Callable Object - Web Service: Initialization failure in GenericServiceFact
Hello,
I am just trying to do the NetWeaver 7.0 exercise
"Callable Objects: Web Service
...In this exercise you will create a callable object as an external web service. A prerequisite to the exercise is that ... the web services container settings in the J2EE Visual Administrator must be set to allow access to the internet.
Author: Composite Application Framework Product Management "
However, when setting up the Callable Object, after entering the WSDL-URL given in the pdf I get the error "<b>Initialization failure in GenericServiceFactory when trying to load http://www.webservicex.net/WeatherForecast.asmx?WSDL</b> ".
Is it the missing activation of internet-access in the J2EE Web container? I can't find any such parameter in the J2EE-config tool (and where has the Visual Admin gone?).
Regards,
Jens

What SAP Business Objects Web Services to use with XI3.0
I'm new to BO and is tasked to install it.
What I've installed already is the BOE XI3.0 version and now want to install Xcelsius 2008 Enterprise.
What I can not figure out from the Xcelsius manual or SDN or OSS is what the Business Objects Web Services are the manual instructs you to install with Xcelsius.
I did find something called
BusinessObjects Web Services XI for Windows and downloaded it but is not sure if this is what I need to install as the business Object Web Services on XI 3.0
Can someone please direct me in the correct direction
Thanks in advance
LiezelHi,
i am not sure if i understand your question. If you mean Query as a Webservice (QaaWS), this component should be part of your XI 3.0 Enterprise installation. You could also use the flynet (www.flynet.co.uk) which is part of Xcelsius Enterprise 2008 SP1.
Best Regards

GP, callable object Web Dynpro Application (bespoke) not appearing in list
Hey y'all
We're developing our first GP, and we would like to call an existing bespoke Web Dynpro. When creating the callable object, we're selecting type Web Dynpro Application, but our Web Dynpro screen is not appearing in the drop down list on the next page. We think that this is because the application has been deployed to a different server (i.e. it has not been deployed onto the portal server).
So the question is, has anyone faced this problem before, and is there a solution?
Kind regards
JonHi John,
Please have a look at this Exception on creating GP Action
This will solve your issue definitively. Do not take care of a given SDA, just redeploy everything and make sure that everything is overwritten by selecting the right option.
Best regards,

Objects, web services and netbeans
I am trying to make a web service that returns an array of objects (where each object is a small number of strings). I shall list what I have done, if you just want to read the problem skip to <PROBLEM>.
1) Wrote .wsdl file [1]
In netbeans:
2) Generated web service from WSDL:
A) New web application, using the sun application server
B) New Web Service From WSDL (this gives an error, Illegal character in path at index 18: file:/<path of wsdl file>)
C) Right click on web service, Refreash service. No error
D) Run project, test web service, seems to work, returns null.
3) Consumed service:
A) New general application,
B) In main method, right click / Web Service Client Resources / Call Web Service Operation
C) Select method (getparams(String))
D) Add import org.impress.PortType; as prompted
E) Run project, Result = null
Now I want to add some data to what I am passing. First I return a new namespace.webservice._new.Paramarrayel (what netbeans decided the method should return). The client now shows that something is returned (org.impress.Paramarrayel@1bb5c09).
<PROBLEM>
Now this is where I get stuck. I want to add the data, the client knows there should be a .getGetparamreturns() function in the returned org.impress.Paramarrayel object but I cannot figure out how to add it in the server. I have tryed extending the namespace.webservice._new.Paramarrayel and namespace.webservice._new.Paramreturns, and adding a Paramreturns as a member variable of Paramarrayel but .getGetparamreturns() returns null in the client.
Anyone able to help?

