How to consume webservices hosted on NW CE 7.31 in Gateway to expose data out as oDATA

Hi Experts,
I have NW CE 7.31 on Java Stack. I have SAP-MDM webservices hosted on the same.
How can I access those webservices in NW Gateway to expose data retrieved as oDATA (e.g for Mobile Apps in UI5) ?
Thanking in advance.

How to consume webservices i.e WSDL file in Webdynpro ABAP.

Hi experts,
I have WSDL file in my local system, configured using SOAMANAGER ,a proxy class is generated,when i test it prompts for username and password after entering the required data it is executing fine.
I called the the PROXY NAME in my WD component using service call , a method is generated . But when i pass the values in importing parameter getting an error "Null reference object".
I think this error is for Authorization ??
Please help me..
Thanks
Aisurya

Hi,
instead of service call, try calling the proxy class method by explicitly creating object and then passing parameters etc.
Define context, attributes and then pass those to proxy method.
Thanks,

How to Consume a WebService in JSP DynPage

Hi Friends,
We have created a Web Service and We want to Consume that in my JSP Dyn Page.
Please let me know how to consume the Web Services that are created.
I am having a WSDL File and need to consume it in Enterprise Portal Applications.
Thanks in Advance.
Regards,
Palani

Hi Palani,
Create a Portal Application and access the External Web Service (Say for example, http://api.google.com/GoogleSearch.wsdl ). Create the Portal Application Object -> Portal Web Service -> Portal WebService from wsdl file -> Client Side -> Enter the Wsdl file as http://api.google.com/GoogleSearch.wsdl -> Select the methods to expose -> Enter the service name, Alias and package name should be a unique one. and finish.
Create bean to set the values.
In your JSPDynpage Component enter the following code:
public void doInitialization(){
YourServiceName obj=(YourServiceName) PortalRuntime.getRuntimeResources().getService(YourServiceName.KEY);
MyBean beanObj = new MyBean();
beanObj.setterMethod(obj.calltheMethodinWSDL());
And in your JSP page, call the bean getter method.
It's overview only, you can do it.

How to consume json webservice in abap?

hello every one please help me how to consume json format webservice in abap.
i am new in abap please help me out .
Thanks&Regards

hi check this,
First create a web service in SAP. The blog by Uwe Kunath descibes this clearly. Then create an Xcode project and use the ASIHTTPRequest wrapper to connect to the web service. Parse the response with the KissXML parser. A more out of the box solution is NetWeaver Gateway. It also let you use SAP web services but it also generates iOs code for you. SAP just released a trial version in de download section.
Example of ASIHTTPRequest
- (void)getFlightData:(NSString *) selectedDate {
     NSURL *url = [NSURL URLWithString:@"http://abap.sapdev.nl:8000/sap/resources/flights/from/%/to/%/date/20110128?sap-client=001"];
     ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
     [request setUsername:@"BCUSER"];
     [request setPassword:@"minisap"];
     [request startSynchronous];
     NSError *error = [request error];
     if (!error) {
          NSString *response = [request responseString];
          [self parseXML:response];
Example of KissXML
-(void)parseXML:(NSString*)source {
     NSError *error = nil;
     DDXMLDocument *theDocument = [[DDXMLDocument alloc] initWithXMLString:source options:0 error:&error];
     NSArray *results = [theDocument nodesForXPath:@"/asx:abap/asx:values/TAB/BAPISFLDAT" error:&error];
     for (DDXMLElement *flightdetail in results) {
          NSString *airlineid =   [[flightdetail elementForName:@"AIRLINEID"] stringValue];
          NSString *airline =     [[flightdetail elementForName:@"AIRLINE"] stringValue];

How to consume REST WebService using Axis2 in Adobe CQ5.5

Hi All,
    How to consume REST WebService using Axis2 in Adobe CQ5.5 ?
Please help me with this.Thanks very much for your help.
Thanks & Regards,
Kumar

