I am working on a POC currently where I need to call a BAPI inside S/4HANA On-Premise from a cloud application using Java. For this I am using SAP Cloud SDK.
For initial setup I followed these steps from the guide "Set Up Your Local Infrastructure to Develop with SAP Cloud SDK".
I am trying to call BAPI_COSTCENTER_GETLIST1 from my application. Here is the code snippet:
final BapiRequestResult resultGetCostCenters = new BapiRequest("BAPI_COSTCENTER_GETLIST1")
.withExporting("CONTROLLINGAREA", "BAPI0012_GEN-CO_AREA", "0001")
.withTable("COSTCENTERLIST", "BAPI0012_CCLIST").end()
.withTableAsReturn("BAPIRET2")
.execute(destination);
And here the declaration of destination variable:
Map<String, String> destinationProps = new HashMap<String, String>();
destinationProps.put("Name", "SampleDestination");
destinationProps.put("URL", "abcdefg.wdf.sap.corp");
destinationProps.put("Type", "HTTP");
destinationProps.put("Password", "<system_password>");
destinationProps.put("Authentication", "BasicAuthentication");
destinationProps.put("User", "<system_user>");
final Destination destination= new DefaultDestination(destinationProps);
But from execute(), one exception is being thrown which says:
org.apache.http.ProtocolException: Target host is not specified
Here is the complete stack trace:

I have tried providing http or https at the starting of the URL. But still nothing seems to work. Though I am new in this but I assume calling BAPI is different than calling any HTTP API. In that case how to approach ?
Thanks in advance.
