Closing stateful web service connections

Hi All,
I've created a staeful web service(in ABAP) and we are doing load tests for 50-100 concurrent users on this webservice.
After some time we are getting invalid response time exceptions while calling the web service.
In transaction SM04 , we observed all the (HTTP connections)stateful connections are opened and after reaching 1000 users its anot allowing further webservice calls.
How can we close the staeful web service connections . I am cosuming this web service in java.
I've created standalone proxy .
Please let me know.
Thanks,Anilkumar

hi,
this is a very interesting question. Since I didn't know how the WAS ABAP actually supports stateful webservices at all I did research it a little. It seems that there is no standard for stateful webservices in existence (yet?). So there seem to be two mechanisms actually used to maintain session (in the world not SAP), one by (mis)using WS-Adressing and the other one by simply using HTTP sessions (cookies). Using WS-Addressing would be reflected in the WSDL which isn't the case (Rel. 7.0). So this must be achieved by HTTP session cookies.
In HTTP session management there is, AFAIK, no mechanism to allow the client to explicitly close a server session. Usually the client destroys it's session and the corresponding server session simply times out because it is not called for a certain amount of time.
Second, IMHO, such a session is not much good for (apart from getting rid of successive authentication) as long as the application cannot access the session information. I am not aware how a function module underlying a webservice can access this session information.
In conclusion, I would be very interested if you could share a bit on how youse stateful connections and what you can achieve with it.

Stateful web service implementation in Flex 2

Hello Gurus,
We are trying to invoke a web service located on a remote
server using MXML to create a purchase order. One of the
requirements is that we pass a cookie from our end to this web
service for authentication and session management purposes. Can
anyone throw some pointers on passing cookie information to
webservices from MXML or ActionScript?
A little bit of research resulted in the following link:
http://livedocs.adobe.com/livecycle/es/sdkHelp/programmer/lcds/wwhelp/wwhimpl/common/html/ wwhelp.htm?context=LiveDocs_Parts&file=rpc_26.html
An extract from the above document states the following:
"Stateful web services
Flex uses Java server sessions to maintain the state of web
service endpoints that use cookies to store session information.
But unfortunately there are no examples on how to pass the
cookie information itself. Any pointers are appreciated . Thanks
much!

This issue caused me much confusion and delay, so I hope that what I am about to say is correct. When Flex calls a web service that requires a stateful connection, the web service "cookie" is stored in the browser. Flash automatically attempts to access this cookie value, and returns it to the web service when additional web service operations are called. The cookie value will be placed in the "Request Headers".
A couple issues that gave me fits:
1. Safari browser on Mac had default "/preferences/Privacy/Block cookies" set to "From third parties and advertisers". This was preventing the cookie from being sent. I had to change this setting to "never".
2. I work inside the Flash API. Testing my movie never passed the cookie value back, and I have not figured out how to do this when compiling for Flash Player.
- NOTE: I am able to test compiling as an Adobe Air App just fine. I did this to get my web service calls/parsing of returned info correct first. Cookie issue and Cross Domain issues are not issues in Adobe Air, so I find this is a good place to get the web service working. After working compiling as Adobe Air, switch to compile for Flash Player to fine tuning other issues.
3. Cross Domain issues. Lots of posts on this. Pay close attention.
Thanks!

"Unable to load URL" - SQL Server 2005 DB Web Service Connection

Hi ,
I am using XCelsius version 5.0.0.99 to create dashboards connecting to SQL Server 2005.
Find below the details of the steps -
1. Created a web service within SQL Server 2005 database.
2. Copied the WSDL URL.
3. In XCelsius 2008 -> Data Manager -> Web Service Connection, pasted the URL in the WSDL URL input box and clicked "Import" to import the methods. At this point I am getting "Unable to load URL" .
Am I missing any step ?
Any suggestion would be highly appreciated.
Note : I have tested the web service by using it in a ASP.Net project and works fine.
Thanks
Chitra

Hi,
Error :unable to Load URL occurs" because Crystal xcelsius only support single schema web service created from Query as a web service and Flynet tool available in xcelsius 2008.
The reason:
All the web service create from Sql 2005 ,PHP script produced multiple scehma web service and crystal xcelsius only support single schema web service which can be created from Query as a web service or Flynet.
Please revert in case of any queries.

Need help calling stateful web service from BPEL 10.1.3.1

I found the tutorial located at http://www.oracle.com/technology/products/ias/bpel/htdocs/callingstatefulwsfrombpel.html which talks about how to call a stateful web service, it is also mentioned on Clemens Utschig's SOA blog.
The problem is that the code for the handlers will not compile as given under 10.1.3.1 -- it seems that the method signature for the invoke method has changed in the interface com.collaxa.cube.ws.HeaderHandler
Has anyone gotten this to work in 10.1.3.1 or can anyone give me a tip on how to call a stateful web service in a different manner from BPEL?
Thanks!

