ResourceMultiParentClassLoader-3d19dc64-alive - ERROR in SOAP Recvr Channel

Hi,
We have a WS Sender to SOAP Receiver scenario :- The message from the IE has been processed but has failed in the adapter and throws the below error :-
Audit Log of Receiver SOAP Communication Channel :-

need some suggestions as to what went wrong?!!

Hello
Check the note #1452307 Sync-XI resp-message fails with ClassCastException in PI 711. Are you on a lower patch release?
Are you using any modules in the adapters? Use the tool in note #1514898 Diagtool for troubleshooting XI, to get better trace information.

Error in Soap Communication Channel

Hi All,
I am using Soap as sender from UPXI and again Soap as receiver in EUPI but while doing end to end test SOAP sender channel was failing.
Below was the error which I cam seeing the channel mointoring.
Message processing failed. Cause: com.sap.engine.interfaces.messaging.api.exception.MessagingException: SOAP: response message contains an error XIAdapter/HTTP/ADAPTER.HTTP_EXCEPTION - HTTP 500 Internal Server Error
Can you please help me in resolving this issue.
Thanks,
Mahi.

Hi Mahi,
I understand from above post that you are using SOAP to SOAP interface, however can you also elaborate on following:
1) How are you testing the interface?
2) Where do you see this error?
3) Are you using ICo or classical configuration scenario?
HTTP 500 is a generic error and could have been caused because of any reason. If you are using a tool like SOAPUI etc, you can try looking into the text of error to see what error reason is displayed. Also worthwhile looking in to the runtime workbench or sxmb_moni (if dual stack processing) to see what is the status of message processing.

Error in SOAP Receiver channel

Hi,
We are working on IDOC to SOAP Scenario (Connecting to third party).
We have configured the SOAP Receiver channel with the Target URL and teh corresponding SOAP Action.
But the SOAP Receiver channel gives the error while processing and sends back the following error message in log :
"Delivery of the message to the application using connection SOAP_http://sap.com/xi/XI/System failed, due to: com.sap.aii.af.ra.ms.api.RecoverableException: SOAP: response message contains an error XIAdapter/PARSING/ADAPTER.SOAP_EXCEPTION - soap fault: Server was unable to process request. ---> Value cannot be null. Parameter name: s."
Payload seems to look fine in XI and SAP.
Any help on this ?
Thanks and regards,
Vikas

Hi Vikas,
Copy the payload from SXMB_MONI after mapping and check with SOAPGUI or Altova, if it working fine then your payload is good. You can use the WSDL to ganarate and send independent soap request from these tools.
Besides this IDOC is Asyc, you need to use RequestResponseBean and ResponseOneWayBean to get the response from SOAP. Check the following and try to simulate it.
https://wiki.sdn.sap.com/wiki/display/XI/File-RFC-File%28Without+BPM%29
Server was unable to process request. ---> Value cannot be null. Parameter name: s."
The error specifies that the request has null value, check the parameter specified in the error message and make sure that is not null while you are sending the request.

"Unauthorized" error for SOAP receiver channel

Hi all,
I have a scenario in which I am calling a .NET web service from a UDF in which the XML payload is constructed manually. I have configured a SOAP receiver channel. Also, since the web service needs certificate authentication, I have checked the corresponding parameter in the SOAP channel and selected appropriate client certificate.
When I execute the mapping, I get the following error -
com.sap.aii.mapping.lookup.LookupException: Exception during processing the payload.Problem when calling an adapter by using communication channel SOAP_RCV_IMWS_Change (Party: , Service: IMWS, Object ID: dda07d364ca73d4ab9e89e562a971b36) XI AF API call failed. Module exception: 'com.sap.aii.af.ra.ms.api.RecoverableException: invalid content type for SOAP: TEXT/HTML; HTTP 401 Unauthorized: java.io.IOException: invalid content type for SOAP: TEXT/HTML; HTTP 401 Unauthorized'. Cause Exception: 'invalid content type for SOAP: TEXT/HTML; HTTP 401 Unauthorized'.
Is this related to error in certificate authentication process, OR wrongly formed XML payload OR anything else ?
Regards,
Shankar

No. I didn't provide any login info. The web service doesn't specify username login requirement. Instead, it needs client certificate for authentication, which I provided in SOAP receiver channel.
I am testing the web service by executing the message mapping. The web service was executed successfully from its 'Test Page' like for SAP web services we have web service navigator. So it runs ok from that test page, but gives error when called from UDF.

