Exception during calling SAP Web service

Hi,
I have exposed BAPI as a web service and trying to access that web service using
SAP Netweaver by creating CAF application service.
I have successfully get output from web service.
To get output for specific structure i have to provide empty structure of that in input.
This is working fine.
But for one particular structure when i am providing empty structure i am getting
"java.lang.IllegalArgumentException".
I have started BAPI in Debug mode and tested but from BAPI result is successfully delivered but when it received at
SAP Netweaver side it throws above error.
Please suggest how to find out exact problem.
I have checked log viewer also. I found only one entry about getting exception. no extra information is provided.
Thanks in Advance...

Flex2 call SAP Web Service

Hello all Experts
I create a web service from sap function. I test the web service with wsadmin and the service runs well. I'd like to use Flex2 to consume the web service for test. But I met compile error in Flex2. In my Flex application, I use <mx:WebService> component. Follow is my flex code.

When I try to compile the code, there is error called "wsdl" must end with the ';' delimiter. Does anybody know how to call sap web service in Flex?

Calling SAP Web Service from BPEL

Hi
I am trying to call a SAP Web Service friom BPEL using the SAP WSDL.It requires a basic authentication (Username/Password) which i am providing as partnerlink properties in bpel.xml.
While testing the BPEL Process from the console, it is giving me an error
"<summary>exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Bad response: 401 Unauthorized</summary>"
But when i am testing it from SOAP UI tool it is giving me the desired response.
Does anyone has any idea why it is failing from BPEL?Is there any configuration which i am missing?
Regards
Ayush

HI Ayush / Suryaveer..
I am stuck at the same situation, trying to invoke a secured SAP webservice. The invoke fails with a security previlege exception.
Am using the basicHeaders property to propagate the credentials to the SAP system.
Can you please suggest on the same.
credential propagation in bpel.xml :
<property name="basicHeaders">propagate</property>
<property name="basicUsername">ABC</property>
<property name="basicPassword">DEF</property>

Getting Timed out exception while calling a web service

Hi,
when i am invoking a web service(using routing), the osb proxy is getting timed out before receiving the response from routed service.
Also we are not aware of how much response time the routed service will take. so apart from increasing the connection time is there any alternate solution?
can any one suggest.

I do not think there is any other way apart from increasing timeouts to call a web service from OSB synchronously which is taking a long time.
Other alternatives are either to make the service asynchronous delyed request response type, which will mean a change at the backend webservice.
Ideally synchronous web services are designed to respond within a few seconds and not take minutes for processing. I would say that if the backend web service is taking more than a minute then they need to either tune their service performance better so it responds faster OR change it to an asynchronous service.

Exception in calling a web service from a composite application service

Hi,
I have created a composite application service with external service as a web service. My web service is deployed on localhost as well as I am running my composite application service in localhost. When i try to test the application service, I get the exception
com.sap.caf.mp.base.exception.InvocationException: Invalid parameters
The exception happens in MPConnector.java 'process' method where I am calling the execute operation on the service.
I have tried testing this through Service Browser as well as creating a callable object on the Application service and testing the callable object.
I am using the NWDS 7.0.06 version
and EP installed on my machine is the Sneak Preview 7.0 sp 7
Will appreciate all help in this regard.
Thanks,
Prachi

Hi Navneet,
I have verified the input/output parameters. They are simple types. All are Strings. Nothing really complex there.
I have the Service Exceptions added already.
And definitely the permissions are disabled but still this isn't working.
Any more clues might be helpful.
Thanks,
Prachi

SocketTimeout Exception while calling a Web Service from EJB

Hi All,
I am consuming a Web Service defined from the WSDL received from a PI system
in a Stateless EJB.
The input of the Service can be a range of records 100 - 10,000, with a furture plan to exceed the range as 100 - 15,000.
The Web Service Call goes perfect with 100 - 3500 number of records.
As the number of records exceed 3500, we started getting the following exception:
Service call exception; nested exception is: java.net.SocketTimeoutException: Read timed out
Along with a call happenning to the PI system after some seconds.
Referring to various help.sap.com pages, I came across the following code snippet:
client._setProperty("socketTimeOut","200000");
This thing works great!!!, and now we have set the the socketTimeout proggramatically to a satisfactory level which supports the current requirement.
I would like to know, if we can tune some Visual Administrator Parameter for this, instead of maintaining the "Socket TimeOut" in the code.
Any help will be appreciated.
Best Regards,
Alka.
Edited by: Alka Panday on Apr 23, 2008 9:17 AM

