Hi Ravi,

1)Where does HTTP runs

The HTTP Adapter runs on the ABAP Stack

2).What are the abap stack and java stack adapters?

Apart from IDOC and HTTP all other adapters reside on J2EE stack

3)How Adapter Engine works and Integration Engine works? and their importance?

The Adapter Engine provides connectivity to XI for non-Web AS Interfaces.it has built in capabilities for queuing,logging and tracing.

Integration engine provides the infrastructure required for local and central execution of integration logic needed for component integration.Integration Engine is Central runtime component of the Integration Server for receiving, processing, and forwarding messages.For more info please vist the below link:

4)..Why do not we create communication channel at sender side in http adapter?

We do not create Communication channels for sender side in HTTP adapter because they reside on abap stack and we specify the URL in the WebApplication which wants the communicate with XI.

The format of the URL is as below

http://<yourserver>:port>/sap/xi/adapter_plain?namespace=&interface=&service=&party=&agency=&scheme=...

Here u specify the details like namespace,service etc..,

Thanks,

Bhargav.

IDOC and RFC are come under the Abap stack

and remaining come under the J2EE adapters

i.e., SOAP,JDBC,RNIF,

Hi,

>>1.Where does HTTP runs ?

HTTP runs on ABAP Stack , it will communicate with the Integration server directly

>>2.What are the abap stack and java stack adapters?

On ABAP Stack------IDOC & HTTP

On JAVA Stack----File,JDBC,Mail,Soap,RFC, etc..

>>3.How Adapter Engine works and Integration Engine works? and their importance?