Consuming a stateful web service

We created and deployed a stateful web service(mail service) in J2EE. It is tested working fine for J2EE consumer. Now we need to create a client from SAP WebAs (abap side). We generated the proxy with logical port, having set those "State Management" and "Session Oriented-communication" features, which I believe supposed to be stateful.
But the program crashed at the second time I call any method in the client proxy, for example, after "CALL METHOD mail_proxy->open_mail_session" to open a mail session, the "CALL METHOD mail_proxy->open_mail_store" throws an exception: "ICF Error when receiving the response: HTTP COMMUNICATION FAILURE". It doesnt matter which method I used, it crashed on the second one any way. If I move the second method to the first call, the method will work fine but still crash on the 2nd called method.
I need more information about how to make the client proxy and logical port working with a stateful web service.
I will appreciate any hint, reference or suggestion!

Hi,
I am also creating a stateful web service for a standalone java client..
Do we need to set the SESSION_MAINTAIN_PROPERTY on the client stub.It gives me a remote exception once I use this.Dont know how this web service keeps track of session..Pls advice

Mapping input values for a web service connection to a range of cells

I've created a web service connection in Xcelsius data manager. My web service requires an array of integer as input parameter. How do I map input values for a web service connection to read from a range of cells in the spreadsheet, e.g. $A$2:$A$20, in similar way of mapping output values to write to a range of cells in the spreadsheet?
For output values of the web service, I can specify to map the output values to write to a range of cells. However, it doesn't seem to work for reading the input values.
I can map input values for each node to a single cell, e.g. $A$2, in the spreadsheet. However, when I set the "Read From" field to a range of cells, e.g. $A$2:$A$20, it only reads in the first value in the range.
Is there any way that we can do this mapping for input values as we do for output values?
Your assistance is very much appreciated.
Regards,
Van

Van,
There is a workaround for that...
Example:
My Webservice accepts input data range in a specific format with " :" symbol, i.e. 072008:082008
Now what i do is
A1 = 072008
A2 = 082008
A3 = CONCATENATE(A1,":",A2)
so A3 = 072008:082008
Now i map the input value in web service to cell A3
P.S have 2 input box components and map it to cells A1 and A2, i.e you are giving users an option to enter the range of values...then web service will capture the range and refreshes data with the range of values user entered.
hope this helps..

Difference beetween QAASW and Web Service Connections

Hi everybody,
I'm trying to install a connection between Xcelsius and a QaaWS I created, but it doesn't work. In the list of the different connections available in the Xcelsius Connections Manager, the "QaaWS" connections doesn't appear. Instead of that I can choose the "Web Service Connections" type.
Do you think this little difference can't be the source of my big problem?
If not, do any of you would like to risk an explanation about this odd pheanomenom (which seems to belongs to the category of the surnatural things thats happens when I even try to undertake a slight complex task in my Business Objects environnment)
In advance , thanks a lot ( why "in advance"? Because I feel, I'll get an answer, as an old bohemian woman who's suddenly poped in my office today told me one you would light the darkness of my interrogations)
Bye bye !!

Hi Meryll,
As you have already noticed, invoking a QaaWS URL into the standard Web Service Connection will NOT fire, regardless if everything is configured correctly.
I would assume that this is by design due to the fact that QaaWS Web Services are fetching data out of a BOE server. As such, anything that has to do with BOE connectivity (LiveOffice, QaaWS, Open/Save/Import/Export to Enterprise) is only available in the Xcelsius 2008 Engage Enterprise edition.
Thanks.

Dynamic columns on output values for a Web Service connection

Hello,
I'm trying to create a web service connection that is similar in response to the XML data connection in that i don't want to fix the number of columns per row down in the WSDL. i.e. i want to create an array of columns:
<xsd:complexType name="XLRowDef">
    <xsd:sequence>
      <xsd:element name="column" curashared:shortname="c" type="xsd:string" minOccurs="0" maxOccurs="unbounded"/>
    </xsd:sequence>
</xsd:complexType>
and for the user of the WSDL (the guy who will design the dashboard) to be able to fix and link the number of columns when he designs the dashboard. I was hoping the button would reveal itself in the "output values" box much like it does in the "input values" but no matter how i twist the xsd - no joy. I also tried just linking the column element to multiple excel columns but still fixes to the first column in the range. Can this result be achieved in Xcelsius short of using an XML data connection?
Regards,
Gilbert

