SAP XI versus Sonic's Enterprise Service Bus

Hi,
Question 1:
In David Chappell's book 'Enterprise Service Bus', the Sonic ESB is described. He says that the ESB is more than a hub-and-spoke integration broker: ESB is a MOM and above that several 'generic' services, which handle the traffic and routing on the bus, for instance:
- Transformation service
- Content based routing service
- Orchestration service
- Splitter service
- Etc.
Is this concept adopted in ESA? If so how is this functionality implemented?
Question 2a: does XI uses xCBL as a XML-dialect?
Question 2b: does XI make use of the canonical-XML concept (by using xCBL) ?
Thanks in advance!
Greetings Theo

As answer on question 1:
No I never found any documentation from SAP that described a ESB solution. So al the knowledge must come from other vendors in your case from Sonic.
But there is hope you can use XI in a ESB way. You must only (add) configure the ESB parts. This is done by adding a service repository for example the UDDI server in combination with some BPML engine.
By adding it al together you can execute your business processes over multiple system platforms using SOAP in a synchronic way.
This is the basic concept of a ESB.
The answer to question 2.
I dont know if XI has build in support, but a know that there are free tools that can handle Canonical XML. So you can make a service your self to handle the Canonical XML documents.

How to call proxy service at enterprise service bus using flex

Hi
I have a proxy service located at wso2 enterprise service bus. How can i call that proxy service using flex?
Regards
Minal

Hi Minal, I think you can communicate with wso2 using mx:HTTPService or mx:WebService, you just need to find out which services you'll be consuming and then create the flex app to present and interact with those services.

I also think that same way. I do not know what is so apecial about BEA Aqualogic ESB and other market matured ESB products such as TIBCO & SONIC. The samples which BEA has given in their evaluation guide are very simplistic. BEA should do more to provide extensive knowledge/features about their Aqualogic line of products.

What is SAP ESB (Enterprise Service Bus)?

Hi fellow sdners gurus I have been reading threads about SAP SOA and ESB.
I do not want to start a debate on wether XI is an ESB, but more of a statement to what is SAP ESB (if XI it is, then be it).
1) What is SAP ESB (Enterprise Service Bus) today (I could not find a clear answer to is)?
2) Who uses this SAP ESB in production currently and what kind of environment (i.e. strictly SAP backend systems, or combination of various vendors backend systems)?
Can someone share some light on this topic?
As a reminder, an ESB is expected to exhibit the following characteristics (source Wikipedia):
     It is usually operating-system and programming-language agnostic; for example, it should enable interoperability between Java and .NET applications.
     It uses XML (eXtensible Markup Language) as the standard communication language.
     It supports web-services standards.
     It supports various MEPs (Message Exchange Patterns) (e.g., synchronous request/response, asynchronous request/response, send-and-forget, publish/subscribe).
     It includes adapters for supporting integration with legacy systems, possibly based on standards such as JCA
     It includes a standardized security model to authorize, authenticate and audit use of the ESB.
     To facilitate the transformation of data formats and values, it includes transformation services (often via XSLT or XQuery) between the format of the sending application and the receiving application.
     It includes validation against schemas for sending and receiving messages.
     It can uniformly apply business rules, enriching messages from other sources, the splitting and combining of multiple messages and the handling of exceptions.
     It can provide a unified abstraction across multiple layers
     It can route or transform messages conditionally, based on a non-centralized policy (i.e. no central rules-engine needs to be present).
     It is monitored for various SLA (Service Level Agreement) threshold message latencies and other SLA characteristics.
     It (often) facilitates "service classes," responding appropriately to higher and lower priority users.
     It supports queuing, holding messages if applications are temporarily unavailable.
Your help is greatly appreciated.
Kind Regards,
Jean-Michel

AquaLogic Service Bus and XQuery Mapper

Hi all,
I'm new about using AquaLogic Service Bus and XQuery Mapper. I'm using alsb250_wls920.
To understand better the details I've developed two very simple EJBs stateless related to a generic CarRental scenario.
The idea is the following:
- EJB1 exposes a method for retrieving available cars from company A
- EJB2 exposes a method for retrieving available cars from company B
The method signature is the same:
public CarVO[] getAvailableCars(Category category, Double price)
the only difference is about the CarVO definition where one exposes more attributes than the second one (and also the package is different).
The goal is designing a new proxy service called getAvailableCars that calls the two above services and returns a set including all available cars from both companies.
The returned CarVO is the sum of all attributes from two above CarVOs plus a string company attribute.
So in AquaLogic I've defined:
- a JAR resource for importing my CarRental.jar
- two BusinessService resources related to the two above getAvailableCars services (from company A & B), called getAVISAvailableCars & getHertzAvailableCars;
- I've exported the two WSDLs from the two above BusinessService resources directly from AquaLogic console;
- I've written manually the WSDL 'getAvailableCars' that I use in the next proxy service definition
- a getAvailableCars_1 proxy service resource
Before completing the proxy service definition, I've decided to use XQuery Mapper for defining my trasformations.
But I got some errors when I try to import the WSDLs.
For importing simply I've created a wsdl folder inside my project and copied into it the 3 WSDLs definitions.
Because there are errors in 2 of these WSDLs (getHertzAvailableCars.wsdl, getAvisAvailableCars.wsdl) when I create a XQuery Transformation, I'm not able to select any source schema.
But getHertzAvailableCars.wsdl, getAvisAvailableCars.wsdl have been generated directly from AquaLogic console and I don't understand why XQuery Mapper complains about them.
If needed I can post also the CarRental.zip eclipse prj (that contains the above two EJBs) and CarRentalAqualogicPrj.jar AquaLogic prj (passphrase is aqualogic).
I thank you in advance for any suggestion.
Regards
Patrizio

