.

Adapter Engines always forward incoming requests to the Integration Server by using an internal HTTP connection and service user PIAFUSER (parameter com.sap.aii.adapterframework.serviceuser.* of the exchange profile) for execution.

Outgoing XI messages are always forwarded to the Adapter Engine by using an internal HTTP connection and service user PIISUSER (parameter com.sap.aii.integrationserver.serviceuser.* of the exchange profile) for execution.

SAP recommends that you secure these connections by HTTPS as described under HTTP and SSL.
