Java and ABAP Stack

[Former Member]

Hi All,

I am still not clear about role/function of java and abap stack in XI.

Can anybody explain?

Sireesha,

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::

Hi Sireesha,

XI is installed on WAS which has both ABAP engine and Java Engine.

<u>Java Stack</u>

The J2EE stack contains the Adapter Engine, our mapping programs will get executed in Java stack only. Integration builder, Adapter engine and RWB will be installed on Java engine.

<u>ABAP Stack</u>

Integration engine, BPM engine will be installed on ABAP stack.

Cheers,

venu