Publish BUS1065 object to Enterprise Service Bus (Tibco)

Dear forum members,
We are trying to find out if a concept we designed will work. Our goal is to publish a full business object e.g. BUS 1065 (Employee) to the Enterprise Service Bus (Tibco JMS technology).
We plan to customize change pointers to the BUS object, which will trigger a replicate of the BUS object. We hope to create an outbound iDoc which will contain the full BUS object. The ESB solution will trigger a JMS publish on receiving the iDoc.
Does anybody has experience with replicating a business object for a non SAP receiver? Will our concept work?
kind regards,
Richard

Oracle Service Bus and Financila Message Designer

Hi,
I am new to OSB and FMD so want some good working examples/samples which can explain how to call the FMD cartridge from OSB.

Oracle Service Bus 10gR3 contains the JCA framework which will eventually allow us to exploit the whole set of JCA adapters currently in use in BPEL Process Manager. Over the next few months several JCA adapters will be certified to be used with Oracle Service Bus - the Database adapter is one of the first of these.
As for SOA Suite and WebLogic bundling, let me explain. SOA Suite contains the following products:
BPEL Process Manager
Business Activity Monitoring
Business Rules
Web Services Manager
Complex Event Processing
B2B
ESB (the old Oracle ESB product)
Service Bus (formerly AquaLogic Service Bus from BEA)
This does not come with an application server as the suite is hot-pluggable (i.e. can be used with a number of application servers). However, the preferred (and cheaper) approach is to purchase SOA Suite and WebLogic Suite (which contains iAS, WebLogic Enterprise Edition, Coherence, JRockit with 100ms deterministic garbage collection and WebLogic Operations Control). This is because some of the elements of the SOA Suite only currently run on iAS (B2B) and some only run on WebLogic Server (Oracle Service Bus) although in the future these will also become hot pluggable.
To find out more, check out the SOA Suite and WebLogic Suite pages below:
[SOA Suite|http://www.oracle.com/technologies/soa/soa-suite.html]
[WebLogic Suite|http://www.oracle.com/appserver/weblogic/weblogic-suite.html]
You will find the DataSheets are particularly useful for giving you an overview of the suite.
Hope that helps.

Oracle service bus and database connectivity

Since currently OSB does not support Adapter Framework, what are currently options for using DB Adapter type functionality in Oracle Service Bus (ALSB).
It seems JMS and other transports are very well supported, but how do we use DB Services?
Please if someone can provide some insight into this.
thanks

Oracle service bus and composing two web services

All,
Do let me know your thoughts on this.
Currently we have two web services
Web Service 1 - Verify Eligibility
Web Service 2 - Approve Proposal
Web Service 1 has one operation and accepts a well defined set of input parameters similarly web service 2 also exposes a single operation and accepts a set of input parameters.
These are deployed and running in our environment.
Now we have a requirement to stitch together these two web services and expose them as one single composite web service on the Oracle Service Bus 11g.
I want to create a proxy service on the OSB as unified web service (having its own WSDL) by composing the operations and input plus output parameters of the aforementioned two web services.
This way we can publish the WSDL to the front-end apps and they will trigger it with the required parameters and the proxy service will orchestrate the call to WS1 and WS2 and send the final output back to the calling client.
I was able to create an outbound call from the Proxy service to the underlying business services but I am not able to expose the Proxy service as web service with a WSDL i.e. create the proxy service by choosing operations of Web service 1 and web service 2
Please let me know your thoughts on this.
Regards,
Sushant

Thanks Atheek
The proxy service I tried to create orchestrate 2 web services.
But where we are struggling is How can i make this proxy service (composite) as a web service along with the WSDL.
The proxy service should be able to accept calls from the client with set of inputs representing both the underlying web services and coordinate calls b/w these two services and return consolidated output back to the calling client.
I am not finding a way to create a proxy service (web service along with the wsdl) which is representative of the underlying web services in a consolidated manner that can accepts inputs on behalf of both the underlying web services, orchestrate calls b/w the 2 web services and return the final output back to the calling client.
example modified to keep it brief
web service1
operation name: Verify Eligibility
Input: Complex type (String name, int Id, String address)
Output: Complex type(String approval status, int Id, String reason)
web service2
operation name: Approve Proposal
input: Complex type(String approval status, int Id, String reason, int Amount, int EmployeeCount)
Output: Complex type (String final status, String recommendation)
Composite Proxy Web Service
name: Composite Eligibility and Approval
Input: Complex type ( String name, int Id, String address, int Amount, int EmployeeCount)
Output: Complex type(String approval status, int Id, String reason,String final status, String recommendation)
The composite proxy should be created in a manner to jam the inputs of both the underlying web services and expose a representative interface on behalf of both the web services. This composite web service interface creation (WSDL) is where we are struggling a bit.
Because the calling clients need a unified WSDL to able to communicate with the composite web service.
Do post your thoughts.
Thanks Again,
Sushant
