Accessing XI web service from portal as client

Hi all
I need to access a web service which has been created on XI
server. I want to acess it from enterprise portal as a web service client. please provide related links to achieve this.
thanks in advance

Vaishali,
never did this before, but some general ideas:
Do you have an WSDL for that web service? Then simply use your NWDS and select New --> Portal Service --> From WSDL (or similar). What I mean is the following: NWDS can read WSDL files and will automatically generate a proxy for you that actually generates an ordinary portal service. This portal service then can be called by standard means in SAP EP.

Problem in accessing a web service from a desktop client

hello,
i have deployed a webservice on JSAS 9.1 and i test it, its working fine.
then i create a client by using netbeans IDE6.0. the client is a simple java class and i make it webservice client. then after compling i run the client it works fine.
but when i try to run the .jar that the IDE has made after compling the client application, the program close on the statement where i made the Object of the service (i.e. CircleService service = new CircleService();)
try{
CircleService service = new CircleService();
Circle port = service.getCirclePort();
double r = 10.0;
double arearesult = port.area(r);
The webservice is properly deployed as i have tested it from the JSAS admin console.
Can anybody tell me whats the problem? Is there any security issue or someother issue.
null

i have tried the stack trace in the catch but as i said on the statement where i made the object for the service the program just exits. it didn't return any exception or any output.
thanx for refering me any answer.......

I am using Tomcat 5.0.19 . Could anyone suggest a possible solution to the same?
The system works fine when I use a http endpoint.

Hi,
By default, your application tries to connect to the Net directly : if you have to specify a proxy, use either these lines in your code :
System.setProperty("http.proxySet", "true");
System.setProperty("http.proxyHost", "proxy");
System.setProperty("http.proxyPort", "8080");
Or specify them in the command line with the "-D"option.
Ex : java .... -Dhttp.proxySet=true .... MyApp
Hope it helps.

Access a web service from pl/sql

I am trying to access a web service from pl/sql. I have downloaded the code from

Hi All,
I am a java developer. I am new to SAP. I just want to know how to use the web services from ABAP
I got the WSDL, and able to convert the WSDL into java classes using java2wsdl command.
Now i want to know how to use these classes, in my java class. i want to know two things
1) How to get authentication or session or token to use the service
2) How to consume BAPI services by using above session or token.
Any help, really appreciated. Plz help me if any one knows.
Thanks alot,

Hi,
I have a web application developed with java,jsp and javascript and server used is weblogic.
Now this application is running fine on my PC. I assume from this that there is no client side Java. Is this right?
So what steps are required so that I can access the application from other PCs also.If there is no client side Java then you have to do nothing other than make sure your PC can be reached from the other PCs. i.e. no firewalls blocking the access and routing available between the client PC and the server PC.
I don't see what this has to do with JNLP. Am I missing something?

Call web service from portal/soap config .xml error

Hi all,
I am trying to call a web service from our portal. Setup is as follows:
-Generate proxy classes and deploy it as a portal service
I created this service using the wizard (Portal service from wsdl file client side) in NWDS.
-Portal component which uses the portal service.
When I try to run the application in the portal, I get the following exception:

Hi,
Check your soapconfig.xml
Your method should be defined there. If it's not there, then you're sure to get this error.
For every method (in Webservice) that you call from your Portal Service, you should have it defined here.
Remember, this is autogenerated.
<?xml version="1.0" encoding="UTF-8" ?>
- 
- 
- <portal-webservices version="6,0,3" application-name="TestWS">
- <portal-webservice name="com.company.mod.TestWS">

How to access/invoke Web Service from BPM Process

The following steps required to attach and invoke web service method from process:
1) Add a module in the catalog for ex WebServiceMO
2) Add WebService Catalog component demoWebService in WebServiceMO
3) Put ur WSDL address in WSDL address field like "http://localhost:8080/test/test?wsdl"
4) Click next to introspect the web service it will import required files and setting from the url to your project
5) Now for invoking webservice just call the method for ex.
@return as String[]
getTestStringList(TestInterfaceService, out @return : @return)
logMessage "web service calll result >>"+length(@return)+">>>"+@return[0]
Here @ return is the return from webservice call.
this way u can access web service from BPM process.
Edited by: Anurag Yadav on Jul 17, 2009 2:19 PM

I have a web service which does not return any value but when I introspect the web service, I have an out parameter to it.. Not sure why?
For e.g.
TestServiceListener.addTestNotes(TestNotes : testNotes, out TestNoteResponse : testNoteResponse);
So here I see an out parameter, but my web-service has no out parameter...
Any idea why is this happening?

