Hi Experts,
I am using RFC to fetch some data from SAP and it is giving the following error.
<b>
Receiver channel 'Sys_ER3_UK_RFC' for party '', service 'ER3_UK'
Error can not instantiate RfcPool caused by:
com.sap.aii.af.rfc.RfcAdapterException: error initializing RfcClientPool:com.sap.aii.af.rfc.core.repository.RfcRepositoryException: can not connect to destination system due to: com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed

Hi Rao,
in addition with the sibani view you can check more and can do some setting to avoid these error in future.
just follow information about JCo pool it will help you alot.
, follow parge 10 of this link.
Also
refer to the SAP Library under SAP NetWeaver
>Application Platform (SAP Web Application Server) > Connectivity >Components
of SAP Communication Technology > Communication Between ABAP and Non-ABAP
Technologies > SAP Java Connector > SAP JCo Client Programming > Establishing
Connection to an SAP Server ® Connection Pools, or refer to the help of the SAP
NetWeawer Developer Studio for the description of the class JCO.Pool under SAP
NetWeaver Developer Studio Documentation ® SAP Web AS for Java Applications >
API WAS > Java Connector > com.sap.mw.jco > JCO.Pool.

Hi,
We get this error normally when R/3 system is down / cannot be reached.
Just try to login into R/3 system directly from abap stack.
Or if the issue is not solved,
Try the following steps..
1. Stop the RFC Communication channel in RWB
2. Start the same and check the status,
For this u can follow these steps:
Go to the RWB->Component monitoring->Adapter Engine-> choose communication channel monitoring and then choose your Communication channel.There you will find the buttons start and stop.
This technique works sometimes.
