Consuming ABAP webservice in Java

Hi Gurus,
We are publishing webservices from SAP and Java team is consuming them. For accessing the webservice from java , we are maintaining User name and Password in SICF for that service.
Now if we donot maintain the User name and Password in SICF for that service then Exception "Unauthorised " is coming in Java.
We want to pass the User name and Password from Java. How to achieve this.
Thanks
Jitendra

Hi John,
thnx for quick response. i have given WSDL to Java team but they are unable to find " Logon service in the WSDL".
Can u tell us for which XML tags we should search.
Thanks

Consuming MII WebService in Java WebDynpro

Hello,
We are facing a strange situation...
We define a transaction in MII to be consumed as WebService in Java WebDynpro. This transaction is a simple query on a DB returning 4 fields :
Shift code : SHIFT
Shift description : DESCRIPTION
Start time : START_TIME
End time : END_TIME
It works fine, we use the import adaptative web service wizzard in netweaver developper studio to use this WS...
But if we to an update on the webservice, changing a field name for example (SHIFT -> SHIFTCODE), we start to have trouble...
We got then the very helpful error message :
Exception on execution of web service with WSDL URL '<sever>/WebServices/GetShift' with operation 'Xacute' in interface 'XacuteWSSoap'
If I display the model info using wdContext.currentRequest_XacuteElement().modelObject().associatedModelClassInfo().getModelInfo().toString()
I got the following (extract) :
<ModelClassPropertyInfo name="SHIFT" dataType="com.sap.tc.webdynpro.model.webservice.types.string(java.lang.String)" readOnly="false" qName="SHIFT" required="true" backendType="null"/>
As you can see, the model definition is NOT updated and we still have SHIFT as name instead of SHIFTCODE...
If someboby has an idea, it will save us our life ;o)
Thank you
PS:it the same behaviour if we add a field...

Oliver -
Did you try to reimport the WS model ..? If yes and still doesn't work...Try to delete the old proxy in webdynpro ( adoptive ws) and import again.
To avoid code changes,you can give same old name while fresh import.
Adoptive WS in webdynpro is not really like Adoptive RFC .It has some limitations.
Thanks

Consuming ABAP Webservice in Webdynpro app

Hi,
I have wrote a webdynpro app for consuming ABAP webservice. I used the procedure in the link below
http://wiki.sdn.sap.com/wiki/display/WDJava/ConsumingABAPWebServiceinJavaWD
Everything seemed to be went well, I created model and Webservice destinations. I have written the code for calling the webservice, which does not return data as part of response. I mean though the RFC returns data at the backend,its not showing the returned records in the webdynpro table.
I have also tried checking the same by setting external break point. when the webservice is executed from my webdynpro app,it goes to the ABAP debugger and i could clearly see the records in the export parameters of RFC,but the same is not returned in the reponse object.
Could any one let me know what could be missing. Any help is greatly appreciated?
I have used the following code in Init method of my View
Request_ZMYRFC input=new Request_ZMYRFC (model);
wdContext.nodeRequest_ZMYRFC ().bind(input);
ZMYRFC req= new ZMYRFC (model);
req.setPUserid("EDLAS00C");
req.setPLtc("E");
input.setMYRFC (req);
IWDMessageManager manager = wdComponentAPI.getMessageManager();
    try
    wdContext.currentRequest_ZMYRFCElement().modelObject().execute();
      wdContext.nodeResponse().invalidate();
      wdContext.nodeZMYRFCResponse().invalidate();
      wdContext.nodeReturn_res().invalidate();
     wdContext.nodeItem_res_ret().invalidate();
      wdContext.nodeILtcg_res().invalidate();
      wdContext.nodeItem_res_ltcg().invalidate();
    catch(Exception e)
      manager.reportException(e.getMessage(), false);
Thanks

santosh,
Check provider system defination in nwa for webservice.After this mapp the provider system and service group after wd app deployed.This is mandatory while consuming webservice in webdynpro for latest versions of CE7.11 or later.for reference check this article/document. http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/50d70a19-45a3-2b10-bba0-807d819daf46

Hi,
Thanks for your response. I did the same as mentioned in the link provided by you. But it is not working . I am still getting "Access denied" javascript error in the second line ( xmlhttprequest.open) . Below is my code.
var auth = make_base_auth('userid','password');
xmlhttprequest.open("POST", URL, true);
xmlhttprequest.setRequestHeader('Authorization', auth);
xmlhttprequest.setRequestHeader ("Content-Type", "text/xml");
xmlhttprequest.onreadystatechange = getDataList;
xmlhttprequest.send(SOAPEnvelope);
Please let me know your thoughts. Thanks again for your response.

