Hi,
I am trying to set up a RFC Server which should connect to a SAP Message server with a logon group, which in turn should redirect it to the appropriate Application Server.
When connecting directly to the Application server everything works fine. When trying to use a message server while configuring the server details in the app.config file it gives a error with the attribute "GWHOST" not supported. To bypass this problem I tried hard coding the RfcConfigParameters as such:
public class SAPConfig : IDestinationConfiguration
{
public bool ChangeEventsSupported()
{
return false;
}
public event RfcDestinationManager.ConfigurationChangeHandler ConfigurationChanged;
public RfcConfigParameters GetParameters(string destinationName)
{
var parms = new RfcConfigParameters
{
{RfcConfigParameters.Name, "PRD"},
{RfcConfigParameters.MessageServerHost, "10.0.0.XX"},
{RfcConfigParameters.GatewayHost, "10.0.0.XX"},
{RfcConfigParameters.Client, "XXX"},
{RfcConfigParameters.LogonGroup, "GRPX"},
{RfcConfigParameters.User, "USERXXX"},
{RfcConfigParameters.Password, "PASSXXX"},
{RfcConfigParameters.SystemNumber, "0X"},
{RfcConfigParameters.Language, "EN"},
{RfcConfigParameters.PoolSize, "5"}
};
return parms;
} }
class CustomRFCServerListener
{
//LISTENER THAT WAITS FOR RFC FUNCTION CALL TO THIS APPLICATION FROM WITHIN SAP
private void WriteReply(object sender, string message)
{
Console.WriteLine(message);
}
[RfcServerFunction(Name = "Z_FUNCTION_TO_LISTEN_TO")]
public static void ZfunctionToListenTo(RfcServerContext myServerContext, IRfcFunction myFunction)
{
// DO A BUNCH OF STUFF
}
} }
//MANAGER CLASS THAT INITIATES RFC SERVER
class CustomRFCServerManager
{
private RfcServer _sapHost = null;
public void InitializeServer()
{
var rfcHandlers = new Type[1] {typeof (CustomRFCServerManager)};
var myConfig = new SAPConfig(); //Class created in code snippit above
_sapHost = RfcServerManager.GetServer(myConfig.GetParameters("PRD"), rfcHandlers);
_sapHost.Start();
}
}
As stated above everything works perfectly when connecting directly to the sap Application server. However when using this method where I try to retrieve the config data from the SAPConfig class, I get the following error: "Hard-Coded logon parameters not allowed when using a ServerConfiguration". Which is understandable, but how else can one set up a connection to a SAP Message server (MSHOST in older connector / MSSERV in the new connector)? Does anybody have an example of how the app.config should look for this scenario or is there a common solution for the attribute support issue?
Any help would be greatly appreciated!
Kind regards,