Calculations in Xcelsius using data generated by a Web Service Connection

Hi,
I have set up a web service connection to pull in 4 columns of data: 1. CATEGORY 2. SUBCATEGORY 3. PRODUCT TYPE   4.#OFCALLS. There will be anywhere from 1 to 500 rows of data depending on day of week and time of day. The web service sorts the list by #OFCALLS descending. The OUTPUT VALUES of the web service connection are mapped to cells A19:D518.
Formulas in the spreadsheet take the Top 10 from the list and populate it to cells A4:D13. A formula in cell D15 sums the #OFCALLS for the entire web service connection output (A19:D518).
The data in A4:D15 is mapped to a spreadsheet table on my canvas.   When the report generates, the data from the TOP 10 of the web service connection populates properly, but the cell that should reflect the TOTAL#OFCALLS (D15) shows zero.
Is it not possible to do additional calculations in the spreadsheet based on data generated by the web service connection? A major difference between using an XML Map and a Web Service Connection is the XML Map actually populates the spreadsheet with the new data when it is refreshed. The Web Service connection data never actually appears in the spreadsheet itself, even though it updates to the appropriate vessel on the canvas.   This makes me think that no additional calculations can be done in the spreadsheet based on the web service connection data.
Can anyone tell me if that is correct? If so, then the web service connection would also have to pull in the TOTAL#OFCALLS along with the other data.   This would also seem to greatly limit what you could do with data generated by a web service connection, so I am hoping I am wrong and just don't understand how to do this.
Can anyone clarify this for me? If I failed to give any pertinent info let me know what it is, and I will update my post.
Thanks!

I have seen similar behavior as well. I have live data coming into Xcelsius from a data connection.
A supported Excel formula
=IF(ISBLANK(J2),I2,VALUE(TODAY()-J2))
is then applied to one of the columns to create an additional derived column.
Taking a snapshot of the data shows that the derived column is being populated, however the controls I've tried hooking up to the derived column (charts and labels) are always empty.
Information on whether this is supported would be appreciated.
Thank you,
David

Error with web services connection to B1 DI API

We are attempting to utilize the web services connection to SAP Business One and are running into difficulty. Below are the particulars:
-   We are attempting to make a web services connection to B1 using PHP on Linux.
-   We are able to establish a session, but not able to make a successful web services request.
-   The attempted action is to add a Business Partner
-   Error we are receiving:
SoapFault exception: Not Found in /var/www/test.php:83 Stack trace: #0 : SoapClient->__doRequest('__call('Add', Array) #2 /var/www/test.php(83): SoapClient->Add(Array) #3
-         We are also able make a successful web services request to the same B1 server using ASP from Windows.
-         Once we establish a session through PHP / Linux, the DI Server will not respond to either PHP or ASP on Windows
Any advice or suggestions would be appreciated.

Russell,
Since you are getting a "SoapFault Exception", you must be trying to use SOAP messaging. The DI API does not understand SOAP messages. You would need to use the DI Server (SDK Help has information on DI Server) for SOAP based messaging and in turn you may also want to look at the Business One Web Services (B1WS) tool that s located in the Tools section of the SAP Business One main page here on SDN.

Slow response when using Xcelsius web service connection witn input values

We've been very successful in using the Xcelsius Web Service Connection. We've recently moved forward toward using input values when calling a web service and having issues with response time. Without input values, it takes 3 - 6 seconds to retrieve and display the results in Xcelsius, but, when using the input values to the web service, it takes about 27 seconds for Xcelsius to retrieve and display the results. Does anyone have experience with fixing slow response associated with using input values for a web service connection?

Hi Sharone,
What's the version of your Xcelsius and BOBJ server?
I'm asking because using the last version of BOBJ server (BOXI 3.1 SP 3) you have new services on CMC just to help Xcelsius to work better with WebServices.
Regards,
Rodrigo.

Web Service Connection in Xcelsius 2008

I have recently upgraded from 4.5 to Xcelsius 2008 and am having trouble getting the Web Service Connections set up correctly for my QaaWS.
I have 7 LiveOffice connections in a model that seem to all refresh on load fine and i have already set up a Web Service Connection that picks up the drill through path of what the user has clicked on and used them as input parameters to a QaaWS query.
I now need to add another Web Service Connection for another QaaWS and i get the following error message;
"Unable to Load URL"
I have checked the available QaaWS services using dswsbobje/qaawsservices and the 2 queries appear as i would expect.
I have checked the dsws.properties file and the user name and password are correct (which i would expect as teh 1st connections works in the Xcelsius model.
I have restarted the Tomcat server and CMS and this does not cure the problem.
I have even tried re-installing QaaWS.
I have installed SP1 fix 1 for 2008. I am currently using XIR2 SP2.
Can anyone help as sometimes this functionality works and sometimes it does not. The 2 queries i want to use point aty teh ssame database and BO Universe.

