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.......

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.

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

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 the Web Service using standalone Java Client

Dear Friends,
Hi,
I have an active web service and I have tested the same with XML Spy and Apache Axis and is giving me the output perfectly. For the same, I have developed a standalone Java client but getting problem in fetching the output.

I appreciate you all for helping me out of this.
Thanks

Hi Amit
We also have this issue with weblogic webservices. Did you get any resolution for this issue.
When the service is executed for lesser number of hits, all the responses are processed properly. But as load (Number of hits for the same service) increases, few responses are failed to be parsed in the web service client. We could confirm that the producer responds with proper content type (text/xml)
Any help or pointers will be greatly appreciated.
Thanks,
Finny

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.

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?

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?

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:

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.)

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.

Problem invoking UCM 11g Web services from ODI 11g

The problem occurs when we invoke it from the ODI assistant, when we type the WSDL URL and click in "Connect to WSDL" button,
we get the following error in the middle pane : Invalid Request : java.lang.NullPointerException+
The port combo and the operation pane are correctly populated
UCM version is: 11gR1-11.1.1.6.0-idcprod1-121115T130554 (Versión Interna:7.3.3.183)
ODI version is: 11.1.1.6.0
Java(TM) Platform 1.6.0_30

I would suggest contacting support channel to analyze such NPE if there is a product bug causing it.

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.

Accessing BAPI web services from CAF External Services

We have wsdl files that corresponds to BAPI calls. Using CAF, we want to create an external service using those wsdl files and then create an application service which will be in turn used by web dynpro for developing our composites. We did the following steps:
1. Created a new Composite Application Service project
2. Then right click on the External Services, select import, choose Web service.
3. Select 'Local File System or URL' option. Copy the URL from the wsdl file and pasted the URL in the 'Browse' text field and click Next. Got an error in loading the web service.
4. Removed the Proxy Server settings in Developer Studio but in vain. Tried all possible combinations with the URL also (such as with and without the wsdl key at the end of the URL and using the 'UDDI or URL' option under the Proxy Definition of the External Services Import and also with the Window => Preferences => Proxy settings).
5. Since the above options failed, copied the wsdl files to the local drive and then choose that WSDL from the file system. Able to import.
6. Created the application service and provided the custom code for the request and response.
7. Registered the external service in the CAF browser -> Administrative tools -> External Service Configuration
8. Tested the service through the Developer Studio.
The error I get is: ERROR: IOError while working with the message. Check the nested exception: Connect Refused: connect:
Any idea on what needs to be done to resolve it?

authentication is required at design time to read the wsdl from bapis. did you provide username and password when importing the web service.
you can always add the username and password to the url to see if you can successfully get to the wsdl. Like that http://<webas_abap_servername>:<portnumber>/sap/bc/soap/wsdl11?services=BAPI_PO_CREATE&sap-client=<clientnumber>&sap-user=<username>&sap-password=<password>
