communication between abap stack and java stack

[Former Member]

Hi

When JAVA stack communicates with ABAP stack it does it thru JCO.

Could you please tell me during operation of XI how they communicate with each other ?? I mean during the passing of data from sender systemt to receiver system will they communicate with each other ??

Thanks

Hi

Tha ABAP stack consists of the Integration Server which in turn contains your Integration Engine and Business Process Engine.

The J2EE stack contains the Adapter Engine and your IR and ID run on the J2EE engine.

Most of XI pipelines happens in the ABAP stack.

All messsages picked by the Adapter Framework running on the J2EE engine are passed to the Integration Engine, which does the routing. The mapping program again gets executed on the Java stack and the rest of the pipeline servies are executed again on the ABAP stack and so on.

please go through links::

yes the Communication between ABAP and Java Stack is done via JCO.

The connections used for this are, the TCP Ip connections in SM59

1. AI_RUNTIME_JCOSERVER

2. AI_DIRECTORY_JCOSERVER.
