WebServices and JCO

Hi I'm a newbie in SAP area.
I'm a java developer, my task is to create a set of WebServices in NetWeaver which will connect to SAP backend. For communication with SAP I can use SSO.
I've created a stateless session EJB with parameters ssoCookie and username.
I've selected to use authorization using Ticket module.
I have a client which is able to connect to the WS (the client is written in JS - AJAX)
The problem is that the parameter ssoCookie seems to be useless, the session must be present in the request to the WS.
Can I retrieve it somehow? I haven't found any way in VI interface or in some SOAP Extension..
My question is, how can I retrive the ssoCookie in my Java code?

HI,
Please look at following weblog
/people/sap.user72/blog/2004/10/25/sap-logon-ticket-based-single-sign-on
it might help.
Thanks,
Tuhin

Consuming a webservice and attributes

I'm trying to noodle my way thru consuming a webservice and
it is not making sense when I'm trying to get attributes from a
webservice. Can someone point me in the right direction. I've
included what the xml output looks like and my cfinvoke and a
cfdump of the invoke return variable. I just don't know how to
bring back that array of course ids??
The service returns course ids

I found a way to get the soap request into an xml document.
It was not intuitive to me but works.
Basically rereading this post:
http://www.houseoffusion.com/cf_lists/messages.cfm/forumid:4/threadid:44797#233359
gave me more insight. The tostring function appears to allow me to
get the raw xml that CF is struggling to noodle out.

Webservice and BPM; connection AFW failed

I have created the following integration process:
1. Asynchronous receive step of a xml file;
2. Synchronous send step to invoke webservice;
3. Asynchronous send step of the response file.
In this process XI will read a xml file from a directory on the server, convert this file to a SOAP request, call the webservice and convert the SOAP response to a xml file. This file is then sent to the same server directory.
When I look in SXMB_MONI the whole process is set to ok. The response of the webservice is in the payload of the XI response message. (This is the message from my integration process to the inbound message interface.).
But the response file never reached its destination.
When I look at the file adapter monitor it reports: "Up and running - no message processing until now".
And when I look at the message monitoring, there are the following messages:
2005-07-29 11:30:55 Success The message was successfully received by the messaging system.

IDoc to webservice and get the response back into another IDoc.

Hi guys
We have a scenario where we need to send an IDoc to webservice and get the response back into another IDoc.
Questions:
1. Is this scenario possible without a BPM? or do we need to use BPM (Sync-Async bridge).
2. Is there a Async to Sync bridge in BPM?
3. How do I use this bridge in my scenario and customize it?
4. If not possible, provide me the related docs using BPM for the same scenario.
Appreciate your quick response

Webservice and UI codes in one application

Hi,
We have two applications, one for the UI and one for web services. Both of them have Model project. Hence, we are thinking of merging then into one application which contains three projects: UI, Web services and Model so that both UI and Web services share the same Model project, no redundant codes. Just wondering is that a good design, will there be any issues? So can it be generated two deployment EARs files within one application?
Please advise.
Thanks
-Mina

you can have your approach itself.. but.. both webservice and the UI project will be have a dependency on the model project.. but you cannot reuse the model project any where else..
the suggestion given by shay, helps you to use the model library in both UI and webservice.. and can also extend to any other project which needs to access the model project..
in this case you are refering only the libraries of model project.. so no direct depenedency..

Differences between webservice and proxy

Hi guys.
Which are the differences between webservices and proxys?
If I have a XI adapter (proxy) or Soap Adapter in Pi in both a Proxy Abap is created in SEECC to consume the service so I cant see the differences...
Regards

If I wanted to consume a webservice exposed in Pi by a Sender SOAP Sender, what would I have to do?
Nothing exceptional.....just define a message structure in PI....create a message interface....generate a WSDL for this Message Interface.....use the URL from this WSDL to send message.....it is a normal SOAP --> XI scenario.....many references are readily available on How to do this.

Abhishek.

Query SAP BW via XMLA Webservice and save response to HD

Hi,
I´m currently working for an QM Project to create an Overview-page with figures from various BW-Querys. Unfortunatly the the BW-Performance isn´t fast enough to execute a lot of Querys in realtime, so I can´t use the Web App Designer.
To improve performance I want to execute those querys once a day and save the result sets on hard disk. To get the data out of the BW I want to use the XMLA-Webservice which is already running.
Is there a simple way or application to send my XMLA to the webservice and save the response on hard disk?

