Hi all 😉

I’m working with EntireX Mediator v 7.4.1.1.

I’m using the SOAP gateway to invoke a web service, and TCPMon in order to monitoring the requests/responses. When I create the SOAP gateway and I configure it with the wizard, TCPMon traces the mediator WSDL request and the WS response (there is communication at least…)

The WS accepts 3 string parameters (in0, in1 and in2) and returns another string (myactionReturn). At runtime, this exception occurs (traced in {MediatorHome}/host/logs/DefaultComponentFactory.xbd.log):

The line where the problem occurs is :

```auto

<step component="SagSoapGateway" xbd.soap.arg0.in0="parameter1" xbd.soap.arg1.in1="parameter2" xbd.soap.arg2.in2="parameter3" xbd.soap.handlefault="false" xbd.soap.operation="{{urn:myservice}}myaction" xbd.soap.port.qn="{{urn:myservice}}myservice" xbd.soap.res0.myactionReturn="" xbd.soap.service.qn="{{urn:myservice}}ServiceMyServices" xbd.soap.session="false" xbd.soap.style="rpc" xbd.soap.wsdl.url="http://localhost:9090/axis/services/myservice?wsdl" xbd.zid="N400049"/>
```

At execution time, TCPMon doesn’t trace anything (the failure is previous to the WS invocation).

Any idea?

Thanks in advance 😉

Hello Carlos,

The values to be specified in the xbd.soap.arg#… properties must be XPath expressions that return the values for the parameters for an RPC style service and appropriate document fragments for a document style service. The xbd.soap.res#… properites identify locations in the Mediator payload where the result(s) will be placed.

Hope this helps.
