Problems calling SOAP in JAVA program

Former Member — Fri, 24 Sep 2010 02:19:03 GMT

Hello Experts,

I'm quite new to using SOAP. I just want to ask how to call SOAP in JAVA specifically NetBean. I already created a webservice using the WSDL a created in SAP XI but problem is when I'm trying to invoke the webservice I always get error "401 Unathorized". Is there a way to specify the user name and password when calling the webservice via JAVA code?

Error Message:

Exception in thread "main" com.sun.xml.internal.ws.client.ClientTransportException: The server sent HTTP status code 401: Unauthorized

Sample Code:

public class Main {

/**

@param args the command line arguments

public static void main(String[] args) throws UnsupportedEncodingException {

ph.co.amkor.atp.ppmodule.synch.ReqCustomerNoDT Req = new ph.co.amkor.atp.ppmodule.synch.ReqCustomerNoDT();

Req.setCompanyCode(" ");

Req.setCustomerNumber("00110");

RespCustDetailsDT cdwsMI = cdwsMI(Req);

System.out.println("Customer :" + cdwsMI.getCustomerNumber());

System.out.println("Name :" + cdwsMI.getName());

System.out.println("Street :" + cdwsMI.getStreet());

System.out.println("Coutnry :" + cdwsMI.getCountry());

System.out.println("City :" + cdwsMI.getCity());

System.out.println("MSG Type :" + cdwsMI.getMessageType());

System.out.println("Message :" + cdwsMI.getReturnMessage());

}

private static RespCustDetailsDT cdwsMI(ph.co.amkor.atp.ppmodule.synch.ReqCustomerNoDT reqCustomerNoMT) {

ph.co.amkor.atp.ppmodule.synch.CDWSMIService service = new ph.co.amkor.atp.ppmodule.synch.CDWSMIService();

ph.co.amkor.atp.ppmodule.synch.CDWSMI port = service.getCDWSMIPort();

return port.cdwsMI(reqCustomerNoMT);

can you try this

BindingProvider prov = (BindingProvider) port;

        prov.getRequestContext().put(BindingProvider.USERNAME_PROPERTY, "username");
        prov.getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, "password");

Hello John Wu,

Points were given.

The code you gave me worked. Thanks! but now I'm having another error below. It seems that it did not returned anything at all cause cdwsMI object is null.

Error:

Hello John Wu,

It was successfully called when I've checked in communication channel monitoring and SXMB_MONI but I only see the request message but no response message. I believe this supposed to return a response since the setup is asynchronous. Alos noticed the the XML message it sent in SXMB_MONI message still has asynchronous stated and not synchronous.

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

- <!-- Response

-->

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

is asynchronous.

You will get a response only when the setup is SYNCHRONOUS and not Asynchronous.....is your above statement a typo?

What have you selected as Quality of service in the SOAP Channel....it should be Best Effort.

Sorry it was just a typo error. I setup synchronous Message Interface in Integration Builder: Design.

Re: Problems calling SOAP in JAVA program

Former Member — Fri, 24 Sep 2010 04:18:59 GMT

I setup synchronous Message Interface in Integration Builder: Design.

This is fine....but what about the quality of service option in Sender SOAP Channel? Have you set it as Best Effort.

You said that that the request is reaching SAP....now can you confirm for SAP developer that SAP is able to process this request and also to generate the response?

What are you using on the SAP side...PROXY/ RFC? I hope that it is configured to work in SYNC mode.

Abhishek.

Hello,

I am using RFC on SAP side specifically BAPI_CUSTOMER_GETDETAIL2. Setup is SOAP -> RFC. I already changed it just recently to Best Effort now I am having error in channel saying "error occured" after "request recieved" logs. Also below is the message returned by JAVA.

Error message in Java:

Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: Server Error

Are you sure that you have created all the required objects in SAP PI?

Did you confirm the working of request in SAP system?

Re: Problems calling SOAP in JAVA program

Former Member — Fri, 24 Sep 2010 05:46:36 GMT

Hi,

Yes, I just followed this steps. I created message mapping for the request and response part and assigned both in the Interface message both in response and request part.

Thanks,

Alfred

Former Member — Fri, 24 Sep 2010 05:48:18 GMT

It already worked when I use Exactly once option but problem is no response message received and no I've changed it to Best Effort it is now having error saying error occurred in channel monitoring.

provide details about each object that you have created in IR and ID of SAP XI/ PI for this interface.

This is a simple scenario...feel that you have missed some configuration somewhere.

Re: Problems calling SOAP in JAVA program

Former Member — Fri, 24 Sep 2010 06:09:16 GMT

Hi,

Below are the objects I've created.

Data Type:

ReqCustomerNo_DT

RespCustDetails_DT

Message Type:

ReqCustomerNo_MT -> using ReqCustomerNo_DT (Data Type)

RespCustDetails_MT -> using ReqCustomerNo_DT (RespCustDetails_DT)

Message Interface:

CDWS_MI -> synchronous/Outbound

Output Message : ReqCustomerNo_MT -> using ReqCustomerNo_DT (Data Type)

Input Message : RespCustDetails_MT -> using ReqCustomerNo_DT (RespCustDetails_DT)

Message Mapping:

Request_MM -> mapped ReqCustomerNo_MT with BAPI_CUSTOMER_GETDETAIL2(RFC)

Response_MM - mapped BAPI_CUSTOMER_GETDETAIL2.response (RFC) with RespCustDetails_MT

Interface Mapping:

CDWS_IM:

Source Interface -> CDWS_MI

Target Interface -> BAPI_CUSTOMER_GETDETAIL2

Messages:

Request: Mapping Program -> Request_MM

Source Message: ReqCustomerNo_MT

Target Message: BAPI_CUSTOMER_GETDETAIL2

Response: Mapping Program -> Response_MM

Source Message: BAPI_CUSTOMER_GETDETAIL2.Response

ZBSBACKEND

Why are you using the above Business System both as sender and receiver? The Business System ZBSBACKEND, would represent the SAP ECC system and you normally define a Business Service for the sender (in your case).

Hello,

I've just followed this steps on this site -> [http://www.riyaz.net/blog/xipi-consuming-xi-web-services-using-web-dynpro-part-i/technology/sap/6/]

I think I did all that it said right but still having error during testing

Hi,

So I need to define the soap channel on a different business system? I still don't know how to set another business system for JAVA. Can you show me how?

Thanks,

Alfred

Re: Problems calling SOAP in JAVA program

Former Member — Fri, 24 Sep 2010 07:10:57 GMT

Hello,

I think its just fine to use same Business system as stated in this forum. Someone said this below

"As mentioned above there is no need to create a Business System for entities outside your SLD boundaries.

You can create a Party in the ID, under that, create a Business Service for your SOAP Sender.

Under that Business Service you can define your SOAP Sender Communication Channel."

Re: Problems calling SOAP in JAVA program

Former Member — Fri, 24 Sep 2010 07:44:48 GMT

A Business System is required when you have to exchange message between SAP PI and SAP ECC system.

In your case JAVA application surely is not a SAP ECC system.....so you need to have a Business Service for it....assign the Source Message Interface (for SOAP) to this Business Service.