You can use XMLA web service or the queryview web service to get the data in XML format. The queryview XML service is only available from BW 3.5, see attached documentation.
http://help.sap.com/saphelp_nw04/helpdata/en/d8/3bfc3f8fc2c542e10000000a1550b0/content.htm
Ther is also an How to document available for XMLA under the BW 3.0B section.
If you are looking at a report with no navigation you can use the pre-calculation of the web reports with reporting agent which will create a pre-calculated HTML output on the BW server. Everytime you access the web report the pre-calculated HTML output will be displayed and the performance is great as the data is not accessed at runtime.

Can we wrap a RFC as webservice and use from external java application ?

Hi Friends ,
 Our scenario is call a webservice ( wrapped form of RFC) from a external java application which will pass the input to that webservice and get back the result .
 How XI will play a role here ?
 Can we wrap a rfc as web service ?
 Any blogs for that ?
 Can you please give a brief details about this ?
 Expecting yoour asap
Best Regards .,
V.Rangarajan

Hi
Can we wrap a rfc as web service ?
Yes.
To use the SAP Web AS 6.40 you need to build a wrapper in the 6.40 system. This is a remote function call (RFC) enabled function module with the same interface or a similar interface that internally calls the required RFC-enabled function module in the old 4.6x system via RFC. The wrapper then can be exposed to the outside world as a Web service. Another option is to use the Integration Broker capabilities for calling Web services in an older system.
How XI will play a role here ?
XI will pass the input to the external java application and get back the result to the webservice

How to use Adaptive WebService Model with CAF WebService and Complex Type

Hi All,
I am trying to use the Adaptive Web Service Model and call a WebService generated by the CAF. The return type of the WebService is a Complex Type.. I receive an exception when trying to instantiate the Model Node.
Does anybody know how to use the Adpative Web Service Model with CAF WebServices and Complex Types as return type?
Help is appreciated..
Thanks, Johannes

Thanks Mukesh.
It is not possible to apply the Service Controller Template on Enterprise Java Bean Models as described in the Document. When I try to aply the template on the EJB Model, NWDS says: Only Webservice Models and RFC Models are supported...???
I did not find any information about how to return complex types in AWS.. in this document???
Is there such information available? Has anybody ever done that? There must be a way to do that.. Is is the standard approach, isn't it...? Please help me out there.. I need to get this running..
Thanks, Johannes

BAPI - XI - webservice and response back to BAPI

HI experts,
could anyone please explain the step by step procedure for the below scenario in XI.
1.Bapi ->2.XI -> 3.webservice -> 4.XI -> 5.Bapi
BAPI must invoke a service in XI which invokes a webservice and fetches the data from external system, the response received back in XI is mapped to the BAPI.
a) How to configure BAPI in SAP R/3 to invoke XI service
b) how to configure the communication channel for RFC and SOAP
please provide links for step by step procedure.
Thanks & Regards,

Weblogic webservices and JSP

Hi Folks,
I have been stuck with this issue for quite sometime now. I have developed a simple webservice using a java class. It looks something like this..
public class ReceiveMessageClass{
 public void receiveMessage(String msg){
 logIt(msg);
 //Store 'msg' in a memory variable so that the JSP can ping it every 10 sec and read it..
}Now, I need a webpage to look at all the messages I recieve at this webservice. Sounds pretty easy? I have done this with Axis. I can create a WAR and my webservice and my JSP can co-exist and share a variable in memory. But with weblogic, a EAR is created and I am not sure how to get my JSP into the EAR. I am not sure how I can store this 'msg' into memory(some static vbl) and then have my JSP read it and display it.
Any suggestions?

I do not see any weblogic classes in the stack trace. So could this
be something to do with tomcat?
If you are just using the client side of the web services stack, you
only need the Client.jar and webserviceclient.jar file in your war.

Call a webservice and get back a value within an ESB...

Hi!
I'd like to call a webservice and get back a value from it within an ESB. But I don't know how.
I think, I must create a routing service, then a SOAP service, but how can I get back the value from the webservice, which I called in the SOAP service?
Or it is not possible to realize this within an ESB?
Thank You very much!
Viktor

When you take a look at the Soa Orderbooking example you can see how it works. You create a webservice that accepts certain parameters and these are bundled into an object. This object, in case of the Soa Orderbooking example a 'PurchaseOrder', is described using an Xml Schema. The XML Schema is used to create the ESB with. Using this xsd the ESB knows which object it can expect and this object can be used inside your ESB or inside a bpel process.

