WebService - Deserialization Fails

Hello!
When testing my Java Class based WebService with the web servie navigator, I get an error message:
"Deserializing fails. Nested message: XML Deserialization Error. Result class [myClass] does not have property [somePropertyName] of type [aTypeName]. It is required to load XML."
I found some hints pointing to Java as well as to SAP NetWeaver problems, but none of these shed any light on the problem. The class "myClass" does have a public property "somePropertyName" with type "aTypeName", the class does have an empty constructor without parameters, getter and setter methods are available for this property and there are no underscores anywhere around the whole webservice. Any hints ?

Further , These are the complete requirements for complex type object---->

Invoking BPEL process from ADF application - webservice connection failed

Hi,
I am trying to invoke a Bpel process from ADF page , I deployed the same in Standalone SOA server since I had to display some Human Task Forms.
I created a webservice data control out of the bpel process and dropped the process method in my page.
The page on which I dropped the process method stopped rendering and I checked the logs and found that I got the error mesage- webservice connection failed,the webservice url could not be reached and in the logs it also asks us to check if the connections.xml is available in the meta-inf directory. I checked the conections.xml is available in the EAR.
So any pointers here and any one faced this error anytime?
is there better ways to invoke the bpel flow from ADF page.
Thanks,
Robin

Hi,
Check if your wsdl endpoint can accessed properly. If yes, check the soap-binding address is properly pointing to the server hosting the webservice.

You were using the ReflectionPofSerializer coded by Alexey. If you are pretty sure that the object you retrieved was stored using the same serializer, might want to contact Alexey to see if he can help you out.

Deserialization failed

Hi to all
i have create a simpl .NET application in C# that call a web services in SAP. The call are in the next code:
MDM_SAP.Bapiret2[] myRet = new NBMI.MDM_SAP.Bapiret2[2];
myWS.Zmdm00AllCreUpd(CAP, CDC, CodDecreto, Divisione, Email, Fax, Frazione, IdSede, Indirizzo,
Lingua, Localita, MacroArea, Nome, Note, NumCivico, Nazione, Provincia, Regione,
ChiaveRic1, ChiaveRic2, StatoSede, ref myRet, NumTel, TipoPV, TipoSede);
When i try to test this WS raise an exception with the next message: "Deserialization failed " .
Why? Where is my mistake?
Thank in advance

Hi Enrico,
The deserialization error can be due to the following:
1. The web service WSDL or operation's signature has changed from what it was consumed in your client. You'll need to check this with the WSDL comparison and carry out the required steps.
2. There is underscore in the member variable names of the complex types used as the web service parameters. This problem is not clearly defined anywhere, but if you try to search in the [Web Dynpro for Java forum|Web Dynpro Java; you'll be able to find many threadsregarding the Deserialization error and solving it by removal of underscore.

Alka.

Deserialization Failed error when calling a SAP Webservice

Hello,
I'm trying to call an SAP Webservice from a .NET Mobile application, this particular BAPI expects an array of objects and when I make the call I get a deserialization problems. I have tried make the array size to 0 but no luck, I have couple of other function modules which are working fine but have a problem with this BAPI BAPI_ALM_ORDEROPER_GET_LIST.
any help is greatly appriciated.
Thanks
Vinay

Dear Vinay,
Does your other FM are also using arrays.?
Deserialization problem comes when xml parser is not able to convert XML schema or values to language specific elements.
And this problem normally comes if you are using complex data types.
Can you check once again and reply.

Piyush

Webservice call failed during execution (SSL and certificates) on NetWeaver 7.30

Hey experts,
i need your help!
We make webservice calls to sap me with our own software.
We connect to our software via SSL and certificates e.g. https://host:50001/XMII/CM/POD/MEDialogsWeb.irpt
At the beginning the software runs without any problems and than we become the following message on all our webservice:
thats the webservice configurations
(configuration - connectivity - single service administration):
(configuration - security - authentication and single sign-on)
if we restart the software after the error display, the webservice call runs successfully again.
is it a timeout?
can anybody help us?

Hi,
the authentication for the second call is failing. Have you tried suggest log level from note 880896 - Web Service authentication failure? I would also try to use something like SoapUI to test if the issue is caused by your application or something wrong on SAP side. Also coparing messages for the first and second calls might give you answer.

Webservice deployment failed

Recently I decided to make a webserver along my "currentdensity.vi" design to have access to the data through explorer. I read the instructions for configurations of webserver but I have still problem in correct implementation of it. I am afraid I have left some simple steps or hints to successfully accomplish it. (http://localhost:8080/webservice1)--->but no result displayed
Please give me your feedback.
Solved!

