XI uses both java and ABAP stack.

SLD,IR,ID,RWB,AE are in JAVA stack

BPE,IE are in ABAP stack

Integration Server: It is the central and core part of XI used for processing the messages. It receives the message from Sender and applies the Logical routing, Technical Routing, Mapping and sends to the Receiver through communication channels developed in the integration directory. It has the following parts in it, used for specific purposes.

1. Integration Engine

2. BPE

3. Adapter Engine

Message Flow in IE-Pipeline steps

Receiver Identification, Interface Identification, Message Branch, Request Message Mapping, Outbound Binding, Call Adapter, Request Message Mapping

Message Flow in AE

Is XI uses ABAP/Java Engine

Xi requires Double stack

ABAP + JAVA Stacks

Bcoz some components are developed on JAVA

Some components are developed on ABAP Based.

JAVA:

Integration Builder

SLD

Adapter Engine

Runtime Workbench

ABAP:

BPE

Integration Engine

Integration Engine and the Integration server are sits on ABAP Stack. All the Execution of the IS part will be done on ABAP Stack. we can monitor the processed XML messages also in SXMB_MONI( ABAP Stack)

Adapter Engine will be there on JAVA Stack. All the IR, ID, SLD, RWB Application are developed on JAVA Stack, so thats why we need JAVA Webstart to run these Applications

All the Adapter related Errors we can see in RWB, Communication channel monitoring( Developed and sits on JAVA stack)

Idoc,XI,HTTP These adapters are working in Integration Engine