We had enough trouble getting the "osgi compliant" Axis2 library to run in OSGI without spooky failures that we ended up re-writing everything utilizng JAX-WS. JAX-WS is present in the underlying JDK, you just need to create an OSGI fragment bundle that exposes these classes from the JDK. So basically a bundle that just exports:

How to consume an webservice in XI

Hi,
I need to consume an webservice in XI, can any one please guide me in this.
Regards,
Lakshmi

HI
I guess you want to consume webservice in webdynpro from XI , if that is the case
may be you can ask your XI consultant to provide you a WSDL url , and expose that as
webservice using adaptive webservice model and if you are using EP 7.0 you have to create Destinations
in the visual admin tool ->webservice security-> dynamic proxy
and if you are using CE 7.1 then you can create the destination in

I tried to consume webservice http://student.ohecampus.com/projects/group95/stud17/assignment7/validateEmail.asmx, which will return the data in boolean format. In this case, i am able to create a proxy and it is working fine. Can anyone help me out.
Thanks in advance.

Dear Raja,
I checked with webservice owner who created the webservice. They are telling that there is no problem in XML file which they gave. The webservice they provided is consumed in many application and it is working fine. When in SAP, i tried to create a proxy it is showing the in information which i mentioned in earlier posted forum message.
Kindly advice.

How to consume J2EE webservice in Oracle BPEL

Dear All,
Can any one please tell me that how to consume J2EE web service in Oracle BPEL. What is local registry. How am able to register my web service in to the local registry. Please suggest me.
Thanks,

Hi,
What IDE are you using?, for example with Eclipse i used WSDL2JAVA plugin in this way i converted the WSDL in java classes easily. Depending your development environment you can use different tools that makes easier the integration using the WSDL.

Doubt on Consuming webservices

Hi all,
I have a requirement to create a webservice from rfc and third party wantsto consume webservice from external system. I have created rfc and webservice from the same and got wsdl link. Can anyone tell how the external system can access wsdl link directly or is it required to register uddi ?
thanks and regards
Jijo

put the WSDL URL into your favourite webbrowser and see what happens. if you can see some XML on your screen, your browser is 'consuming the WSDL'. if you see some proxy information or anything else that says that the desired host is not reachable you have a network issue to resolve. Resolve the issue and your webbrowser (aka client) is able to consume the WSDL. The story is completely the same for any other kind of client.
No need for an UDDI. A UDDI is a phonebook, and usually you don't need a phonebook to make phone calls. It's the same for webservices and their descriptions(WSDLs).
hope it helps,
anton

How to consume a web service provided by third party system from SAP system

Hi Friends,
Could any of you provide me a clear picture on how to consume a web service from SAP system and is provided by a third party system?
Do we get an URL to create a client proxy for consuming the web service?
Thanx in advance,
Ram

Hi Ram,
of course you cannot supply the WSDL URL. Inside the WSDL (just view it in your browser) you find (usually but not necessary) towards the end something like
<soap:address location="http://www.weather.gov/forecasts/xml/SOAP_server/ndfdXMLserver.php"/>
which is the actual adress of the service.
An example service can be found here:
<a href="http://www.weather.gov/xml/">National Digital Forecast Database</a>
containing the WSDL URL at
<a href="http://www.weather.gov/forecasts/xml/DWMLgen/wsdl/ndfdXML.wsdl">this address</a>.
You might also want to browse for the amazon webservices which allow you to embed queries against amazon into your application.
have fun,
anton