Errot at creation of callable object (Web Dynpro Component (GP Interface))
Hi,
I have made a Web Dynpro component and it has been built and deployed without problems.
However, when I go to the Design Time in the portal to create the callable object, it dumps with this message:
500 Internal server error
The initial exception that caused the request to fail was:
java.lang.UnsupportedClassVersionError: bad version number in .class file

How to configure business objects web services
Hi can anyone tell me were can i find these web services in cmc, and how i need to configure these webservices.in order to talk externally with the java program.
my scenerio is, java program will kick off to send the parameters to the web services in business objects. The web services need to take those parameters from java and create a file and drop it locally or anywhereHi
Which version you are on?
if it is XI 3.x then, dswsbobje is the web application which is deployed on default tomcat, You can get the details of of all available web services by :http://BOEHOSTNAME:PORT/dswsbobje/services/listServices

Business Objects Web Service Interface for Scheduling (without Java SDK)
Task:
> use BO web service interface to schedule report generation and fetch job with generated PDF object without having to use Java (Webservice) SDK
Detailed requirements:
> get session ID : ok, session WSDL, <BO server alias>/dswsbobje/services/Session , method "session"
> schedule a specific report : in general clear, via <BO server alias>/dswsbobje/services/BIPlatform, method "schedule"
> set report format to "PDF": is that possible ? With which WSDL and method ?
> schedule right now and only once: is that possible ? With which WSDL and method ?
> can I provide a parameter value for that report ?
> does schedule response contain jobID for later fetching of completed job ?
> how to fetch scheduled job for check of completion ?
> how to check status of job concerning completion ?
> how to fetch created PDF from completed job ?
With focus on my research (have checked and tested with soapUI), WSDL interface of BO seems not to be sufficient to fullfil the upper requirements, so I have to use BO Java SDK, which is powerful enough. Am I right ? Can you provide insights how to fullfil the requirements with the web service interface ? Would make whole implementation simpler (invocation from Tibco, ESB implementation).The error you're hitting is presumably JBO-25030.
Look to the "merge" command. In the parent you specify just the key of the preexisting parent record, and then in the child you specify your new child record.

Does anyone know a reason why you cannot select certain operations like "findall" when trying to expose a business object as a webservice?
Regards
DanHi,
There is a excerpt in the CE 7.1 Doc that says:
Some of the operations cannot be exposed as Web service. For example, the query operations of the business objects cannot be exposed as Web services because they have output with multiple cardinality. All changes of input or output parameters of the business object or application service operations you expose as Web services reflect to the generated WSDL.
The page is:
http://help.sap.com/saphelp_nwce10/helpdata/en/44/24128b347c1c9fe10000000a11466f/frameset.htm
I don´t understand the reason quite well.
Best regards,

I made six wsdl web services using "Query As Web Services" of BusinessObjects XI 3.1. Then i converted these into restful web services using Netbeans.
Out of these, two web services are made for user1 and rest web services are for user2. User1 shouldn't have access to user2's web services and vice versa. How can i achieve this using SAP BO?i waiting your help?
is the Question more difficult to answer it?? -
Hi Experts,
I have requirement to create custom business object and create Web Service for that and use in external system (SAP ECC / SAP CRM / Third Party).
1) Is it possible to create custom object web service and used in external system ?
2) When we create the Web service from custom business object what the necessary steps(action : Create , Read , Update) require?
3) Sample Scenario :
My Custom Business Object
businessobject Custom_Integration {
element EP_VAL1 : LANGUAGEINDEPENDENT_MEDIUM_Text;
element EP_VAL2 : LANGUAGEINDEPENDENT_MEDIUM_Text;
element IP_RES : LANGUAGEINDEPENDENT_MEDIUM_Text;
I have created the Web Service using this custom business object.
3) How i can use this web service in external system? what are the prerequisite steps in external system to consume this service in it?
Please anyone have idea about this how to do this and how to achieve this using SDK and custom business object.
Many Thanks
MithunHello Mithun,
Does this section in the documentation help you:
SAP Cloud Applications Studio Help -> Developers Desktop -> Web Services
The entry "Task -> Create a Web Service" describes how to create a Web Service on your own BO
The entry "Task -> Test a Web Service" helps you how you can use it in a foreign tool / application.