Consuming ABAP Webservice from Android device

Dear Experts,
I am ABAP developer (limited knowledge on android) trying to connect Android device to a.SAP Webservice
Through trial and error and help from SDN and Android forums i managed to link up the ABAP webservice and android using KSOAP2 API.Its working perfectly now but only when i save the username password for SAP access in the webservice settings in transaction SICF.I need to access the service by passing the username and password values through the SOAP request header but so far my efforts have failed me.im presently using the following code to pass my auth values.
I would be grateful if you can point me in the proper direction.
       String NAMESPACE = "mynamespace (works properly without auth)";
        String METHOD_NAME = "mymethod (works properly without auth)";
        String SOAP_ACTION = "mynamespace/mymethod (works properly without auth)";
        String URL = "myURL{works properly without auth)";
        SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
        Request.addProperty("Purchaseorder","4500001168");
        Request.addProperty("Username", "myusername");
        Request.addProperty("Password", "mypassword");
       SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
       envelope.setOutputSoapObject(Request);
       HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try
           androidHttpTransport.call(SOAP_ACTION, envelope);
           SoapObject response = (SoapObject)envelope.bodyIn;
           String testValue = response.getProperty("PoHeader").toString();
           AlertDialog alertDialog = new AlertDialog.Builder(this).create();
           alertDialog.setMessage(testValue);
           alertDialog.show();
       catch(Exception e)
            e.printStackTrace();
Thanx & Best Regards

Hi,
you can develop a custom Transport class wich extends the: HttpTransportSE class by authentication features.
example:
public class AuthTransportSE extends HttpTransportSE{
     private String username;
     private String password;
     public AuthTransportSE(String url, String username, String password) {
          super(url);
          this.username = username;
          this.password = password;
     protected ServiceConnection getServiceConnection() throws IOException {
          ServiceConnection midpConnection = new ServiceConnectionSE(url);
          addBasicAuthentication(midpConnection);
          return midpConnection;
     protected void addBasicAuthentication(ServiceConnection midpConnection) throws IOException {
        if (username != null && password != null) {
            StringBuffer buf = new StringBuffer(username);
            buf.append(':').append(password);
            byte[] raw = buf.toString().getBytes();
            buf.setLength(0);
            buf.append("Basic ");
            org.kobjects.base64.Base64.encode(raw, 0, raw.length, buf);
            midpConnection.setRequestProperty("Authorization", buf.toString());
Afterwards you can initialize the Webservice with:
AuthTransportSE androidHttpTransport = new AuthTransportSE(URL, userName, pasword);
Cheers,
Dennis.

hi All,
i tried the all ways provided in sdn to create a webservice in ABAP when i test its working fine on j2ee server.
when i call the same webservice from webdynpro its throughing this error can any body kindly help me in this.
java.rmi.RemoteException: Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (502) Proxy Error ( The ISA Server denied the specified Uniform Resource Locator (URL). ). The requested URL "xxxxxxxxxx".
Thank you.
venkat.

Hi Venkatramana,
The class of the ProxyGenerator is com.inqmy.lib.wsdl.ProxyGenerator. It is located in <SAPj2eeEngine_install_dir>/cluster/server/additional-lib/inqmysoap.jar or <SAPj2eeEngine_install_dir>/alone/additional-lib/inqmysoap.jar file. In addition the following JAR files must be included in your classpath - mail.jar, activation.jar, inqmyxml.jar, inqmysoap.jar, located in <SAPj2eeEngine_install_dir>/cluster/server/additional-lib/ or <SAPj2eeEngine_install_dir>/alone/additional-lib/ directory. You need also the inqmy-lib.jar file in <SAPj2eeEngine_install_dir>/cluster/server/lib/ or <SAPj2eeEngine_install_dir>/alone/lib/ directory in order to run the generator.

Consuming ABAP WS

Hello gurus,
please help me. I've faced problem with consuming ABAP webservice. Here's the original wsdl:
[WSDL definition|https://docs.google.com/document/d/1QiuguhN4ZniOUFkWWq2J-uH6Jqjc5wYCvmloAgqDDWs/edit?hl=en]
here's the response from WS:
[WS Response|https://docs.google.com/document/d/14fIkoBBw92m8fNS-hdLsY2xYoieBBCtvhf7YGt_y4Vc/edit?hl=en]
Question: how to enforce SAP to set prefix for all elements without prefix in the response xml? For instance i wanna have :
<n0:IdIncomeRecord>1 </n0:IdIncomeRecord>
intead of
<IdIncomeRecord>1 </IdIncomeRecord>
Thanks in advance.

To my knowledge, there seems to be little support to manipulate the generation of WSDL. But, explore the SOAManager transaction for any help related to it.