Problem with accessing a web service from outside world

Hello SAP experts
I have a custom BAPI for which I have created a webservice.
If I login as an admin to the BOX where I have installed this SAP server and open an internet explorer window and give the URL, I can access the web service without any problem. This is just a simple BAPI that searches for some data from a table based.
However, when I give the same URL from a different PC, it can open the web service and in the fields if I give the data and click on send button, it fails with an error '500 Internal Server Error '.
I looked for the details of this error on internet and it says that this is some general error and solutions that it suggested doesn't help my scenario.
Has anyone seen this problem before? Any help will be highly appreciated.
Tks
Ram

i have tried the stack trace in the catch but as i said on the statement where i made the object for the service the program just exits. it didn't return any exception or any output.

Access to Entity Service from Portal Application

Hi Experts,
I have a hybrid application which will be making use of both Web Dynpro and Portal Applications. I decided to use Entity Services to store my back-end data and can access it fine from the Web Dynpro project. I have included the public part of my CAF project into the Used DCs of my Portal project and while I am able to call the methods of the Entity Service at compile time, at runtime I receive an error message on the page:
An exception occurred while processing a request
I know in order to get this to work for Web Dynpro I had to include sap.com/tccolapi.sap.com/cafruntimeuicouplingapilib as a Library Reference and a few Used DCs, but while I have added the Used DCs to the Portal project, I am unsure of how to add the Library Reference. I assume this has to be added to portalapp.xml, but I don't know the syntax.
Could somehow please reply with how to do this and whether this is all that is required in order to call Entity Service methods from Portal applications?
Thanks,
JP

Hi Smith,
Write click on the Project then goto the Properties=>Webdynpro References=>Library references
add
caf/eu/gp/api
sap.com/cafruntimeuicouplingapilib
And add the following DC in your project.
1> External in caf/eu/gp/api (CAF domain)
2> caf/eu/gp/api/wd (CAF domain)
3> com.sap.security.api.sda (SAP-JEE)
portalapp.xml

HTTP error when trying to access RESTful web service from application

Hi,
We are getting the following error when trying to access a RESTful web service coming from Apex workspace 4.2.1 and Apex listener 2.1:
ORA-29273: HTTP request failed ORA-06512: at "SYS.UTL_HTTP", line 1130 ORA-29024: Certificate validation failure
In the Debug report, besides the above I also see:
error_backtrace: ORA-06512: at "SYS.UTL_HTTP", line 1130 ORA-06512: at "APEX_040200.WWV_FLOW_WEB_SERVICES", line 543 ORA-06512: at "APEX_040200.WWV_FLOW_WEB_SERVICES", line 1164 ORA-06512: at "APEX_040200.WWV_FLOW_PROCESS", line 396
We get that error whether we use https or http in the URI pointing to the web service. When I test the Web Service in Workspace RESTful service GUI, I get the data back. When I go build an application with a report calling the RESTful Web Service I get that error. Both the Application and the Workspace RESTful services are on the same Apex environment and even the same workspace.
What is odd is that I can actually put the URL of the web service into a browser and I get the data: (using the demo hr data in sample RESTful services.)
IN browser-- https://weblogic-dev.edu/apex/ace/hr/empinfo/

Any ideas on what would be causing the Error above in our application?
Thanks,
Pat
Edited by: patfmnd on Mar 11, 2013 3:25 PM
In reviewing the above error, I think we are realizing that we have to have the Weblogic layer SSL cert (actually the CERT from our BigIP load balancer which also does our SSL termination) imported into the Oracle server wallet where Apex is installed. Am I correct?
PM

We resolved our problem. The Apex Administrative Guide made us realize that we had to set up Wallet path in the Instance. This required working with DBAs to follow the Advanced networking guide to get the wallet set up on our server. We then added that path to the Instance configuration. (Manager Instance --> Instance settings). We ran into another other issue related to our implementation of CAS but were able to resolve that, and 'voila' were able to get the sample RESTful service consumed by our application!!
Now to the task of figuring out how to get Basic Auth working between client application and RESTful web service. If anyone has that working, let us know!!
It would be helpful if in the documentation of the Apex 2.x listener or Apex install/configuration there was clear reference to the above steps required for HTTPS access to RESTful web services.