Hi folks,
I'm trying to set up a JMS web service on a WebLogic 7.0 server.
I want this web service to listen for messages on a queue on
another server running WebLogic 6.1 sp2. Here's what I've done:
Created web service using WebLogic Workshop modeled after the
workshop sample SimpleJMS.jws. A file Email.jws contains the
following code snippet:
package datatel.jms.email;
import weblogic.jws.control.JwsContext;
import EmailControl;
import javax.jms.Message;
public class Email
// Public variables...
public String m_Message = "default email response";
public EmailJMS emailJMS = null;
// Protected variables...
protected String jmsURL = "http://predict.datatel-info.com:7250";
// Private variables...
private String name;
* @jws:control
private EmailControl Email_Ctrl;
/** @jws:context */
JwsContext context;
* Initialize the JMS connection to the predict server...
public Email()
System.out.println("\nEntering Email.jws constructor...");
// Initialize JMS on the Predict server...
emailJMS = new EmailJMS(jmsURL);
System.out.println("Exiting Email.jws constructor...");
Notice that the Email() constructor code above references my object EmailJMS(jmsURL).
This object intializes the JMS connection to the other WebLogic 6.1 server. Here's
the JMS initialization code in my web service:
public EmailJMS(String jmsURL) {
System.out.println("\nEntering EmailJMS constructor with URL..."
+ jmsURL);
Environment environ = new Environment();
environ.setProviderUrl(jmsURL);
try {
ctx = environ.getInitialContext();
System.out.println("Got new InitialContext..." + ctx.PROVIDER_URL
+ "\nTime is: " + new Date().toString());
qconFactory = (QueueConnectionFactory) ctx.lookup(JMS_FACTORY);
qcon = qconFactory.createQueueConnection();
qsession = (WLQueueSession) qcon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
/** USER receive queue and listener
queue = (Queue) ctx.lookup("USER_TX_Q");
user_recvr = qsession.createReceiver(queue);
user_recvr.setMessageListener(this);
textMsg = qsession.createTextMessage();
objMsg = qsession.createObjectMessage();
isConnected = true;
qcon.start();
// --- more code follows ...
The JMS connection is successfully made. When another JMS program sends a message
to the USER_TX_Q, the web service receives the message via the onMessage handler
in the EmailJMS class.
The problem arises when I try to invoke my web service from the WebLogic Workshop
browser Test Form. On invocation on my web service, the following exception occurs:

Service Response
When I comment out the instantiation of my EmailJMS(jmsURL) object, the web service
initializes just fine. However, I don't have the JMS connection to my other server.
What is this stack trace telling me? How do I receive unsolicited JMS messages in
a web service?
Thanks,
Bob GontarzHi Bob,
I have tested the same functionality as mentioned by you, and could not see
any errors, while testing using the Test Form. The JMS queue where I was
sending messages is on a 6.1 sp2 server.
Please find attached the two JWS files, which I used to simulate the
condition, one used for dispatching the messages and the other for receiving
the messages.
Please do let me know if your case is any different from the one I have
tested.
I look forward to your response.

BI Application Callable Object
Hi,
I am new to Guided Procedures.
I tried to use BI Application Callable Object under Services Type and i created a BI System in Portal to use in the callable object.when i use it in the callable object it is showing error cannot connect to system .
Can you help me how to create a system in Portal and help me with a scenario how to use BI Application Callable Object.
Regards,
Bala Baskaran.SHi KC,
When you start your process from GP Runtime, does the actual action/callable object open in a new window?
Have a look at this SAP Note:
[Error when executing a GP task - Page builder|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_bc_gp/~form/handler%7b5f4150503d3030323030363832353030303030303031393732265f4556454e543d444953504c4159265f4e4e554d3d393831353137%7d]
Although the error message you are getting is different, but if your callable object opens in a new window, then the problem (in most probability) is the same as mentioned in the SAP Note.
Also, try testing the Web Dynpro callable object in standalone mode. For more information on this, see:
