External Business Component vs Web Service

Hello,
We are using Siebel 8.1 and we are in need of referencing data in a external data source (DB2) that needs to present in a read only format this information within Siebel. We are trying to find the best path based on using
1. External Business Component
2. Obtain the data when needed via a web service
Option 1 is described in the training materials we have from the training courses we've taken, but web services are the corporate standard, since using a web service would insulate the Siebel application from changes that happen to the external database and would be reusable.
So far, we have been unable to determine how to call a web service from an applet that displays the data. The closest we've been able to come is to create a task flow to run the web service, and then place the data into a transient business component.
Does anyone have any recommendations or past experiences related to this they can share for the best path?
Thanks,
Bob

Hi Bob,
As you said you would be using web service approach. I feel following would be good method to display web service data in Siebel Applets
1.     Create Virtual Business Component (VBC)
2.     Create Applet Based on VBC
3.     Create Customer Business Service which will call web service and display data in applet
You can use “SIA Billing Extern Service” to minimize script. This Service uses input output in the form of integration object structure. So using it you can directly map web service output to VBC fields.
Thank you,
Sharad

Problem with query an External Business Component!

Hi guys,
I have created a Business Object based on an External Business Component.
In a WorkFlow in a step of type 'Siebel Operation' for operation I chose 'Query'.
In the section 'Search Spec Input Argument'
For 'Search Specification' I tiped " [Flag] <> 'N' " and no rows are selected :( (for sure there are rows in the table that are true for this condition)
For 'Expression Business Component' and 'Filter Business Component' I tiped my BC
I also would like to mentioned my BC has a field with 'Name' = 'Flag'
I am not sure that my description is quite clear, if you have any questions please ask.
Edited by: slyy on Jun 10, 2010 11:41 PM

Is the WF based on a Business Object i.e. does the WF record (where you specify Workflow Mode, and give it a name) have an entry in the Business Object field?
If it does, is the Business Component that you try to query on the driving business component of that business object?
If not, then that is the problem.

Exposing business rules as web services in 11g

Hi all,
I have deployed my business rules in Enterprise Manager, but the test button is disabled and I'm getting the next message: "In Enterprise Manager only can be tested composites that are exposed as web services". Does anybody knows how can I do that?

There are a couple of ways you can do it.
1. Drag a Web Service Adapter in the 'Exposed Services' panel in your composite and during configuration choose the WSDL of the Decision service i.e Rules. This will expose the rules as a web service if not already.
2. Double Click on the Reference icon on the Decision Service component (small rounded blue arrow). An Update Interface window will pop up. Check box 'Create Composite Service with soap binding' and select the appropriate port type from the available list.
You can now invoke your rule as web services and even test them from the EM console

Expose Business rules as Web Service

Hi,
I'm quite new to business rules, and I haven't found any definite information about can I and how expose business rules application as Web Service? In Decision Functions I can check "Will be invoked as webservice", but how can I deploy it on server and so on?
Thanks in advance.

Hi PK,
Sorry What i meant was composite service, not web service
Used wrong wording
In your composite if you have only businessrules as a component and if you are exposing your BR as service, and if u deploy that process it will give you a wsdl for that composite, which means for BR. Because the client is calling BR it self.

InstantiationException when trying to reference an external jar in my web service sample

Dear all,
I'm working with Weblogic 6.1 SP3 (on NT platform) and, starting from weather
weblogic web service sample, I'm trying to build my first web service sample.
I developed a simple EJB (called OrderManager) that exposes the following functionalities
in its remote:
import com.bosslab.abs.beb.sci.ServiceHeaderVO;
public interface OrderManager extends EJBObject {
public OrderManagerServiceResponseVO
submitOrder(
ServiceHeaderVO header,
OrderManagerServiceVO data) throws Throwable;
the ServiceHeaderVO interface is in another package and it is included in an external
Beb.jar.
This Beb.jar is located under serverclasses in mydomain directory and it is included
in the classpath set in startWeblogic.cmd.
Using wsgen weblogic task & ant I created my WSOrderManager.ear and I deployed
it.
Now no problem testing the EJB (OrderManager) with a simple client (in order to
verify that classpath is correct and also the EJB is running properly).
Also no problem pointing out to this URL "http://localhost:7011/ordermanager/com.bosslab.abs.mediator.OrderManager/com.bosslab.abs.mediator.OrderManager.wsdl"
to see the WSDL of my web service.
But when I run the web service client I got the following error:
Exception in thread "main" ------------- Remote Stack Trace ------------

