RFC -> XI -> Web service

[Former Member]

Hi All,

I have a RFC -> XI -> Web service synchronous scenario.

After setting up scenario in XI, I execute RFC. When I check sxmb_moni, it shows me error.

The error is pasted here.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

- <!-- Call Adapter

-->

- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

<SAP:Category>XIAdapterFramework</SAP:Category>

<SAP:Code area="MESSAGE">GENERAL</SAP:Code>

<SAP:P1 />

<SAP:P2 />

<SAP:P3 />

<SAP:P4 />

<SAP:AdditionalText>com.sap.aii.af.ra.ms.api.DeliveryException: failed to get the input stream from socket: java.lang.NullPointerException</SAP:AdditionalText>

<SAP:ApplicationFaultMessage namespace="" />

<SAP:Stack />

<SAP:Retry>M</SAP:Retry>

</SAP:Error>

Can somebody explain me, why is this or to cross-verify my settings, steps in detail to set up this type of scenario.

Please don't take me to the documentation present here which explains about configuring Web service based scenario.

I have already looked at it and understood that it's not much useful at this stage.

Your help is highly appreciated.

Thanks & Regards,

Hi Smita,

How are you doing the communication from FRC ==> XI ??

1. Are you using Outbound(sender)RFC Adapter, if so did you create a registered program for communication from r3 to XI (rfc destination

sm59->tcpip)

2. Are you using an outbound(Sender) Client abap proxy??

3. Are you calling an external webservice(not in XI)if

so make sure the soap action is correct

Hi Naveen,

Creating proxy is really necessary to call any web service?

If so, then I am failing at that point.

I have not designed specific outbound message interface for RFC. While designing message mappings or mapping interface I use RFC as one of the source interfaces.

Yes, I have created RFC Destination of TCP/IP type to configure RFC communication channel.

Please correct me for proxy object.

Thanks & Regards,

Hi Smita,

You are correct on the outbound interface, you dont have to create a new interface, you could jsut use the rfc.

You dont have to create a proxy for webservice. Find out the soap action of the webservice you are trying to use. Define a message type in Xi with the same structure as in webservice soap action. Define an interface with this message and mapp it to ur rfc interface.

In Directory/Configuratiion, create a reciever soap adapter, specify target url (webservice url) and default saop action (its the method ur are trying to call in webservice)

Hi Navin,

Thanks for all ur inputs.

I have created SOAP receiver in Integration Directory and created default soap action for it.

I guess, I don't have to create any data type or message type as in external definitions I have already imported WSDL of my web service and it gives me all required interfaces.

So, I map RFC interfaces directly against interfaces of web service without creating any data type or message type.

Is it ok?

Thanks & Regards,