Hi Alka,
Please refer to SAP Note 962114. This is specifically for Web Service clients.
Description-->
This note can be applied for 6.40 SP 12+. If the customer has a lower SP, an upgrade of the whole engine is recommended. The other alternative to set the timeout is to set it programmatically.
If running a 7.0 installation, the functionality has been integrated in SP8 onwards
When you go to the Visual Administrator -> Server -> Services -> Web Services Container on the Settings tab page you should be able to see the socket timeout input field next to the HTTP Proxy settings. You can change the default value there and it will be automatically applied to all WS client proxies and logical ports deployed on the system.
Hope this helps.
regards,
Piyush

JDBC Exception while calling a web-service

Hi all,
We are getting the following JDBC Driver Timeout Exception while calling an external web-service..
An exception occurred while executing a transaction. Details: An error occurred while accesing the database.

How do we resolve this exception?
We have increased the JTA timeout to 120 seconds.. in the engine..
Our process is deployed on Weblogic Server

Looks like specific record for the Instance id 10 is locked in the Engine table. I am not quite sure, what kind of Business scenraio you executed to end up in this issue.
But you can try restarting the BPM engine or check with the Oracle DBA to see any lock on the rows in Engine database and perform required unlocking operations.

but when i am using my url at the end of step 3, i am getting error as follows:

thanks in advance

Hi SDS,
you recieved a http 404 error when trying to access the Sharepoint Web service. Http 404 indicates that the resource is not reachable (cf. HTTP 404 - Wikipedia, the free encyclopedia). There could be different reasons for that. I'd suggest rubble checking the URL of the Web service first. Try to access it from a browser on you desktop. If the URL is correc. Most likely the SAP system is not able to connect to the URL. This could, for example, be due to some firewall restrictions. You should ask a SAP Basis colleague if they are able to access the URL of the Web service from the server on which the SAP system is running.

Call a web service in an interactive form within SAP

hi experts
I need to call a Web service into an interactive form within SAP, but to do so fails to press on the button that calls the Web service, the strange thing is that if I keep the PDF in my PC, then open that PDF download button works correctly if I am doing something wrong?, you can do what I need?.
Greetings.

Hi asdasdasdasd1,
not sure if I fully understand your problem but it sounds like you are trying to execute your Web Service in the preview tab of LiveCycle Designer. When you do this, features of the Reader Extension Rights are not available so you will have to generate the form via the ADS and test the WS on the generated rendition as you have done.
Let me now if this helps.
Regards,
Ben.

Does any one have insights about it?

Hi Swapna,
from your screenshot it seems that you actually try to call the service in your Data Source Expression field. You should set path to the WSDL file here actually - this could be either URL to SAP or to filesystem, as Anton suggested (this could be faster). Have you created endpoint binding for your service in transaction SOAMANAGER? If yes, then simply download the corresponding WSDL with binding or copy the URL which leads to it. But also test whether you are able to retrieve the WSDL without logging into SAP (close all browser windows and then open a new one otherwise session ID from other browser windows can be reused).
If you have to give username and password, then setup anonymous alias in transaction SICF, for example.
Pleas, check my previous post on the same subject here: Re: BCM7 IVR : SOAP request for client identification in CRM .
Maybe it could help.
Regards,
Dawood.

QName error while calling a web service from Sourcing

I need to call a web service from Sourcing script. The web service team has provided us the WSDL and I have generated the required stubs using wsimport and packaged the required java classes in a custom JAR. Now while calling a web method using this jar from my script, I am getting and exception. The exception message that I printed out was this:
Caught exception e with msg Connection IO Exception. Check nested exception for details. (Connection
IO Exception. Check nested exception for details. (Connection Exception; nested exception is:
java.lang.IllegalArgumentException: cannot create QName from "null" or "" String).)
The same jar and same code works fine when called from a standalone java program.
I am not using or creating QName anywhere in my script. The only place where QName is used is in the generated java class and there it is created from the correct namespace URL
Can anyone please help me out in figuring out what is the issue?

This is the stack trace of the error:

I tested the same custom JAR, that is deployed in Sourcing, separately using a standalone java program and there it gave back the correct SOAP response