Error in Consuming webservice proxy in SAP

Hi,
I have a webservice which I am not able to consume in SAP. I get an error 'Cannot generate Proxy (object <attribute name="arrayType"> missing in WSDL, see long text').
When i tried to search in SDN, I found a post which says that SAP doesnt support soapenc:Array types and it can be converted to corresponding Sequence. I went through the help link
http://help.sap.com/saphelp_nw04/helpdata/en/43/ce993b45cb0a85e10000000a1553f6/frameset.htm
which has a link which shows an example.
Accordingly, I have changed mine from:
- <schema targetNamespace="https://tserver.perfectcompliance.com/4DSOAP/LLX_Guardian" xmlns="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
- <complexType name="ArrayOfstring" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">
- <complexContent>
- <restriction base="SOAP-ENC:Array">
<attribute ref="SOAP-ENC:arrayType" wsdl:arrayType="xsd:string[]" />
</restriction>
</complexContent>
</complexType>
</schema>
To:
- <schema targetNamespace="https://tserver.perfectcompliance.com/4DSOAP/LLX_Guardian" xmlns="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
- <complexType name="ArrayOfstring">
- <sequence>
<element name="item" type="xsd:string" minOccurs="0" maxOccurs="unbounded" />
</sequence>
</complexType>
</schema>
After doing the above changes, I am able to consume webservice and create a proxy but it's not working. When i execute any method which is using the Arrayofstring, it gives me an error:
Complex Types cannot be parsed.
Is my above change in XML wrong. Do I need to do any other changes.
Regards,
Nikhil

Getting error while consuming webservices

Hi Colleagues,
In our application we are calling External webservice through WSDL file. I have deployed the WSDL files on server and get the WSDL URL using "WDURLGenerator.getAbsoluteWebResourceURL(wdComponentAPI.getDeployableObjectPart(), "file.wsdl")". I am able to call the service from WS Navigator.
I have consumed webservices uisng Adaptive webservice model and given the service group configuration ,created a provider system, assigned the provider system to the application through SOA Management-->Application Communication
Now when i tried to run the webdynpro application i am getting following error
Could anyone please let me know how to overcome this?
Exception i am facing is given here:

some configurations for consuming services using service group is missed out.

Consuming Webservice in WebDynpro - Content-Type issue

Hi,
I am getting a shortdump when consuming WebService in WebDynpro.
I trace it back to the class CL_SOAP_HTTP_TPBND_ROOT method GET_HTTP_HEADERS whereby the
value = 'text/html; charset=iso-8859-1' while the constants tsrc_soap_11_http_content_type = 'text/xml' ; tsrc_soap_bx_http_content_type = 'application/x-sap-bxml' ; tsrc_soap_mtom_http_cont_type = 'application/xop+xml' ; tsrc_soap_mp_http_content_type = 'Multipart/Related'. Because of this Content-Type difference my WebDynpro application dumps?
Any ideas how to solve this problem?
Thanks.
Regards,
Amel

hi,
Few indroductory sessions
/people/thomas.jung/blog/2007/12/17/consuming-services-with-abap -Consuming webservices with webdynpro.
It is possible to create webservice in ABAP as well as in Webdynpro.
ABAP Webservice:
http://wiki.open-esb.java.net/Wiki.jsp?page=BAPIWEBSERVICE
http://www.sappro.com/downloads/SAPXI.pdf
Webdynpro Webservice:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/244e7923-0a01-0010-5887-fe0b0c6dbb8d
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/30f1b585-0a01-0010-3d96-ad0ea291c4f9
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/media/uuid/db785a70-0701-0010-858c-eee0ec4fe1b3
In Web Dynpro ABAP there is nothing special about calling a web service. Unlike WD Java, there are not dedicated model object types in WD ABAP. WD ABAP simply has the ability to interact with other ABAP development object types. You can call function modules, ABAP classes, even modules in old dynpro apps.
So calling the webservice from ABAP therefore is just the process of generating the ABAP Proxy Class. This is the same process regardless of if you want to use this proxy class from WDA or any other type of ABAP development object. You can then call the proxy class from WDA just like any other type of ABAP class. There is a service wizard option in later support package levels that includes an option for ABAP Proxy classes - although it doesn't generate the proxy class it just generates the code and context for the call to an already existing proxy class. The service wizards in WD ABAP are not required however. They are just shortcut code generators and often can't even generate a complete context for a complex web service proxy - so expect to do some manual adjustment after running the wizard.