JAVA webservice to ABAP Webservice

Hi,
There is a Webservice developed in Java and published.
The same webservice we are now develping in ABAP. Though there is no change in the functionality of the webserice, the WSDL generated for ABAP webservice is looking different than the one for JAVA. How to resolve this issue? I do not want to ask the service consumer to regenerate the Clinet Proxy for the new WSDL.
Could you please help me in resolving this issue?
Thanks & Regards,
Kishore Babu T

Hello Johannes,
Which WSDL do I need ? In the wsnavigator I can choose RPC or Document, and then Default or SAP_WSDL to download the WSDLs.
Try this: [Accessing a Service|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/b8/a3cca166d440c29931c0c5494c32e5/frameset.htm]
And do I need to publish the webservice (which I want to consume) on the Java stack ? or ist it already published when the wsnavigator can access it ? (the service resides on the Java stack, and I want to consume it from the ABAP stack from the same system)
In short, no. You can safely use the Web service without publishing it - as Olivier explained, you need only the WSDL.
The "publishing" term is usually used when you register (publish) a Web service in the UDDI server or the Services Registry. Publishing is only relevant if you want other people to be able to locate the registered service in the UDDI server.
Hope this helps,
Rossen

Consuming a webservice in ABAP ECC 6.0 without using XI/ PI

Hi Experts,
I wanted to consume an external webservice without using XI / PI.After doing my homework and search on sdn I came to know that we can consume webservices in ABAP using proxies using SE80(Enterprise Services).
I am trying to create a client proxy with the URL of webservice.It asks me the option to choose between URL or HTTP.
I am selecting URL and in the second screen it asks about the package details and after that it finishes.Later I get an error message stating "NO VENDOR SPECIFIED".Its not allowing me to create a proxy.
So, here are my questions.
Does anyone faced the same kind of problem?
Can we really consume a webservice without using XI / PI or any other middleware?
Is it possible to consume the webservice only with URL or WSDL file ?
Please let me know the exact process.
Thanks in Advance.
Shanker Pandey.

How to consume a ABAP webservice in a webdynpro app?

Hi,
I have a BAPI in ABAP that is exposed as a webservice. I want to use this to build a webdynpro app so that i can consume this webservice. This BAPI returns the Employee data. As soon as the person logs into the portal i am going to pass his login id to this BAPI so that it retrieves the Employee data for that user id. But i need to know the procedure of consuming this webservice in a webdynpro app. Any pointers in this regard will be greatly appreciated.
Thanks,
Arun E V

Hi Arun,
Consumption of a web service is univesal I guess so it wont matter if it is an ABAP webservice. For consumtion of webservice in Web Dynpro you can go through the following tutorials

Consuming PI Webservice from Webdynpro Java Not working

Hello SAP,
Environment: CE 7.2.
Resolution expected immediately, Helpful answer is highly appreciated.
Is the namespace should not exceed 60char for PI Webservice, for executing the webservice from Webdynpro Java.
I tried with all the options in executing the PI Service from Webdynpro Java, None of the options worked. I am facing the below error while I was calling the PI Webservice.
I don't see any problem from Webdynpro Java, what ever the procedure I have followed is the standard procedure.
Fortunately when I execute the service from Webservice Navigator, it is working as expected. The same webservice when I consume it from Webdynpro Java it is not working
Options tried so far:
1) Published the Services to Service Registry and there by consuming the PI Service from Service Registry - Not worked
2) Tweaked the URL with few options - Not worked (Tweaking the URL, ex: portType, Binding)
3) Changing the Business Systems in PI and there after calling the service - Not worked
4) Initializing the code, instead of creating Service Controller and calling the PI Service - Not worked.
5) Created a Provider System and tried to call the PI Webservice from Provider System - Not Worked
For all the Options, I am facing the same error which is provided in the screenshot.
Below procedure which I have followed for calling the PI Webservice:
1) Created Adaptive Webservice Model
2) Provided PI Webservice URL (It prompts for PI System UserId and Password)
3) Selected Option - No Service Group Configuration
4) Provided Logical Destination
6) Completed creation of Model
7) Added the model as a UsedModel
8) Right Click on Comp Contr. and selected Apply Template and Created a ServiceController for the model (Entire mapping to comp contr, Initializing the nodes is taken care by Service Contr.)
9) Created an Template Action button and there by calling execute method which is auto rendered from CompContr..
10) Build the project.
11) Activated the code and Run the Application.
12) Getting the below error which is showed in the message.
ERROR MESSAGE:
Exception on execution of web service on destination 'GetPIHRPeopleData' for operation 'SI_CreateHRPeopleData_OS' in interface 'SI_CreatePeopleCompany_OS'

Hi Sankar,
If the webservice is working fine in the Wsnavigator then there is some problem with importing the webservice in webdynpro for Java. Please check the required parameter for creating the Adaptive Webservice Model. After adding in the used model and compoent controller binding, you need to write code for to execute the webservice model.
Please check the code for initialization and execution for the webservice and then test it.
Best Regards,
Arun Jaiswal

Error While Consuming the webservice in ABAP

Hi,
I am trying to consume a webservice in ECC. I have imported the WSDL and generated the proxy. Did the configuration in the SOAMANAGER. While calling the webservice from the program I am getting the following error message. "SRT: Unsupported xstream found: ("HTTP Code 400 : Bad Request")"
Any help is appreciated.
Thanks
Raghavendra Kuamr

Hi,
Check ST11 to find detailed log of issue, most likely you are passing "WS-A" message id along with request (check settings in SOAMANAGER Logical Port).
Try calling service after suppressing "Message Id transfer". See SAP Note: 1361688 and related notes in 0001292171