Hey Kira,
we just have one Web Service in place.
So only this one causes us problems.
We never have any trouble with the build process. The problems starts when trying to deploy.
Actually, I mentioned earlier that sometimes a restart of the computer solves the problem but not always.
Just now it is one of the rare moments that the webservice could be deployed.
However I think that this does not mean that from now on it will work stably. So right now trouble shooting is compromised as the problem has not occured.
But what should I do when it will happen next time? Plenty of computer restarts cannot be the solution.
I followed your advice and took a look under Start»Control Panel»System and Security»Administrative Tools»Services.
I did not find any service named NI Application Web Server there. In the task manager the is the process "ApplicationWebServer.exe" (while the web service is currently running).
When the deployment fails the progress bar does not go further than two bars. When to my surprise the deployment just worked I could capture a screen shot from the deployment progress window. I attach it to the post. Maybe this helps to find out why the deployment so often does not work.

WSDL deserialization failed!

Hi,
I'm trying to consume a webservice provided by an AS Java Server on an application running on my server, also AS Java. While executing my application, i got an error explained mainly by:
Caused by: com.sap.engine.services.webservices.espbase.query.exceptions.TechnicalException: Deserializing xml stream http://<host>:<port>/bpem/testsapcom2Fglx2Ftutorial2Fpm22FPool2FPurchaseProcessContinuation1258a3ef18c4b6a9bec22e5a9cb4abef?wsdl&mode=ws_policy failed.com.sap.engine.services.webservices.espbase.wsdl.exceptions.WSDLException: Read timed out
In fact, when i'm entering the url in my browser, i could read the WSDL without problem.
Could someone help me on that, and tell me where is the error and what to do to fix that. Thanks a lot.
Best Regards,
Jean NKENG

I found the solution Tamara. In fact, when i changed the computer full name by the IP in the WSDL url, (if i understood) it seems like the WS host corresponding to the IP i entered was acting like a proxy or something like that, trying to reach another computer, this is why the connection timed out, and because it is the host, it normally doesn't need to reach another computer or server.
The solution is to keep the computer full name in the WSDL, but add the ip address corresponding to the computer full name in the hosts file of windows, located by default here:
Windows NT/2000/XP/2003/Vista: %SystemRoot%\system32\drivers\etc\hosts
Wiki page: http://en.wikipedia.org/wiki/Hosts_file.
Just add a line to the file:
<IP address> <Computer Full Name> (Separated by tabulation)
Cheers,
Jean

ActionScript 3: WebService calls failing

Hi guys,
I am working on a Flash CS3/AS3 application that calls a server-side web service to retrieve/update data in the database. The code is simple and it works
great. However, some users are reporting that while browsing through this Flash application their web service calls are failing and thus no data gets
stored in the database. I am assuming probably a connection to the server gets lost while they are browsing. In this case the fault function also isn't
called. Is there a way to detect this kind of error? Should I check and reinitialize the web service before making another web service call? Does anyone
have any clue of what might be happening? Below is my code. Let me know if I am missing anything in the code.
Thanks
Code:
var ws:WebService = new WebService();
ws.wsdl = "http://localhost/Service.asmx?wsdl";
ws.addEventListener("result", resultHandler);
ws.addEventListener("fault", faultHandler);
ws.loadWSDL();
ws.RetrieveData(id);

Hi Roger,
I am experiencing a similar situation where a flash CS3/AS3 application using a similar code is calling a server side web service to retrieve/update data in the database. For some reason either a connection to the server gets lost or the web service call isn't successful and thus the fault function isn't called. Since you have asked this question a while back, I just wanted to know if you were able to resolve this issue?

WebService Call Fails for Communication Users

Hi
I am calling a BAPI through web service in VB.NET windows application.
The application works fine with Dialog users but when I use Communication User then it thows this message.
The Request Failed with HTTP Status 401: Unauthorized
Where as if i call the same BAPI through RFC with for this Communication User it is successful.
What can be the reason ?
Regards
Rajendra

The Web Service uses the HTTP protocol, whereas the BAPI is using RFC protocol.
The reason for the "unauthorized" error in HTTP is that you need to embed the user / password combination into the web service URL (assuming you have set the Web Service authentication method to user / password).

D.

WebService serialization fails

Hi,
I'm not sure if this is a bug or a compatibility issue...
When I compile the same code in Flex 3 to call a web service
as I used in Flex 2, the web message (viewed in Fiddler) includes
namespace definitions on each node in the header which are not
there in Flex 2. (Example below)
This means that when the message hits the server it won't
deserialize.
Using Fiddler I can remove the namespaces and resubmit the
request and it works.
Is there some new functionality in the Flex 3 SDK to specify
whether the namespaces should appear or is it a bug?
eg:
Flex 2:
<?xml version="1.0" encoding="utf-8"?>