It seems that there is a problem to instantiate the com.bosslab.abs.beb.sci.ServiceHeaderVO
class included in the Beb.jar, so I thought the problem was related to the classpath
setting, maybe Beb.jar is not set properly in some place ...
To try solving this problem I did these steps:
-> exploded my WSOrderManager.ear
-> created a lib directory and put into it the Beb.jar
so now the ear structure is:
lib/Beb.jar
MediatorOrderManager.jar
META-INF
web-services.war
-> modified the application.xml, adding:
<module>
<java>lib/Beb.jar</java>
</module>
-> modified the Manifest.mf, adding:
Manifest-Version: 1.0
Created-By: 1.3.1_03 (Sun Microsystems Inc.)
Class-Path: lib/Beb.jar
-> regenerate the WSOrderManager.ear
jar cvf WSOrderManager.ear lib MediatorOrderManager.jar ...
-> and redeployed the ear
But after stopping/starting my instance, I got yet the same error when I run my
client.
Could you please help me to understand how solving this problem ?
I thank you in advance
Kind regards

The WSDL is generated from my web service. I made heavy revisions to my web service which, in turn, affected the resultant WSDL. The changes I made to my web service were almost exclusively related to object substitution. For example, prior to the change I was referencing object A from my web service; after the change, I was referencing object B. The objects that I'm referring to are XMLBeans, if that matters. I can't really describe it more than that without actually showing you the WSDL.
I would post the WSDL file here to allow you to try to create a types jar out of it, but the WSDL exceeds the 30000 character limit for this field. There is no way for me to attach the WSDL to this post.

Books of business - supported via web services

Are books of business supported in R15 via web services interface? If we create a new Contact, Account or Opportunity, can we associate it to a specific book? I can't find any documentation on this subject.
If not, what's the point of using this functionality? We have over 13,000 different zip code ranges in our territory structure in Oracle 11i CRM, and would like to be able to maintain some sort of parallel structure in OnDemand via web services integration.
Are we stuck with creating Sales Team records for all object types? Seems very cumbersome to have to add a specific user to 100,000 different records, when we could simply assign them to a single book of business and accomplish the same thing.
Thanks,
Scott

Scott, web services will not be supported for book of business in R15. However, I passing this information to our On Demand product marketing. Thanks for the feedback.

Exposing Business Object as Web Service

Hi,
I've designed a Business Object and would like to expose its findAll Operation as a web service. The wizard tells that the operation has Improper operation message cardinality". While browsing through saphelp I found this: http://help.sap.com/saphelp_nwce10/helpdata/en/44/24128b347c1c9fe10000000a11466f/content.htm
Thats nice to know but doesn't solve my problem. How do I create a web service that returns ALL objects?
Thanks in advance for your help.

CE/CAF: Expose service as Webservice

Hi,
you need to create wrapper method of findAll,
The reason you are not able to expose it as service because findAll resturning array of values instead of one response (or candinality of return is 0..n). So create one wrapper complex type add your BO as datatype of that complex type with multiple cardinality,
In new method add this complex type as response (with cardinality 0..1) and within code call standard findAll and mapp return value to complext type.
It will work.

Expose ADF Business Components as Web Service

Hi,
In order to expose ADF BC as Web Services, and return a set a rows from a table, I have followed the tutorial on this page :
http://www.oracle.com/technology/tech/webservices/htdocs/series/pattern/
However, the set of rows returned are un-typed XML elements, because the method is :
public Element getEmp(int empNo)
getEmpView1().setWhereClause("empno = ?");
getEmpView1().setWhereClauseParam(0, new Number(empNo));
return (Element)getEmpView1().writeXML(1,Row.XML_OPT_ALL_ROWS);
As a consequence, in the WSDL the response port is returning a complex type with an "<any />" element. Instead, I would like the response complex type to be an Employee type.
How can I get the AppModule method to be something like :
public Employee getEmp(int empNo)
< what is here ? >
Can I generate the Employee class automatically with ADF BC and serialize it to expose the method as a Web Service ?
Thanks.

When the codes runs to the line IRetCode = oCompany.Connect(), it will return an error code -8006. Those session got the correct information from the web.config. Then exception is throw in.
I try restarting my com and restarting my suite manager. Usually this will solve the problem. However, it won't for this time. I hope will receive some solutions for my problem. Thanks for your time.

