Switching RFC destinations dynamically

[Amey-Mogare]

Hello All,

I need to implement a scenario in WD Java DC where depending on user’s country & lang, I need to call ARFC2 model with different RFC Destinations.

I cannot create multiple WD Java PCD objects and pass ‘sap-wd-arfc-useSys’ parameter with suitable value.

There should be only one WD Java PCD page, and when its opened by user, maybe in defaultPlug, I need to write this logic to get user’s country and select suitable destination.

Any ideas on how this can be achieved?

Thanks & Regards,

Hi,

It's possible, you can set the destination name in the constructor.

Please read note: 1920259 - ARFC2: Connecting to multiple backends.

Please check the below code. its may be useful : WDSystemLandscape API

boolean isconnExists = false;
         try { 
  String[] connectionNames = WDSystemLandscape .getJCOClientConnectionNames(WDSystemLandscape .getCurrentJ2EEClusterName());
  for (int i = 0; i < connectionNames.length; i++)
        {    
        String connectionName = connectionNames[i];  
              if (connectionName.equals(name))
  {   isconnExists = true; 
  break; 
  }
       }    
  }
  catch (WDSystemLandscapeException e1)
  {
  wdComponentAPI.getMessageManager().reportWarning("Erorr while retrieving the connection names");
  }
  if (!isconnExists)
      {
     try
     {  
         IWDJCOClientConnection connection = WDSystemLandscape .createJCOClientConnection("<<JCO ClientName>>" ,5, 10, 30, 10, "<<MessageServerName>>","<<SystemName>>", "<<LogonGroup>>", "<<Client>>", WDUserDefinitionType.getType("useDefinedUser"),"<<user>>","<<password>>", null, null, null, null, null, "en",null);
        connection.release();
      WDSystemLandscape.invalidateCache();    
     wdComponentAPI.getMessageManager().reportSuccess(("<<JCO ClientName>> + " created successfully");
                                     }
  catch (WDSystemLandscapeException e)
  {
  wdComponentAPI.getMessageManager().reportWarning(e.getMessage());
  }} else {wdComponentAPI.getMessageManager().reportWarning(<<JCO ClientName>>+ " already exists");}

Kindly let me know if you need any more information.
