Calling Portal Services via RFC 
Procedure
...
1. Portal services that have to be called via RFC must implement the interface com.sapportals.portal.prt.service.rfc.IPRTRFCListener:
public class TestRFCEngineService implements Iservice, IPRTRFCListener |
2. The portal service should then register in its afterInit() method the RFC it requires using the following function of the RFC Engine Service:
setFunctionCallListener( String nameOfFunction, String nameOfService) IRFCEngineService service = (IRFCEngineService) mm_serviceContext.getService(IRFCEngineService.KEY);
service.setFunctionCallListener( "MY_R3_FUNCTION", "My Service or application name"); |
3. The portal application has to reference the RFC Engine Service:
<application alias="TestRFC"> <application-config> <property name="ServicesReference" value="RFCEngine"/> <property name="releasable" value="true"/> </application-config> |
4. Finally, the portal service must implement the function handleRequest to receive calls from an SAP R/3 System:
public JCO.Function handleRequest(JCO.Function function, IUserContext userCtx) throws Throwable { try { JCO.ParameterList input = function.getImportParameterList(); JCO.ParameterList output = function.getExportParameterList(); JCO.ParameterList tables = function.getTableParameterList();
if (function.getName().equals("STFC_CONNECTION")) { output.setValue(input.getString("REQUTEXT"), "ECHOTEXT"); output.setValue( "This is a response from the TestRFCService side!", " RESPTEXT "); } return function; } |