Hi Anthony,
You might check that type of the licence type of the user QaaWSPrincipal. I had a problem where the QaaWSPrincipal user was Concurrent Access License while my server was Named User only. Switching to Named User resolved the problem.
However, I am not sure that this is your issue as the you have one QaaWAS url working. YOu might want to check your URL is available
try
http://<name of server>:<Tomcat port number>/dswsbobje/qaawsservices
This contains a list of all URLs. Finally, you might look at importing the wsdl into other applications to see if the issue is Xcelsius or QaaWS related. You can copy to MS Office InfoPath with steps described below.

Web Service Connection on fresh SUM formula is zero

I am using Xcelsius SP1. I have a field in the spreadsheet that has the formula "=SUM(H12:H16)". I am using a Web Service Connection to refresh the data. Following a refresh from the web service connection the field with the SUM formula is 0. I have discovered that ff the values in SUM range (in my case H12:H16) are identical to the refrehsed data then the formulas results willl be 0. If one of the sum values is different from the original values then the sum formula works. Is this a bug? Is there a work around?

I had a problem with the data format after getting number-values from my web-service, because every number-value I got was not a number - it was a string.
so I had to convert all the data in Excel from string to number values. after that everything works fine for me.
you could try that out....

Web Service Connection Date Input Values Converted to Number

I am using a Web Service Connection that has an input value called 'ModifiedOn' that is a date type. The problem that I have is that instead of sending a date string like '2008-08-04' it sends a number '39665' as the input to the web service method instead. Is there a way to force a date string to be returned instead of the number?
Here is the XML that is being sent to the web service method from Xcelsius:

Hi Aaron,
You may want to try formatting the cell of "ModifiedOn" to a TEXT format instead of date to get yyyy/mm/dd formatting to appear.
It seems that Xcelsius automatically converts any type of date-specific formatting (as specified from Excel) to a date serial, which is what you are seeing here.
Hope that works.

The code I use to get the connection is:
private DatosBlogsBndQSService getDatosBlogsBndQSService () {
Context ctx;
try {
ctx = ADFContext.getCurrent().getConnectionsContext();
WebServiceConnection wsc = (WebServiceConnection) ctx.lookup("DatosBlogsBndQSService");
System.out.println("wsc:"+wsc.toString());
DatosBlogsBndQSService proxy = wsc.getJaxWSPort(DatosBlogsBndQSService.class); // line 62
return proxy;
} catch (NamingException e) {
e.printStackTrace();
return null;
Finalmente la configuración del recurso es:
<Reference name="DatosBlogsBndQSService" className="oracle.adf.model.connection.webservice.impl.WebServiceConnectionImpl" credentialStoreKey="DatosBlogsBndQSService" xmlns="">

When the Web Service did not require authentication to work without problem, the error arises when you need to login and use the "ADF Web Services Connection", is there some other way to log in using the Web Service proxy client directly?
Any help is welcome.

Hi Shay.
I not use Web service data control, I use only Web Service proxy and the client class for populate data to view object programmatically.
However, in a test class do I have this:
public class WordPressCliente {
private final static Logger logger = Logger.getLogger(WordPressCliente.class);
public WordPressCliente() {
super();
private DatosBlogsBndQSService getDatosBlogsBndQSService () {
Context ctx;
try {
ctx = ADFContext.getCurrent().getConnectionsContext();
WebServiceConnection wsc = (WebServiceConnection) ctx.lookup("DatosBlogsBndQSService");
System.out.println("wsc:"+wsc.toString());
DatosBlogsBndQSService proxy = wsc.getJaxWSPort(DatosBlogsBndQSService.class);
return proxy;
} catch (NamingException e) {
e.printStackTrace();
return null;
private DatosBlogsPT getDatosBlogsPortClient() throws Exception {

System.setProperty("http.username", "atsistemas");
System.setProperty("http.password", "atsistemas2011");
DatosBlogsBndQSService integracionWordpress = new DatosBlogsBndQSService(url,qName);
DatosBlogsPT wordpressPT = integracionWordpress.getDatosBlogsBndQSPort();
if (ArchivoUtil.getInstance().getPropiedad("ws.integracion.wordpress.autenticacion").equals("true")) {
System.out.println("hay que validar el WS");

bp.getRequestContext().put(BindingProvider.USERNAME_PROPERTY, ArchivoUtil.getInstance().getPropiedad("ws.integracion.wordpress.usuario"));