Shankar

Error in SOAP receiver channel in Synchronous Proxy to SOAP scenario

Hi all,
We are experiencing an issue with a synchronous Proxy to SOAP scenario. Getting below error message in the SOAP receiver communication channel for the response message.
SOAP: Response message contains an errorXIAdapter/HTTP/ADAPTER.HTTP_EXCEPTION - HTTP 500 Internal Server Error
Returning to application. Exception: com.sap.engine.interfaces.messaging.api.exception.MessagingException: Error encountered while executing mapping: com.sap.aii.af.service.mapping.MappingException: com.sap.aii.utilxi.misc.api.ResourceException: Could not determine mapping steps for message 1364b76e-ecbf-11e4-85f4-000023acfde6.
We are running PI 7.4.
Any help is appreciated.
Thanks,
Pushpa

Hi,
Seems the Receiver Webservice is not reachable. Did you try to test it using SOAP UI tool.
1. Test a fresh message from local SOAP UI tool.
2. Pick 3rd party WSDL file and Import in SOAP UI tool.
3. Put some dummy data for mandatory fields
4. Trigger it msg and ckh if you get successful / response msg.
5. Check if firewall is open and that URL is not blocked.
Hope it helps

Error with Soap sender channel

I have a scenario SOAP->Proxy ..whenever I send a message through SOAP its giving error as below:
com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.engine.interfaces.messaging.api.exception.MessagingException: Connection SOAP_http://sap.com/xi/XI/System is currently not started.
Please help me in rectifying this...

Kiran,
strange thing is that when we remove the standard module from the channel then its workign fine..
Well, you can try couple of things more -
1. Re-start the java engine.
2. If step 1 doesn't work, delete the channel -> activate the change list -> create a new channel and try again.
I feel that after step 1, it should work. Let us know how it goes.

Error at SOAP response channel

I have created a synchronous PROXY to SOAP scenario. But I am getting the following error in the receiver SOAP Adapter.
Message processing failed. Cause:

Hi,
We have faced similar problem in production some time back .
At target system end web service validates the payload below inserting into back end system (d/b).If the validation fails then it throws the error to PI system .
For us the backend system notified that there end front end service validation failed due to data issue and thrown exception to PI.
Share the payload to target system folks and ask them to check ,they will have test suite to test it from there end . If not share the time at which you received error,they will check there logs and update you on the cause .

Getting error in target SOAP communication channel

Hi all,
I am trying to send data from Http client to Webservice.In moni i got a message processed successfully means getting black flag.But i got an error in SOAP Communication channel as "error in response".
I got this message from that error
<b>"SOAP: response message contains an error XIAdapter/HTTP/ADAPTER.HTTP_EXCEPTION - HTTP 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied. )"</b>
Source side i dont configure Http adapter.Target side i configured SOAP adapter.In that SOAP adapter i configured these fields.1)Target URL 2)Configure Proxy 3)Configure proxy user authentication.
I want get response from webservice.Please help me.
Thanks,
Gopi.

Hi,
Make sure that you have specified the proper host and port values, in the text box that appears when you check the configure proxy check box(in receiver soap adapter).
Looks like the webservice requires a proxy authentication.
Select the check box "configure proxy user authentication"(in receiver soap adapter) and provide the correct username and password.