Hi,
Try To Set the db server type to MS SQL 2005 (value 4)
oCompany.DbServerType = BoDataServerTypes.dst_MSSQL2005
or
oCompany.DbServerType = 4
and
oCompany.UseTrusted = False

Problem in External Debugging for the Web service if SAML is Configured

Hi All,
I am facing a problem . I will tell you the exact process :
1. I have provided a external breakpoint in the ERP system.
2 . SAML is configured on both Consumer as well as Provider side.
3. try to execute the process Remotely, I am not getting breakpoint in the ERP system
If I remove the SAML and Provide basic Authentication, i am able to get. it seems there is some configuration parameter which are missing in the SAML Configuration.
Please advice how to check for the same.
Regards,
Kapil.

Hi Kapil,
I think the request is falling over with SAML authentication issues between the consumer & provider & that's why it's not triggering the breakpoint. I would first try tracing the request when it reaches the SOAP runtime of the provider using SAP Note 1254821. See the section towards the bottom under 'Error Analysis'.

Adding Invoices into SAP Business One via web service.

Hello!
I am partially done with my project. However, I am down to a couple of problems which hinders the progress of my project.
When I create an invoice with 2 items it will be inserted perfectly into the SAP Business One. However, when a second invoice with another 2 items is created the newly inserted invoice will reflect 4 items. 2 from the first invoice and the remaining 2 from the current invoice.
May I know what is the problem? I have been debugging for the past 2 nights and i couldn't find any headways.
Your help will be greatly appreciated.
Thank you!

SBL-DBC-00104 error using External Business Component

Hi all,
I'm trying to use a EBC for querying datas in the Export View. It works fine the most of the times but in some querys, it shows the error
SBL-DBC-00104: Error retrieving next record from the database.
ORA-24345: A Truncation or null fetch error ocurred
Looking for the cause of these errors, I have discovered it ocurrs in a calculated field. This field has this calculated value
[Accion Cargo Modificado por] + ' - ' + [Updated By]
The problem of this is in [Accion Cargo Modificado por] value. In database, this field has the value "RED_DESARROLLORED_SUP" and, after looking for SBL-DBC-00104 in google, I thought that the reason could be the length of this value, too long, but the fields [Accion Cargo Modificado por] and [Updated By] have the same length that the fields in database. Any idea about how put a length limit in a calculated value? can it be wrong because is a EBC? (I haven't this error in a similar BC with the same fields)
thanks in advance

I have discovered the error. The text length in EBC had the same length that the fields in my table in database BUT the columns of that table in Siebel Tools hadn't the same length. That was why my EBC didn't work.

How to deploy business objects web services on tomcat

com.sap.portal.ivs.global.ume.UMECLient.
Exception id: 11:17_03/07/08_0028_2739150
See the details for the exception ID in the log file
I did not use any ume attributes or ume api methods in the portal component .
I have also added sharingreference= portalserviceapplication name in deploymentdescriptor of the portal application which has the portal component.
Please provide any suggestion for the possible cause of error .

Hi all,
Please throw some light into this issue i am getting the following exception.
com.sap.engine.services.webservices.jaxm.soap.accessor.NestedSOAPException: Problem in server response: Proxy Authentication Required.
I have given the proxy settings in the com.sap.portal.ivs.httpservice in the portal and also
defined a proxy server in the Visual Administrator under Services -> Webservice Container -> HTTP Proxy Server
I am calling service in the following manner.
IPortalRuntimeResources runtime = PortalRuntime.getRuntimeResources();
   IService service = runtime.getService(IWS_P_Service.KEY);
   IWS_P_Service ws_service = (IWS_P_Service)service;
    Volumes from = new Volumes(Volumes.VOLUMES_KILOLITER_VALUE);
    Volumes to = new Volumes(Volumes.VOLUMES_LITER_VALUE);
    ChangeVolumeUnit cvu = new ChangeVolumeUnit(1200,from,to);
    // working upto here
     response.write("working");
     ChangeVolumeUnitResponse cvu_res = ws_service.ChangeVolumeUnit(cvu);
     double result = cvu_res.getChangeVolumeUnitResult();
     response.write(result+"");
It is working upto "working".
If any body has any solutions please post.
Thanks