Accessing a web service from an applet

Using NetBeans 5.5.1, I have created a web application consisting of a web service, an applet and a jsp. The applet is the client of the web service. The application is deployed on Tomcat 5.5.17, which comes with the IDE. Since the web service and the applet reside on the same server, I do not need to sign the applet to contact the web service�at least that was what I thought. Asking for the jsp in my browser, however, results in a java.security.AccessControlException:
access denied (java.util.PropertyPermission xml.catalog.ignoreMissing read)
To my best knowledge, my applet is not accessing local resources or doing other things that require it to leave the sandbox, so I don't understand why it needs extra permissions. Could it be the generated web service client code that is causing the exception? What is it doing that it needs extra permissions? By bundling everything in one application, I was really hoping to avoid having to sign my applet...

I performed some additional tests and it appears that when processing XML, java classes under the hood often need access to PropertyPermissions, ReflectPermissions, etc. So although your own code does not need to step out of the sandbox, system classes do. For example, try to create a JAXB context in an applet: unless you sign your applet or change your policy file, it will not work. Something to bear in mind when developing applets or deploying applications via JWS.

Slow response when calling a web service from an ADF client in JDev 11g

I have generated a web service (WS) for a stored procedure package with 3 functions. The WS has less than 1 second response times when I use the standard WS testing facility. I then created a data control for the WS selecting the default values in the JDev wizard. When I test the functions from a very basic ADF client the response times for the same functions are between 3-4 seconds i.e. very SLOW compared to the actual response time of WS. I need some advice on how to investigate this performance degredation as seen from the ADF client.
Could the problem be that the data control was created from a web service in the same project? Maybe it is necessary to have them in separate projects or create a proxy?
I created and tested the web service with the standard WS test tool and then simply went on to create a data control from this web service for use from a ADF client.
Some background info:
I saw the following warning in step 8 of the WS creation wizard:
"The configured policy store location at "C:\Oracle\Middleware\jdeveloper\j2ee\home\gmds" is invalid. Application cannot read policies from this location. Check that the directory name is correct and the location exists."
Also I can confirm that there is no j2ee directory in my environment.
The application server logs the following for each call from the ADF client:

Find solution. Check this thread:
https://www.sdn.sap.com/irj/sdn/wiki?path=/display/wdjava/faq%2b-%2bmodels%2b-%2badaptive%2bweb%2bservice
The com.sap.tc.webdynpro.model.webservice.api.IWDWSInvocationModifier interface can be implemented by an application using the Adaptive Web Service model in order to modify the web service invocation object just before it's execution. Invocation modifiers need to be registered with the executable model class for which invocation is to be modified:
Request_NumberToWords requestMO = new Request_NumberToWords(model);
requestMO.wdSetInvocationModifier(
new IWDWSInvocationModifier() {
    public void doModifyInvocation(Object port) {
      HTTPControlInterface httpItf = HTTPControlFactory.getInterface(port);
      //timeout for this WS invocation is 120 sec; don't use global config. setting of WS-Runtime
      httpItf.setSocketTimeout(120000);
    public void doModifyAfterInvocation() {}
Best regards.

Calling web-service from non-SAP client

Hi,
Could anyone here help me with the code with which we can call the non-SAP service in java from a java client.
I have the wsdl and service deployed on the server.
Regards,
Manoj

Hi Eduardo,
We are trying to consume a non-SAP webservice (https based) which uses a certificate issued by the non-SAP web service provider for authentication.
We tried consuming the web service using the Web Dynpro Java's Adaptive WebService Model method. We configured the Logical Destinations with X.509 client certificate authentication and have added the certificate to the WebServicesSecurity keystore.
However, when we run the application, we get the 'Peer certificate rejected by ChainVerifier' error.
Could you guide us on how to resolve the same ? If possible would you also provide the step-by-step details of how to create the EJB application that you did to achine this ?
Any help is greatly appreciated.
Thanks.
Melwyn.