Error in SOAP Sender Communication Channel

Hello Gurus,
I am trying for a SOAP (Axis) -> PI -> IDOC scenario and getting an error while sending message to SOAP Channel.
Message structure used
<?xml version="1.0" encoding="UTF-8"?>
<MaterialData>
<field1>value</field1>
more fields
</MaterialData>
Basically a XML message.
I am getting below error message for Axis (channel monitoring):
MP: exception caught with cause org.xml.sax.SAXException: Bad envelope tag: MaterialData
Can you please let me know what should be the message format when testing Axis? I do not intend to use any SOAP envelope.
I have already referred: Re: SAP PI 7.0 Receiver SOAP Axis (Bad envelope tag: html)
Please help.
Thank you!

Hello,
Can you please let me know what should be the message format when testing Axis? I do not intend to use any SOAP envelope.
Correct me if I'm wrong, but I think you will only be able to plain message to the Axis sender when using REST. See SAP Note 1039369 FAQ XI Axis Adapter, under Sender Adapter General Question 35.
35. Can I post a plain no-soap request (REST) to the sender adapter servlet?
Yes. You need to include a query parameter rest in the request URL, as http://host:port/XIAxisAdapter/MessageServlet?...&rest. For the availability of this feature, refer to Note 1448849.
All the other messages require a SOAP Envelope.
Hope this helps,
Mark

HTTP Error 501 with SOAP Sender channel

Hello,
i've am simple Question:
I want to call the following SAP XI SOAP Sender channel "MySoapSenderChannel":
XI-Parameters:
namespace: <myInterfaceNamespace>
Interface: <myAsynchInterface>
QoS: Exactly Once in Order
Queue: MY_QUEUE
We do not care about the Response - so the processing is asynchron.
Thus my interface mapping maps to asynch interfaces. The desitnation
is an ABAP Proxy. The configuration has been done and tested.
Here my question:
according the documentation, the URL has the following syntax:
http://host:port/XISOAPAdapter/MessageServlet?channel=party:service:channel.
In our case:
http://<myHost>:8002/XISOAPAdapter/MessageServlet?channel=:MyService:MySoapSenderChannel.
But when i generate a WSDL for the interface out of the Configuration, the address is:
<soap:address location="http://<myHost>:8002/sap/xi/engine?type=entry&version=3.0&Sender.Service=MyService&Interface=...
and so forth.
But was is the difference between these 2 possibilities?
Why do i get HTTP Error 501 when i use the URL from the documentation (the first one)?
Thanx in advance
Gunnar

Gunnar,
I will suggest you to go through it once to check all your connection.

Kindly advice !!!
Regards ,

1. Check PI id and password is working fine.
Check if the user you are using has SAP_XI_APPL_SERV_USER role.
Another way is to pass id and pwd in URL
Try to pass the User ID and Password in the URL( the URL which is given to the webservice).
Example: http://host:port/XISOAPAdapter/MessageServlet?channel=party:service:channel &sap-user=xxxx&sap-password=xxxx
2.Provide SOAP URL like -
http://host:port/XISOAPAdapter/MessageServlet?channel=party:service:channel

SOAP Receiver Channel error

Dear PI and SOAP experts:
I have been having trouble getting a SOAP Receiver channel working for a webservice. I get the following error in the SOAP receiver channel:
SOAP: response message contains an error XIAdapter/PARSING/ADAPTER.SOAP_EXCEPTION - soap fault: content-type of the request should be text/xml
I also forced the content-type as text/xml;charset=utf-8 from PI by using the MessageTransformBean as a module in the SOAP Receiver channel, but still getting the same response.
When I called the same w/s using XMLSpy and SOAPUI, it works fine and I get a positive response. So there is no problem with the webservice.
I also tried calling a different webservice from PI and that works fine too. So there is no problem with outbound communication with PI and the SOAP receiver channel either.
But whenever I send the request from PI to the first webservice it gives me the above error.
Thank you.
Param.

Hi Param,

Hi,
First of all check the URL in your receiver SOAP adapter. The error comes from the web service server. It says that the request message is wrong.
1.fill field SOAPAction in the receiver soap adapter
2.fPlease find the related information here
http://help.sap.com/saphelp_nw2004s/helpdata/en/29/5bd93f130f9215e10000000a155106/content.htm