JAX-WS Webservices and WSServlet

Hi,
I am new to Webservices and started using JAX-WS services in Netbeans 6.8. In some tutorials I have seen that we need to configure the com.sun.xml.ws.transport.http.servlet.WSServlet class in web.xml for the webservice to respond the the particular URL. But in Netbeans6.8 I checked the web.xml but donot find any such thing but still the webservice is running perfectly.
Can anyone please explain if anything of the sort is required and if not,why is such thing mentioned in some of the tutorials? Also is services.xml or webservices.xml is required if we develop webservices in JAX-WS?
Thanks

Another question Kalyan,
We also have experienced problems providing a mechanism for API for Web Service clients to set keystore per service for two-way SSL implementation, implementing SSL with certificate for each connection.
We want to create a SSL conection with different keystore in each SSL connection.
Do you know how can do this task?
I've seen in http://docs.oracle.com/cd/E13222_01/wls/docs92/issues/known_resolved.html#wp1180999 Oracle WebLogic can do the following to solve it:
WlsSSLAdapter adapter = new WlsSSLAdapter();
adapter.setKeystore("./DemoIdentity.jks",
*"DemoIdentityKeyStorePassPhrase".toCharArray(), "JKS" );*
adapter.setClientCert("DemoIdentity","DemoIdentityPassPhrase".toCharArray());
*adapter.setTrustManager( new TrustManager(){*
public boolean certificateCallback(X509Certificate[] chain, int
*validateErr){*
return true;
*}); weblogic.wsee.connection.transport.https.HttpsTransportInfo info = new*
weblogic.wsee.connection.transport.https.HttpsTransportInfo(adapter);
*SimpleImplService service = new SimpleImplService_Impl(args[0] +*
*"?WSDL",info);*
Simple port = service.getSimpleSoapPort();
Stub stub = (Stub)port;
stub._setProperty('weblogic.wsee.client.ssladapter', adapter);
Are you agree with that lines?

Parameter JCO.Request and JCO.Response where null

Hi ;
I try to execute RFCtoRFC scenario. I have done all settings including receiver,sender agreement too.
But when i call rfc , i get following error
parameter JCO.Request and JCO.Response where <null>
My code that the calls a remote function is like;
CALL FUNCTION 'ZBAPI_EH_GET_DATA_GEN'
DESTINATION 'OLT200'
What would be the reason ?
Thanks

Hi,
in your RFC call, specify the data which is sent as RFC req msg from R/3 system in EXPORTING parameter if your RFC call is asycnh or both EXPORTING and RFC response msg structure in IMPORTING if your RFC call is synch.........in your report, use pretty printer and specify your RFC in CALL FUNCTION and then you will see the default calling procedure of your RFC.......then create a structue for your RFC req msg structure and response msg struc and fill it with data and then execute your RFC by using this CALL FUNCTION method.........

Trouble with WebServices and LiveCycle Designer ES 8.2.1.3

Hi,
Eventually I want to create a rather complex form that users will use to create a Change Request in our ticketing system through a webservice exposed by the same ticketing solution. However, right now I'm just attempting to create a very simple form as proof of concept. It's connected to a webservice that accepts two inputs a string and a datetime and returns 4 or 5 values that aren't necessary to display on the form but would be nice.
I've made the Data connection using the wizard and input the correct WSDL location and ES2 does see the webservice and pulls in the fields, including the execute button, that corresponds to the webservice. However, once I populate the fields and attempt to execute the call with the pre-packaged button, nothing happens. No errors and the call is never sent to the server. I've independantly verified that the webservice is reachable via the computer that I'm testing with and also that's it's accessible via others on the network. What appears to happen is that the call to the webservice is never sent from the PDF. If I change the execution option from Client to Server then I get an error message as such "Couldn't post data to''. Which makes sense, I think, since I don't have a LiveCycle Server.
Can anyone help? What am I doing wrong? I'd attach the file, but I don't seem to have the option.
Thanks,
CJ

Are you testing in Acrobat or Reader. My guess is Reader.....Reader does not support Web Service calls on its own. You can Reader Extend the form to allow Reader to do the Web Service call. To be able to do that you will need LiveCycle Reader Extensions server to do the extending for you.
For testing I suggest that you download the trial version of Acrobat (it does not have this restriction) and see if it satisfies your needs. Then you can decide if it is more economical to buy Reader Extensions server or buy copies of Acrobat for your users.
Hope that helps
Paul
