IDocServerExample and using load balancer in place of Gateway

[chiragsanghavi]

Is it possible to write IDOC Server program in Java and leverage Load Balancer/Message Server on SAP in place of Gateway ?

We want to avoid using Gateway as it acts as a single point of failure.

Hi Chriag,
currently, there is no way to receive an IDoc from an ABAP system via RFC without using the gateway. It could be that you refer to an IDoc being sent via an HTTP channel as IDocXML, but this is then not receiving via IDocLibrary.

Best regards,
Markus

Hi Chirag,

You can configure a high availability gateway scenario, see SAP Note 1010990 - Configuring a Standalone Gateway in an HA ASCS instance.

Best regards,

Thanks antal.perger will pass this to SAP Basis team.

Here is my scenario - It seems that most 3rd Party middleware require following values to build an IDOC Listener (In order to leverage JCoIDocServer from JCO/IDOC Library).

jco.server.gwhost
jco.server.gwserv

It seems that some of the tools such as IIB are able to bypass that (not require gwhost and gwserv) and still retrieve IDOCs from SAP. Is that supported thru a newer SAP JCO version with new classes? Is there a different API that allows such communication?
